Too Little, Too Late? NV Energy Renews Solar NEM Grandfathering Request
(It's a few days old)
http://solarindustrymag.com/too-little-too-late-nv-energy-renews-solar-nem-grandfathering-request
by Joseph Bebon on July 28, 2016
As the debate over infamous net energy metering (NEM) changes continues in Nevada, utility NV Energy is again asking state regulators to grandfather in rooftop solar customers under the previous NEM rules. However, some solar installers have deemed the utility’s renewed request “too little, too late.”
In December 2015, a Public Utilities Commission of Nevada (PUCN) decision slashed NEM rates and established new fees related to rooftop solar, and some solar companies closed up shop in Nevada as a result. In addition to calling for the PUCN to completely reverse its decision, both the local and national solar industries argued that existing solar customers should be able to receive the NEM rates they initially signed up for in Nevada. After facing immense pressure, NV Energy – which, like many other utilities around the U.S., claimed NEM is a subsidy that unfairly burdens non-solar customers – made a last-minute grandfathering proposal in February. At the time, solar stakeholders called the utility plan a “bait and switch.”
Ultimately, the PUCN denied a NEM grandfathering clause, meaning existing customers have also been subject to the newer NEM rules.
Now, NV Energy has filed a new proposal with the PUCN that rooftop solar customers who either added their installations or had active NEM applications before Dec. 31, 2015, be allowed to cash in on the previous NEM rates for 20 years. The proposal resembles a recent recommendation from Nevada’s New Energy Industry Task Force.
“After a number of recent failed attempts to negotiate a resolution of this grandfathering issue with out-of-state private solar suppliers, it became clear that NV Energy needed to step up and act alone,” comments Paul Caudill, president and CEO of NV Energy, in a press release. “I have spoken with many of these net-metering customers personally and understand and empathize with their concern. We simply did not want to wait any longer to offer a solution on their behalf and believe our filing today represents the most efficient and timely way to do that.”
The utility has asked the PUCN to take action on its proposal within the next three months. In its press release, NV Energy also seems to place some blame on solar companies, claiming nationwide installers might have misled Nevada customers.
“Unfortunately, it appears that these out-of-state solar suppliers are more concerned with increasing the subsidies needed to run their businesses than taking care of their approximately 32,000 contracted customers [in Nevada], who are our customers, too,” says Kevin Geraghty, NV Energy’s senior vice president of energy supply.
“It seems that they created uncertainty for customers who purchased or leased a rooftop system by not clearly communicating that their rates were subject to change in future regulatory proceedings,” continues Geraghty. “Many of these net-metering customers entered into 20-year leases believing that they would be locked into a rate and that they would save money because NV Energy rates would increase every year. Neither of these sales pitches are true.”
Solar, wind, storage and big data: Why energy may soon be free
By Giles Parkinson on 1 August 2016
http://reneweconomy.com.au/2016/solar-wind-storage-big-data-energy-may-soon-free-27165
Global investment bank Citi is predicting that the combination of near zero-variable cost energy sources such as solar and wind, along with smart analytics and “big data”, may deliver what the nuclear industry promised nearly half a century ago – free energy.
“The notion of free energy came to prominence in the 1960s, as nuclear fusion was touted as a way to provide free energy,” Citi writes in the latest of its “Disrutive Innovations” series in a section focusing on Big Data and the energy industry.
When those claims were made about nuclear fusion, the technology was in the embryonic stage, and it turned out nuclear energy wasn’t free at all, but incredibly expensive, and getting more so by the year.
But wind and solar, along with demand and storage optimisation, may finally deliver on that promise, Citi says.
“Big Data and advanced analytics are developing rapidly to improve forecasting, automation, customization, and the democratisation of energy,” it says in its reports.
“The end result is that we are producing more energy with fewer resources ….. the goal of dramatically lowering energy costs for all, with the possibility of free energy in some corners, may finally come to fruition.”
Citi is not the only research institution making such forecasts, but is is sharp contrast to the general public discussion in Australia, which is dominated by those who insist that the old centralised energy system – slow, inefficient and expensive – will not and cannot be replaced by new technologies.
South Australia is now the focus of that debate, and the push-back against wind and solar by conservatives and, of course, vested interests, seeking to protect their sunk assets is striking.
But Australia is already well done the path to this transformation given its high level of rooftop solar and the fact that it is considered to be the world-leading market for household battery storage, and smart software.
Already, it has more than 1.5 million households and businesses with rooftop solar, totalling more than 5GW, and many will soon add battery storage. Smart software will allow households and businesses to pool their resources, and trade with each other – if regulators allow.
Citi says this “democratisation” of energy could see renewables and distributed energy resources (DERs) proliferate at the local level, and that will mean fewer new power plants.
Consumers could eventually “trade” energy with others, in the form of “transactive energy” – a concept that is already being trialled by utilities and community energy groups in Australia.
This, of course, has profound implications for business models. Instead of investing in large fixed assets, as they have done for the best part of a century, Citi suggests the utilities of the future will become distribution service platform providers.
The state of New York is already going down this path through its remarkable REV (Reforming the Energy Vision) program, and some analysts want it adopted in Australia.
Citi says REV is one of the most ambitious regulations put forth by a regulatory agency in changing the business models of utilities. The focus is entirely on distribution energy, creating the right regulations and rules for the appropriate platform and operations, as well as system integration and operation.
In the distributed, decentralised world, particularly in the electricity space where the supply and demand of electricity has to match instantly, ensuring a smooth and optimal operation of the grid necessarily requires advanced analytics to process the vast amount of data generated.
“Technology companies could provide energy network optimizing software or even operate platforms and energy companies that transition to providing services could become asset-light, as they could control how energy is routed and optimised,” Citi suggests.
“Third-parties or homeowners would become energy providers through Distributed Energy Rs and auto companies would become service and energy providers (e.g. through their battery technology).”
Citi says the fundamental technologies of solar panels, wind turbines, converters, and energy storage have been around for years, but having nearly half or more of total electricity supplied by wind or solar was previously thought to be impossible due to grid integration issues.
But Big Data and advanced analytics are helping the electric grid to function more seamlessly, enabling wind and solar utilization and penetration rates to rise more sharply, and integrating more distributed generation.
A lot of this comes down to predictive software. “Having more precise estimates of renewable generation allows the grid to schedule in the appropriate amount of backup generation and deploy other measures, such as demand-side management.”
One example is the creation of “virtual power plants”, which pool the output and resources of numerous solar and storage arrays that could be located in households, businesses, or CBD buildings or factories.
The software can bring these devices together and operate them as if they were a single power plant. Citi says these are critical because they negate the traditional response to rising demand in an area by building a new centralised power plant or adding new infrastructure.
Recently, the New York regulator denied Con Edison’s request for a $US1 billion upgrade in resolving equipment overloading. Instead, ConEd created the BQDM (Brooklyn Queens Demand Management) program that relied on both traditional utility and non-traditional customer/utility improvements at a total estimated cost of only $US200 million.
Those sorts of cheaper alternatives are being considered in Australia, but the regulators have been slow to catch on, and when large spending cuts are recommended the regulator is taken to court by the utilities,
Citi says this requires a whole new way of thinking. It would require pricing energy and ancillary services at the neighborhood or an even more micro level
“What does the future of energy look like?” the Citi report asks.
“Producers could tap previously stranded assets and do it quickly; utilities could be winners but only if they transform with the times; renewables, despite intermittencies, could operate as smoothly as traditional fossil energy; emissions should be limited as energy demand is optimized and renewables proliferate. Trillions of dollars are at stake.
“This is a story of how software will transform a hardware-dominated sector; it is the kind of creative destruction that demands fundamental changes in an entire sector.”
Back to the discussion about what our fossil fuel competition can do to us.

When Solar & Wind Prices Are “Too Low” And Solar & Wind Power “Too Dominant”
July 27th, 2016 by Zachary Shahan
http://cleantechnica.com/2016/07/27/solar-wind-prices-low/
Update: I think I buried the takeaway points a bit too far down below the industry background and definitions, so I’m bumping this summary up to the top (so you can understand the problem before reading more details on what leads to the problem and potential solutions):
1. Wholesale electricity is sold to the grid on spot markets in many places. Under such a system, power plant operators have the option to sell electricity from their power plants to the grid on a day-ahead, hourly, or other short-term basis. As long as the power plant operators sell electricity for more than the marginal cost of producing electricity (which almost $0 for solar and wind without subsidies, and below $0 with some subsidies), they make some money.
2. In a system where all power plants are solar or wind, however, that means everyone is bidding each other down to almost $0 (without subsidies). But selling electricity for just barely more than $0 for years is going to result in never earning back the money invested into the power plants to set them up (or company overhead) — non-marginal costs.
3. So, if we project out to a 100% renewables future, or even a future in which renewables are dominating but not capable of providing 100% of electricity, we need to figure out a way to compensate power plant owners for non-marginal as well as marginal costs — something different from the simple spot markets that many grids run today. How best to compensate for non-marginal costs in a competitive way is what is quite unclear at the moment.
[This is quite an “inside baseball” topic for CleanTechnica, but I think it’s a fascinating one and one that is ripe for discussing in this community and more broadly.]
For several years now, there’s been a bit of concern about how the energy industry will proceed as solar and wind take more and more of the market — and I’m not talking about integration or flexibility, but about the insanely low marginal (operational and “fuel”) costs of solar and wind farms (close to nilch).
To understand the issue, you have to have somewhat of an industry insider’s view of how electricity markets work (but not too much, so don’t run away as I explain a few key industry terms and processes).
In certain electricity markets, to get your power plant’s electricity onto the grid, you have to outbid other electricity providers on the wholesale spot market (under what is referred to as a “merit order” system). Given that your power plant is already built, what you have to look at in order to determine how low of a bid you can offer is what it costs your power plant to actually produce the electricity at a certain point in time. If you can produce another kWh of electricity for 3 cents, and you can sell it for 5 cents, you’re good to go. However, if you can produce another kWh of electricity for no fewer than 4 cents, and you can’t sell it for more than 3 cents, you lose out and you can’t sell the kWh of electricity.
Since wind and solar power have nearly no marginal electricity production costs (sunshine and wind are free, and no one has to operate the power plants as the sun shines down or the wind blows), they can outbid practically everything else. Thus, the more that solar and wind electricity becomes available for bidding, the more higher-marginal-cost electricity options get pushed off the table. At some point, of course, if a coal, nuclear, or natural gas power plant can’t sell enough electricity to cover its overhead (and marginal) costs, it is not financially viable to keep the power plant open.
The Switch by Chris Goodall – solar power is finally taking over
The transition to solar is happening faster than predicted, and now power can be stored when the sun isn’t shining. This book is a guide to the latest exciting developments

A sense of drift and apathy has pervaded the global warming and renewable energy debate for too long. The fossil fuel companies continue to dig coal and pump oil and gas; herbivorous idealists, scientists and ecowarriors emit their ritual opposition. The carbon load forced into the atmosphere continues to rise, and the general public seems resigned.
But 2016 is the year this will really begin to change. Chris Goodall’s book is wonderfully up to date but, thanks to the pace of change, even he couldn’t keep up with the avalanche of news and initiatives conspiring to justify his subtitle. In May, Shell announced a major move into renewables; on 15 May Germany received almost all its electricity from renewables; for four days from 7 to 10 May Portugal did the same. Goodall, who is an economist rather than a technologist or ecowarrior, explains why the change is happening now: the cost of solar electricity is falling much faster than anyone predicted. Solar power is approaching parity with fossil fuels and can only become cheaper as time goes by.
Sunny Portugal might run fossil-free for four days but what happens when the sun doesn’t shine and the wind refuses to blow? The recent Ren21 global status report, while reporting that clean energy investment in 2015 ($286bn, or £217bn) was more than double that for fossil fuels ($130bn, or £99bn), added the rider: “But the fast-maturing renewables sector still has to overcome storage limitations and the world’s dependence on infrastructure systems geared towards fossil fuels.” In the latter part of the book Goodall addresses this, explaining the missing factor – the final piece of the puzzle.
Goodall writes that the sun supplies enough power in 90 minutes to meet the world’s total energy needs for a year. When solar and wind installations reach a certain critical level, there will be periods when they produce far more energy than can be used. Electricity cannot itself be stored but that surplus electricity and indeed sunlight itself can be used to create liquid hydrocarbons for fuel, plastics and other chemicals and methane to drive gas-fired power stations at times when renewable output dips. This is not a pipe dream. An exciting project, launched as the Global Apollo programme in 2015 and taken up, thanks to Bill Gates’ ministrations, by 20 major governments at the Paris climate conference in December 2015, is to produce liquid fuels and methane directly from carbon dioxide using sunlight – in effect, mimicking the photosynthesis that every plant accomplishes so easily.

David Attenborough, one of the founders of the Global Apollo programme, has said: “If we could put a man on the moon in 10 years you mean to say we can’t solve the problem of getting one 500th part of the energy from the sun? It’s really a tiny technological problem.” It isn’t quite such a tiny problem, but lab scientists such as Peidong Yang at Berkeley and commercial companies such as LanzaTech in the US and Carbon Recycling International in Iceland are already showing the way.
The surplus solar energy of summer will be squirrelled away into liquid fuel and gas for winter, rather as the sun’s past bounty produced the surplus we now consume as fossil fuels. And this project has the backing of scientists, technologists, economists, governments, great foundations, major investors and even giant energy companies from the fossil era (because the liquid fuels and gas will use the existing infrastructure: a huge economic boon).
The “switch” is coming. It will probably take 20 years to make a major impact, but we should see the first fruits very soon. This book is the essential guide to this great benign change, although I could have done with some sense of the grandeur of what we are on the verge of achieving. For 4.5bn years, light has been pouring down on the earth, creating and sustaining the cornucopia of life. For two and a half centuries we have been living off hundreds of millions of years of stored sunlight. And for over half a century, scientists have been working to unlock the secrets of plant photosynthesis. This is now known down to the last atom, and this achievement should rank with Watson and Crick’s elucidation of the DNA structure. It’s time to put that knowledge to work for us.
SO Many energy experts out there......

Billionaire T. Boone Pickens Predicts Oil Prices Will Hit $70 Before 2016
Despite the relentless pullback in energy prices, billionaire T. Boone Pickens is holding firm on his $70.00 price target for crude oil. Prices are currently hovering between $52.00 and $54.00, reflecting a 44% decrease over the last 12 months. (Source: CNBC, July 10, 2015.)
Pickens’ comments come in a week where U.S. oil production dropped by 50,000 barrels. The lower price has forced 1,012 oil rigs out of business in the last year. However, many analysts are estimating that a deal between Iran and the United States will draw one million barrels of Iranian oil into an already crowded market.

You’ll Never Believe How Cheap New Solar Power Is
by Joe Romm Jul 18, 2016 9:29 am
http://thinkprogress.org/climate/2016/07/18/3797907/solar-energy-miracle-charts/
Solar energy has grown 100-fold in this country in the past decade. Globally, solar has doubled seven times since 2000, and Dubai received a bid recently for 800 megawatts of solar at a stunning “US 2.99 cents per kilowatt hour” — unsubsidized! For context, the average residential price for electricity in the United States is 12 cents per kilowatt-hour.
Solar energy has been advancing considerably faster than anyone expected just a few years ago thanks to aggressive market-based deployment efforts around the globe. Since it’s hard to keep up with the speed-of-light changes, and this is the fuel that will power more and more of the global economy in the near future, here are all the latest charts and facts to understand it.
If you are looking for one chart to sum up the whole solar energy miracle, Bloomberg New Energy Finance (BNEF) Chairman Michael Liebreich has one from his keynote address at BNEF’s annual conference in April titled “In Search of the Miraculous”:
Solar’s exponentially declining costs and exponentially rising installations (the y-axis is a logarithmic scale)
Thanks to sustained long-term deployment programs, Liebreich explained, “We’ve seen the costs come down by a factor of 150 since 1975. We’ve seen volume up by 115,000.”
“How much more miracle-y do you need your miracles to be,” Liebreich added.
What that chart doesn’t reveal is that the price drop and the sales volume increase are directly linked. There is a learning curve: Over the past four decades, for every doubling in scale of the solar industry, the price of solar modules has dropped roughly 26 percent.
BNEF has the learning curve chart in its “annual long-term view of how the world’s power markets will evolve in the future,” their New Energy Outlook (NEO) from June. In a section headlined, “Solar and Wind Prices Plummet,” BNEF says “The chart below is arguably the most important chart in energy markets. It describes a pattern so consistent, and so powerful, that industries set their clocks by it”:
BNEF projects that by 2040, the world will invest an astonishing $3.4 trillion in solar. That’s more than the projected cumulative investment of $2.1 trillion for all fossil fuels — and $1.1 trillion in new nuclear — combined.
The result of these investments and the continued learning by solar (and wind) makes “these two technologies the cheapest ways of producing electricity in many countries during the 2020s and in most of the world in the 2030s.”
Here is an interesting — though already out-of-date — chart of the decline in the price per kilowatt-hour of utility-scale solar power (as opposed to the charts above of the price per kilo-watt of the solar cells). It is based on U.S. Power Purchase Agreements (PPAs), which are contracts to sell electricity at a guaranteed price. It comes from a May 2015 Lawrence Berkeley National Laboratory study, “Is $50/MWh [5 cents/kwh] Solar for Real? Falling Project Prices and Rising Capacity Factors Drive Utility-Scale PV Toward Economic Competitiveness.”
CREDIT: LBNL, 2015[img][/img]
It illustrates the plummeting prices utilities have to pay for large-scale solar. But while the study is only a year old, it’s already out of date. For instance, Austin Energy has reported that last fall they they “signed on the dotted line for 288 MW of utility-scale solar power with First Solar Inc. and Hanwha Q CELLS USA Corp” with both offerings “coming in below 4 cents per kilowatt-hour” [below $40/MWh]!
This year we learned “City of Palo Alto considers solar power contract at under $37/MWh.” Bloomberg reported last week that “Berkshire Hathaway Inc.’s NV Energy agreed to pay 3.87 cents a kilowatt-hour for power from a 100-megawatt project that First Solar Inc. is developing.”
It is worth remembering that U.S. solar power bids include the 30 percent Investment Tax Credit. According to one analysis, NV Energy’s “$.0387/kWh would potentially turn into about $.07/kWh if we backed out the 30% Federal Tax Credit and 60% depreciation in Year One.”
The bids seen around the world this year without subsidies or incentives are even more stunning. Dubai Electricity and Water Authority (DEWA) received a bid this year for 800 megawatts at a jaw-dropping “US 2.99 cents per kilowatt hour.” Two other bids were below US 4 cents/kWh, and the last two bids were both below 4.5 cents/kWh — again all of these bids were without subsidies!
That 2.99 cents bid is way down from a 2015 deal Dubai signed for more than 1000 megawatts at 5.84 cents over 25 years. So Dubai has seen a 50 percent price drop in solar in just 18 months.
And these prices aren’t unique to the Middle East. As Bloomberg New Energy Finance reported in April, Enel Green power signed a contract for $.036/kWh in in Mexico — 3.6 cents.
With prices dropping so fast, sales of solar PV systems have been soaring, as you can imagine. Here is the recent growth in this country:
ANNUAL U.S. SOLAR PV INSTALLATIONS in Megawatts (2000-2015)
From 2005 through 2015, annual PV sales in this country went up 100-fold! And projections suggest that solar sales may double this year, driven by Congress’s five-year renewal (with phase-out) of the solar Investment Tax Credit (ITC).
And here is what the recent solar boom looks like world-wide — cumulative installed PV capacity and annual additions — from the recent “Renewables 2016 Global Status Report” by REN21, the Renewable Energy Policy Network for the 21st Century:
CREDIT: REN21
The solar miracle has been driven by major state, national, and international policies. BNEF Chair Liebreich calls this “The March of the Price Signal” — the rapid expansion of global deployment programs, especially market-based mechanisms such as renewable portfolio standards and reverse auctions.
Unfortunately, other countries have had bigger and more reliable deployment programs whereas our erratic policies generally diminish or disappear whenever and wherever conservatives assume control. In the past decade in particular, massive government-led deployment policies in China and Germany have been a major driver of the world’s stunning price drop.
The result is that while the United States invented the modern solar photovoltaic cell over a half-century ago, as of 2015, we are fourth in installed capacity worldwide:
CREDIT: REN21
The good news is that solar power in this country has a very bright future, thanks to the renewal of the ITC. By one recent projection, the U.S. could hit 100 gigawatts total installed capacity by 2021. That said, India also plans to hit 100 gigawatts by 2022.
China, however, plans to triple solar PV capacity to 150 gigawatts installed by 2020! So the race is definitely on.
No wonder the International Energy Agency concluded last fall: “Driven by continued policy support, renewables account for half of additional global generation, overtaking coal around 2030 to become the largest power source.”
The ‘Other’ Form Of Solar Energy, Which Can Run At Night
Earlier this month, I wrote about the “other” form of solar, concentrating solar thermal power, which uses sunlight to heat water and uses the steam to drive a turbine and generator. That heat can be stored over 20 times more cheaply than electricity — and much more efficiently — so CSP can provide power long after the sun has gone down.
For the sake of having all the solar charts in one place, here’s CSP capacity over the past decade:
CREDIT: REN21
Now that China appears to be placing a large bet on solar thermal electric, it seems likely CSP will also start coming down the learning curve, which will help it increase sales, which in turn will keep it coming down the learning curve — a virtuous circle that PV is already benefiting from.
The 2014 STE Technology Roadmap from the International Energy Agency (IEA) projected that while PV could generate 16 percent of the world’s electricity by 2050, as much as 11 percent could be generated by STE at the same time.
Given how fast solar PV has been coming down in price — and given the world’s commitment in Paris last December to keep ratcheting down carbon pollution in the coming decades to keep total global warming “well below 2°C” — it seems entirely possible if not likely that solar power will outperform the IEA’s scenario.
Indeed, it’s precisely because clean energy has been moving at the speed of light that “almost everything you know about climate change solutions is probably outdated,” as I’ve been detailing for months. Stay tuned to this channel for more surprises.
Obama announces plans to increase solar energy to low-income households
By Allen Cone | Updated July 20, 2016 at 12:57 AM
President Barack Obama announced plans Tuesday to increase solar energy in homes. File photo by Craig Russell/Shutterstock
WASHINGTON, July 19 (UPI) -- President Barack Obama announced plans to bring more solar energy to American homes, with a focus on a 10-times increase on the alternative energy for low- and moderate-income households.
The Clean Energy Savings For All initiative will expand the use of solar power with new programs to help reduce solar energy costs for consumers.
"Solar panels are no longer for wealthy folks who live where the sun shines every day," Obama said in a video with the announcement. "Today we're offering even more families and communities the chance to choose cleaner sources of energy that save you money and protect the planet for all of us."
Obama noted that solar usage has increased 30 fold since he took office and the number of jobs in the solar industry is increasing 12 times faster than in the rest of the economy.
But the 1 million U.S. homes with solar, according to the Solar Energy Industries Association, is about one-quarter of the 1-gigawatt goal than Obama wants installed by 2020 in low-income homes alone. That would amount to a 10-fold increase in the low- and moderate-income homes. Originally, Obama sought 100 megawatts of renewable energy for federally assisted families by 2020.
Housing authorities in 36 states have agreed to invest $287 million to help finance 280 megawatts of solar energy projects in low and moderate-income communities, Obama said. Including past commitments, this amounts to a total investment of $800 million.
The Clean Energy Savings For All initiative will expand the use of solar energy with new programs to help reduce solar energy costs for consumers.
Six federal agencies will participate in the initiative. They include the Department of Housing and Urban Development and the Department of Veterans Affairs to expand financing for rooftop systems and energy efficiency upgrades through lower property tax bills. The Energy Department will award $100,000 in cash prizes to communities developing solar farms for people who don't own their homes and to train solar workers in low-income neighborhoods. The Department of Agriculture, Environmental Protection Agency, DOE and HUD will help households and businesses that don't have adequate roof space to install solar systems -- especially in low- and moderate-income communities. Health and Human Services and DOE will provide technical assistance to low-income households for low-cost energy efficiency improvements, including renewable energy.
The government is also partnering with Google in expanding its solar mapping technology, Project Sunroof. "It leverages the 3D rooftop geometry data behind Google Earth to calculate the solar potential and financial benefits of solar power for 43 million American buildings across 42 states," the government release said.
New 3D solar cells capture sunlight from every angle
http://inhabitat.com/new-3-d-solar-cells-hitched-a-ride-to-space-for-testing/
Georgia Tech scientists developed three-dimensional solar cells which just hitched a ride to space this week on a SpaceX rocket. At the International Space Station, the solar cells will be tested to see how well they function and how they respond to space conditions. The solar cells have been designed to capture the sun’s rays from every angle, which could enable spacecraft to gain more power from a limited surface area.
The experimental module blasted into space includes four different types of solar cells. One type is a “traditional planar” solar cell, and a second is a planar cell based on a formulation of low-cost materials: copper-zinc-tin-sulfide (CZTS). These materials cost about “a thousand times less than the rare-earth elements” like selenium and indium used in some solar cells. There are also two types of 3-D solar cells: one “based on CZTS” and the other “based on conventional cadmium telluride.” There are 18 solar cells total, and they will be tested in space for six months.
Related: 2,500 orbiting solar “flying carpets” could power the planet
3-D solar cells could forever alter the way spacecrafts receive power. The Georgia Tech solar cells are described as miniature “towers” coated with a “photo-absorber.” Instead of requiring the sun to be right above them to work, the innovative 3-D solar cells can capture sunlight over longer periods of time. Georgia Tech Research Institute principal research engineer Jud Ready said in a press release, “We want to see both the light-trapping performance of our 3-D solar cells and how they are going to respond to the harshness of space.”
After six months, the solar cells will return to Earth so scientists can study how they held up in space. According to Ready, “If it can survive in space, which is the harshest of environments from the standpoint of wide temperature swings, radiation, and numerous other factors, then we can be confident it will work well down on Earth.”

Solar energy will be mainstream by 2020, says new report
Éanna Kelly, Science|Business
Analysis predicts the cost of solar cells is to fall dramatically over next five years but the loss of subsidies will be a setback for the technology in Europe
http://www.sciencebusiness.net/news/79878/Solar-energy-will-be-mainstream-by-2020-says-new-report
Solar power is reaching maturity as a global energy source, with solar power systems for both residential and utilities in line to reach grid parity by 2020, at which point the cost of electricity generated by the sun will be the same as that from other sources, according to new research from industry analysts Frost & Sullivan.
“Pro-solar incentives and the recently made pledges at the COP 21 summit will ensure that the market for solar [photovoltaic cells] continues to grow exponentially over the next five years,” said Frost & Sullivan energy and environment research analyst Pritil Gunjan.
Raw material suppliers, solar cell manufacturers, solar module manufacturers, and equipment suppliers and installers are all positioned to benefit, says the report.
The growth will happen mainly in China, India and Japan, which together will account for more than 80 per cent of all solar installations planned over the next five years.
It will be a less prosperous period for Europe’s solar industry which, “will suffer a setback due to withdrawal of subsidies and incentives,” the analysis says.
Huge overcapacity, coupled with a fall in the price of solar components, will see European suppliers struggling to turn a profit.
By contrast, solar panel manufactures will see strong growth in North America, largely thanks to the extension of investment tax credit eligibility for solar generators until 2019.
Solar panel revenues stood at $113.75 billion in 2015 and will grow to $179.13 billion in 2020.

A view of some of the 749,088 solar panels at the California Valley Solar Farm near Santa Margarita, Calif., in San Luis Obispo County, on Fri. August 28, 2015.
The same clear, sunny weather that broiled much of California in near triple-digit heat this week also helped the state’s solar power plants set a record, briefly generating enough electricity for more than 6 million homes.
Big Data Center Company Sues Nevada Regulators, Utility Over Solar Deal

It’s the latest dispute in Nevada over solar.
The owner of some of the world’s largest data centers has sued Nevada regulators and that state’s utility over a solar energy deal that it says led to it being overcharged.
Las Vegas-based data center operator Switch filed a lawsuit this week that alleges that its agreement to buy solar power, partly brokered by the Nevada Public Utilities Commission and utility NV Energy, was unfair, overpriced, and that employees of the state regulator acted inappropriately. The suit, which asks for $30 million in damages, claims fraud, negligence, and conspiracy.
The lawsuit is the latest dispute that has emerged involving solar energy in Nevada, a state with ample sunshine that was an early clean energy supporter.
As companies and residents in Nevada increasingly install solar panels, and sometimes unplug from the power grid, the state regulator and NV Energy are trying to figure out how to manage. The utility and the regulator have repeatedly clashed with both companies selling solar panels and customers buying solar panels.
NV Energy is owned by Warren Buffett’s Berkshire Hathaway.
Switch, along with some of the world’s largest Internet companies like Google GOOG 0.55% and Apple AAPL 1.98% , have increasingly sought to buy solar and wind power to operate data centers as a way to manage energy costs and be more environmentally friendly.
Switch, which has two massive data centers in Nevada, says it started trying to buy solar power from NV Energy in 2011. Its data centers, which sell services to eBay, Zappos and Cisco, are power-hungry facilities that are filled with computers.
Switch says NV Energy ignored its requests to buy solar power, prompting it to file an application in 2014 to disconnect from the grid so that it could seek solar power from other sources like First Solar FLSR 0.00% .
In the summer of 2015, Switch says the Nevada Public Utilities Commission denied its application to leave the grid. The regulator found that because Switch was such a large power customer, leaving the grid would financially hurt NV Energy and force it to raise rates and thus harm other power customers.
Instead, regulators said that Switch could buy solar power for a higher price through a deal with First Solar, but with NV Energy as the middleman. Switch says it agreed to the deal because it felt like it had no other options, and because an important federal solar subsidy was set to expire by the end of the year that would have driven up solar prices even more (the federal subsidy ended up getting extended).
First Solar is now installing 180 megawatts of solar panels as part of a deal to sell the power to Switch. That’s enough energy to run close to 30,000 average American homes.
Following Switch’s solar deal, the regulator later allowed several large Las Vegas casinos to disconnect from the power grid, with the agreement that the casinos would have to pay hefty fees to NV Energy to leave.
Switch says the solar deal it agreed to was an unlawful attempt to “retain Switch as a customer of the monopoly NV Energy.” Switch also says that the NPUC’s attorney, Carolyn Tanner, acted inappropriately by discussing the case on social media using a pseudonym.
The NPUC said it has yet to receive service of the complaint and therefore has no comment at this time.
