That's a good read. The solar panel system I had in Illinois actually made more power than I used. My system was hooked directly to the grid and the meter monitored how much electric was being used as well as how much power I was making. My electric usage fees were zero but I still had to pay operational costs to maintain the grid so my bill was always 20$ a month.
Some systems have an optional battery backup to store power for outages but mine didn't. In the 30 years I lived there, there was only a handful of outages and they were usually short lived. One time we went without for 20 hours or so but considering the damage that the storm created nearby me, we did really well.
I also have 3 gas generators that can make power in a pinch like that so a battery backup wasn't economically feasible because the batteries aren't cheap. They cost close to what the panels did and it made no sense to pay that much for something I didn't need.
As the idea matures, I think we'll see a lot more of them on top of single family homes. It really is a no brainer if you're planning on staying for an extended period of time because the panels pay for themselves after a few years. My run in Illinois was cut short only having them for two years before moving but they added at least 10K to the resale value of the house. The system is paid off, the new owners get to enjoy their 20 dollar a month bill for power and I broke out just about even on the deal.
I'm looking into them for the place in TN now but there's other things I need to take care of first before we get to all that.
LOL I didn't get my dispensary job so it's been back to plan A, studying the international and local building codes so I can pass my exams and get my building inspectors license. 🧐
