Well that's is a very uneducated opinion. Solar panels work only during the day. And they don't even come close to produsing the same amount of electricity. A solar project to start would have to cost 5 billion dollars just in material to make the same amount of electricity. And they still can't sell electricity for less that .14 cents a kilowatt. Just try doing a little bit of research dude. And why would solar try to make it that much more efficient, besides it being impossible. In 10 years electricity will be around 14-16 cents anyways. So they also will make money.
