But solar has its own issues - expensive solar panels (you'll pay tens or hundreds of times more for solar than for a generator), solar panels aren't worth having unless they are high quality and finding high quality solar panels is a pain, you can't craft the solar panels, each solar bank is 3 blocks long instead of the 1 block of a generator and you have to also include a battery bank to handle nights, which makes it 4 blocks versus 1, each solar bank only has about half the power of a generator, meaning you can need more banks than you'd need of generators. For an endgame item, it is kind of backwards. You normally get better stuff at endgame, but the negatives for solar make it not really worth getting unless you just like it or don't want to hear the generators or you don't want to have to keep refilling the fuel. Fuel itself is extremely cheap by the time you have a choice to get solar panels, so it's not really a cost savings to use solar, especially considering how much extra you pay for it to begin with. I would really like to see solar get some "love" so it's actually worth getting. I think most people don't use solar because of the negatives.
