There is one problem with solar panels that I know of, not every home can have one. Examples: Our house can't have one after a few opinions say that the solar panels aren't designed for our roof, we tried to put solar panels in. And my relative, she wanted to have solar panels at her new house just like at her old one and her roof was eligible have solar panels put in. But the city denied it, however she was allowed to have one for her electric fence just not at her house. That wasn't a big deal at first since her electric bills was still cheaper than at her old house which was one of the reasons why she moved there, unfortunately one of her power plants just shut down recently and now her bills has started to rise. She also lives in a area where the power would go out quite often which doesn't help the problem. Luckily she has a generator that runs on natural gas but it doesn't power up everything in the house.
Also on a side note, I'm not buying that "free solar" claim in the picture. These are scams, it’s basically just a really bad loan that these guys are offering, it is not free. There is no such thing as free solar.
