I have used solar panels a couple times. When hiking in Alaska we were 50 miles from any power and gas generators not allowed. I had a portable solar panel I used to charge up batteries to keep my phone, GPS, and sat phone charged. At farm in Oklahoma we put solar panels on the hay barn. Unfortunelty Oklahoma not good about paying for the power, but will credit your account back to zero every month. Power company not easy to work with, they hate customers with solar! We're waiting to see how home battery technology evolves, we would like to do that eventually.
