The best reason to consider personal solar power is the ability to go off grid and be independent. Being a prepper might mean paying more for electricity. If your neighbor can run entirely on solar for $10k, it is a steal though.
Agreed. I suppose retro-fitting your “current” set up is a viable option if you can scrape up the money to do it. I have a pretty big chunk of open space on the south side of the house where panels could be placed but like a lot of folks, don’t have the $$$ to do it. Don’t want to take out a loan either. But, it would be nice to not have to pay NVEnergy every month. Lucky for us we have a “smart” meter to help keep us straight. LOL!
