I think solar is great for those that can use it, my issue is it getting crammed down my thoat.
For use case our SAR Team has a 40' shipping contianer. This is divided into a 20' storage unit and a 20' classroom. Being we are volunteer and not funded a monthly electic bill isn't the best. We installed a 100 watt panel and some batteries. This year we got a grant to replace the 30 year old batteries. Doesn't cost us anything and is more than enough for a class, or to stop and grab gear at night.
I also have a shed on my property. NO AC power in it and only way is overhead due to concreate. I put a 20 watt solar panel, a 3ah battery and a LED strip light. On a motion detector. Perfect to go in grab a wrench or other tool and leave. It wont last 8 hours but fills a need.
On the other hand I could not run my house or want to. I wont be alive by the time I make my money back.
