I've looked into going solar multiple times over the last 5 years, but I always conclude that the cost benefit isn't quite there yet. There is still battery tech emerging as well and thats the large part of the cost of a system.
It's been a financial net negative for sure but that was never the objective. What I wanted to achieve was: - Have a week+ of emergency power in a blackout situation. - Give as little as possible to the "power jews", as I like to call the suppliers.
I've weighed that in consideration as well, but for the time being I've settled for a generator. Next objective is to get and inlet port installed on my housr and buy a power station to avoid potentially having to run said generator overnight.
As of the time being power outages are very rare and only last 4-8 hours typically, although the last icestorm had me out for nearly 24 hours.
