Solar costs vs return. Got to see the figures for a solar system to effectively change your home to zero energy. Panels alone cost $70K, plus switch gear, etc, more like $85K. Based on the size of the home and average electric rate, savings was apprx $2500 per year. Given the probable life of the system, changes in technology, etc, probable life is less than 15 years.
Given that blackouts are very seldom, unless it really gets to be a problem, just live with them as they generally last for only a few hours. An inexpensive gas generator ($500 used) will do the job for some lights, refrigerator, etc. Get an UPS for the computer if not running a laptop.
If you are a survivalist, then that’s another story, but make your own solar generating system from the parts as opposed to buying one.
I paid a LOT less than that for my grid tied system.
I bought it years ago, and it’s pert near paid for itself by now.
Where did you get your numbers?
Cost depends on how much power you want and how much sun you get.
You can get a system which will run a few lights, and perhaps a small fridge for $4-5k.
