@BetoOnSecurity Backup power is fairly straightforward. You don't need to power your whole house (although that is nice). Small, independent (non-house) solar + battery is good enough to charge phones, keep the radios fired up, charge a laptop, keep some lights on at night. Heck, enough to run the TV and satellite receiver for entertainment. But, the challenge is when you start talking about refrigerator/freezer/air conditioner.
