solar for backup power
I'm going to be upfront about something: this section is not about solar for saving money on your electric bill. That's a valid reason to go solar, but it's a different conversation with different math.
This is about solar as part of a backup power system. Solar panels paired with battery storage that keeps your house running when the grid goes down. Solar as fuel that doesn't need a delivery truck, doesn't run out, and doesn't make noise.
I run a small solar array on my property. It's not my primary backup — that's a propane standby generator. But the solar keeps my batteries topped off during extended outages and means I'm burning less fuel. On a sunny day, the generator doesn't need to run at all.
Solar alone won't keep your house running during a multi-day winter outage. But solar paired with battery storage and a generator is the most resilient system you can build. It's also the most expensive. Start with a generator. Add solar when you can afford it.

Solar is the long game. A generator solves the problem today. Solar solves it permanently — but only if you pair it with enough battery storage to get through the night and the cloudy days. Most people should get a generator first, then add solar when they can. That's what I did, and I'd do it the same way again.
