The short version

A solar battery, in one page.

What one costs, how the rebates stack, which brands hold up, and whether it's worth it for your home. The full detail lives in the guides linked below.

A solar battery stores the power your rooftop solar panels make during the day, so you can run your home on it after dark instead of buying electricity back at peak rates. Whether you're searching for a solar battery, a solar panel battery, or simply a battery for your solar panels, it does the same job: it turns free daytime sun into usable evening power. This page pulls together what one costs, which brands are worth a look, whether it pays off, what installation day looks like, and your state's separate rebate on top of the federal discount.
