How to Keep Solar Batteries Warm in Winter

Sunlight doesn’t just power your solar panels – it heats your batteries. With fewer hours of sunlight per day, winter is the time of year when it’s most important to make sure the energy storage component of an off-grid solar power system or grid-tie solar system with battery backup is working efficiently. Unfortunately for those of us in the northern U.S. and Canada, winter can bring extreme cold, creating the worst environmental conditions for those deep-cycle batteries.

But just because deep cycle solar batteries have a harder time in cold temperatures doesn’t mean you need to suffer through the winter with them. Learning a few simple tricks to keep solar batteries warm in winter will substantially improve their performance during the part of the year in which you rely on them most.
