Types of Batteries for Solar Power Storage

Batteries for solar power store the excess energy from your solar panels for use after the sun goes down or at times when your electrical loads are drawing out more than the panels are putting in.

You’ll have to choose between deep-cycle batteries, golf cart batteries, sealed (or not) batteries, lead-acid batteries, absorbed glass mat sealed lead acid (AGM) batteries, gelled electrolyte sealed lead acid (GEL) batteries, and a few others that aren’t so well known. Each one has strengths and weaknesses. For the most part you’ll get what you pay for, so make your choice wisely.
