Home Battery Storage

Pairing solar panels with a home battery lets you store excess energy for use at night, during outages, or when electricity rates peak. Battery storage maximizes your solar investment by reducing grid dependence and providing backup power when you need it most. Compare the top residential battery systems for 2026 below.

Why Add Battery Storage?

Backup Power

Keep your lights on, refrigerator running, and essential devices charged during grid outages. A fully charged battery can power critical loads for 8-12+ hours.

Energy Independence

Reduce your reliance on the utility grid by storing daytime solar production for evening use. In Hawaii and California, this is especially valuable due to time-of-use rate structures.

Maximize Savings

In states without full net metering, batteries let you use more of your own solar energy instead of selling it back at lower buyback rates, increasing your overall savings.
