Go solar – residential
Battery Backup
Looking for a reliable way to keep the lights on during a power outage? A solar battery backup system lets you store excess solar energy and use it when you need it most. Ecotech Solar offers the best solar battery backup systems for home use, including trusted options from Tesla, Enphase, and FranklinWH.
Backup Power for Medical Devices
You could save up to $10,000 on a backup battery system.
Many people rely on electricity to operate oxygen concentrators, dialysis equipment, ventilators, refrigerated medications, infusion pumps, and more. A home battery backup system keeps essential equipment running automatically during power outages. Puget Sound Energy offers significant incentives that may reduce the cost of a home battery system by thousands of dollars.
The grid power goes out in our area quite frequently
“Peace of mind is the biggest benefit…most of the time, we aren’t even aware the power grid went out until we get a message from PSE.”

Why Add Solar Plus a Battery Backup System?
A battery backup system gives you peace of mind and energy independence. While standard solar panels shut down during outages, adding a battery means your home stays powered even when the grid goes down.
Benefits of a Solar Battery Backup System:
- ^Power your home during grid outages
- ^Use more of your own solar energy
- ^Lower electric bills with time-of-use savings
- ^Reduce reliance on the utility
- ^Quiet, clean, and fully automatic
- ^Seamless integration with new or existing solar systems
Battery backup vs. a Generator
Unlike gas generators, solar battery backup systems are:
- Silent – no engine noise
- Fume Free – safe for indoor use, no emissions
- Automatic – kicks in instantly when the power goes out
- Low maintenance – no fuel refills or engine upkeep
- Smart – manage energy use with a mobile app
