Tesla Powerwall Solar Battery BackupWhat Is a Solar Battery? 

Solar panels produce a lot of electricity during peak sunlight hours — usually, more than you need to power your home. In a traditional grid-tied residential solar PV system, any excess energy you don’t use that’s produced during the day is sent back to the grid. When you have a solar battery storage system, the solar batteries are charged by the surplus electricity for later use in your home.  

Solar batteries provide you with a backup power source that you can tap into at night, during peak demand periods, a power outage like a Public Safety Power Shutoff, or when you receive a flex power alert. Solar panels alone won’t keep your lights on when the grid is down because they are automatically switched off to protect utility workers while repairing the grid. 

Home solar battery storage systems come in many different sizes and configurations. We can help you choose the best battery system for your home and determine how many batteries are needed. Our team will talk to you about what your energy needs are now and how they may change in the future.

What Are the Benefits of Solar Batteries with a PV System? 

A home battery backup system will help you get the most out of your investment in solar panels by increasing your resiliency and mitigating risks, especially during wildfire season in Northern California. Here are a few of the many reasons why you should have a solar power battery backup for your home in California:

  • Power during rotating outages, rolling blackouts, and PSPS events
  • Charging when rates are low to avoid Time-of-Use or peak demand rates
  • Greater energy independence: your power when you need it most
  • Smaller carbon footprint and lower greenhouse gas emissions
