A single Tesla Powerwall provides 13.5 kilowatt-hours (kWh) of usable storage capacity, which is enough to power essential appliances like lights, refrigerators, and Wi-Fi routers for several hours during an outage. Multiple Powerwall units can be combined to increase total storage for larger homes or higher energy needs. Sun Solar also offers the SunPower SunVault storage system, which provides high-capacity storage with efficient energy management.

Sun Solar offers solar-plus-battery storage packages starting at $99 per month with flexible financing options, including low-interest and $0-down loans. The total cost depends on the number of battery units, your home's energy usage, and available incentives. California homeowners may qualify for the federal solar Investment Tax Credit (ITC) and local rebates that reduce the overall cost. Adding battery storage can save $20 to $30 more per month on your electric bill compared to solar alone.

Home battery storage systems like the Tesla Powerwall are designed to last 10 or more years with proper care. They require minimal maintenance because there are no electrolyte checks, fuel refills, or moving parts. The battery operates quietly and recharges automatically using your solar panels during the day, so it is ready whenever you need backup power at night or during a grid outage.

Yes. California homeowners can take advantage of the federal Investment Tax Credit (ITC), which applies to battery storage systems installed alongside solar panels. California also offers the Self-Generation Incentive Program (SGIP), which provides rebates for qualifying battery installations. Property tax exemptions may apply as well, since adding a battery system does not increase your property tax assessment. Sun Solar can help you identify every incentive you qualify for.
