Make better use of your solar energy with a home battery backup system. Store extra electricity during the day and use it at night, during peak-rate hours, or when the power goes out. GT Power helps homeowners in Concord, Contra Costa County, and surrounding California communities explore solar battery storage options based on their energy needs, existing solar system, and backup priorities. A properly configured battery can keep selected household essentials running when grid power is unavailable.
Solar panels generate electricity during the day, but your home still needs power after sunset. A solar battery stores extra energy for later, helping you use more of the electricity your panels produce instead of relying entirely on the grid.
Power outages can disrupt everyday life, from keeping food cold to staying connected with family. With a properly designed home battery backup system, you can keep essential appliances, lights, and devices running during an outage. The amount of backup power available depends on the battery capacity, your household energy demand, and the circuits connected to the system. A home battery can also reduce reliance on the electrical grid by storing excess energy and supplying it when household demand is higher.
For California homeowners, solar battery storage can help manage electricity costs by storing daytime solar energy for use later. For customers of PG&E, SCE, and SDG&E, California’s Net Billing Tariff (NBT) is referred to by the utilities as the Solar Billing Plan. Under this structure, the value of electricity imported from or exported to the grid can vary by time of day, making battery storage especially useful for shifting solar energy to higher-cost evening hours. Specific rates, peak periods, and billing rules vary by utility and rate plan, so GT Power can help you explore battery options based on your energy use, utility, budget, and backup needs.

A home solar battery backup system helps you make the most of your solar investment. Store extra daytime energy for nighttime use, reduce electricity purchases during peak-rate hours, and maintain power for selected household essentials during outages. Battery storage can also help you rely more on your own solar energy instead of purchasing as much electricity from the grid. Whether you want to keep your refrigerator running, charge your devices, or manage rising electricity costs, a properly sized system offers greater control over how your home uses energy.
Eligible California homeowners may qualify for incentives through the Self-Generation Incentive Program (SGIP), subject to current program rules and available funding. SGIP’s current Residential Solar and Storage Equity program provides incentives for qualifying low-income households installing paired solar and battery storage systems. GT Power can help you explore battery options, including Enphase and Tesla Powerwall, based on your home’s energy needs, budget, and backup goals.
