Improved Efficiency with Solar Battery Storage

Battery Installation from Sunwell Solar for Storage and Backup

Installing solar batteries for your home can make a surprising difference in the efficiency of your system and the cost of your utility bills. A solar energy storage system stores excess electricity generated by the bright, southern California sun during the day and puts it to use after dark. You’ll be less reliant on the energy grid while taking full advantage of what your solar system has to offer. Contact us to learn more about how solar battery storage can benefit your home.

Battery Storage vs. Battery Backup—What’s the Difference?

Solar batteries can perform two major functions depending on how they are installed: energy storage and electrical system backup. At Sunwell Solar, we want to make certain homeowners get the right solution for their needs.

The Benefits of Solar Battery Installation

Whether you want to save more, stay prepared, or become energy-independent, Sunwell Solar’s battery installation services deliver real results.

  • Lower Utility Bills: Store the extra energy your solar panels produce and use it when utility rates are highest.
  • Maximize Your Solar Investment: Battery storage lets you use more of the clean power you generate, giving you better returns on your solar system.
  • Power During Outages: With battery backup, you won’t be left in the dark when the power goes out. Keep your lights on and appliances running during planned and unplanned outages.
  • Take Advantage of Solar Incentives: Solar batteries may qualify for incentives like the CPUC’s Self-Generation Incentive Program (SGIP), reducing your initial costs.

Christopher B.

The Sunwell Solar team did an amazing job setting up our home solar system. Friendly, courteous, and professional at every step from the initial site survey, to planning, and install. Clear and prompt communication throughout and addressed all of our concerns. We participated in the Solar Equity Program which required a lot of extra paperwork and forms and Sunwell was very organized and made it a breeze. We had an 18 panel system installed with a 225A main service panel upgrade. 5/5 amazing service! Will be using this company again in the future when we install a home battery backup and electric car charger.

Common Solar Battery Storage Questions

If you have questions about solar battery storage or backup systems, we’re happy to answer them.

Battery storage systems save excess solar energy for later use, helping you reduce your reliance on the grid and lower utility bills. Storage with backup, on the other hand, provides power during outages to keep essential appliances running when the grid goes down.

If your goal is to maximize solar savings and use more of your own energy, a storage system is ideal. If you’re more concerned about having reliable power during blackouts or emergencies, a battery backup system offers peace of mind. Sunwell Solar can help you decide which option fits your needs—or design a system that does both.

Yes! Sunwell Solar can install a battery that integrates with your current solar panels.

That depends on the battery’s capacity and your energy usage. Some systems can power your entire home, while others are designed to back up essential circuits like refrigerators, lighting, and medical devices. We’ll help you design a system that meets your backup needs.

The SGIP is a California rebate program that provides financial incentives for installing battery storage systems. Homeowners in San Diego County may be eligible for significant rebates through SGIP, depending on system size, usage, and income qualifications. Sunwell Solar can walk you through the application process to maximize your savings.

So long as your system has a capacity rating of 3kWh or greater, the project should qualify for the 30% solar tax credit.

Most solar batteries have a lifespan of 10 to 15 years, depending on the brand and how often they’re used. Premium brands like Tesla, Enphase, and FranklinWH are known for their long-lasting performance and warranties.
