Solar Energy Storage for California Homes

Updated: Jul 28, 2023

As California strives for 100% clean energy by 2045, more solar system homeowners are considering adding solar energy storage. By storing excess solar energy during the day, homeowners can use that power at night or during high-demand times instead of relying on the utility company. According to the California Public Utilities Commission (CPUC), using solar panels alone can save customers around $100 per month, while those with storage can save up to $140 per month. The savings are projected to offset the solar and storage system costs within seven years.

Let's explore the benefits of solar energy storage for California homeowners and how it can provide increased energy independence and emergency backup power.

Benefits of Incorporating Solar Battery Storage into CA Solar Energy Systems

Energy Independence and Reduced Grid Reliance

Integrating energy storage systems allows surplus energy to be stored in high-capacity lithium batteries, promoting true energy independence by reducing reliance on non-renewable sources.

For instance, if your system generates 10 kWh daily but usage is a mere 5 kWh, storing the extra 5 kWh in batteries enables you to utilize it later and reduces reliance on utility providers such as PG&E, SCE, and SDG&E, thus lowering overall energy expenses.

Emergency Backup Power

If the grid goes down, a resident of the Greater Coachella Valley or Greater Fresno can still have power if energy (kWh) is produced and your battery bank is charged. Battery storage systems are vital during natural disasters or power shut-offs.

Do you remember the horrible 2020 California wildfires? Power outages lasted for weeks, causing distress. But homeowners with backup power could keep their homes illuminated, refrigerators running, and devices charged.

Energy storage lowers electricity bills

Lower Electricity Bills

Solar power and energy storage are great ways to reduce hefty energy bills. A Southern California homeowner installed a 5 kW solar system with energy storage, resulting in a 90% reduction in energy bills by using stored solar energy during peak hours when utility rates are highest.

Boosted Energy Efficiency

Energy storage offers additional flexibility in energy usage, enabling generated energy consumption at different times of the day. An excellent energy storage system, in turn, heightens the efficiency and resilience of energy systems and provides an improved power quality that aligns supply and demand.

Self-Generation Incentive Program (SGIP) for Energy Storage Systems BY CPUC

The California Public Utilities Commission initiated the SGIP program to offer a massive REBATE as reimbursement for battery storage for solar systems on residential and non-residential properties.

A single-family may receive an $850/kWh rebate under the Equity Category, while a small business may receive $1,000/kWh in the Equity Resilience Category. Both SGIP rebate categories can potentially offset 85% and 100% energy storage costs, respectively.

Who can benefit?

  • All CA residents, including those in the Greater Coachella Valley and Fresno Areas

  • Low-income and medically vulnerable homeowners

  • A government agency, educational institution, non-profit, or small business (grocery store, supermarket, etc.)

  • Customers of investor-owned utilities (IOUs)

  • High fire-threat area or multiple Public Safety Power Shutoff (PSPS) communities

  • Critical facilities for PSPS or wildfire resilience

  • Community Choice Aggregators (CCAs)

Customers must meet various criteria to be eligible for SGIP rebates. Please check the Brochures and Fact Sheets for detailed information about eligibility, and contact your Program Administrator with questions. You can find more information on the website here.

Factors Affecting the Installation of Solar Energy and Storage Backup Systems in CA Homes

  • Home energy consumption (kWh)

  • Installed solar system size

  • Battery capacity (Ah)

  • Battery type (lead acid or high-efficiency lithium batteries)

  • Climate and weather conditions

  • Rebates and incentives

High-efficiency lithium batteries are better suited for CA residential solar energy storage systems due to their efficiency, durability, and ability to adjust to the wide temperature variance in the State.

Will I still have to pay for electricity if I have a solar energy storage system?

The answer is not straightforward; it depends on the size and capacity of the solar energy system, the household electrical load, and local regulations.

Say a family of four lives in a home with a 7 kW solar panel system and battery storage. Their solar panels generate 35 kWh daily, enough to power their home during the day and charge the battery. During peak hours, the battery discharge may not provide enough electricity to fully power the house, so they may need to draw grid electricity. If they use around 40 kWh daily, they would pay the utility for the difference between what their system produces and what they need - 5 kWh.
