With some of the highest electricity rates in the country from San Diego Gas & Electric (SDG&E), many San Clemente homeowners are looking for ways to control their energy costs. In 2026, rooftop solar paired with battery storage offers a powerful solution. By generating and storing your own electricity, you can drastically reduce your reliance on the grid, protect yourself from future rate hikes, and gain energy independence during outages.

2026 Solar Installation Costs in San Clemente
Investing in a solar system is a long-term strategy for managing energy costs. Here are the estimated upfront costs for a typical home in San Clemente, based on a 7.6 kW system size:
- Solar-Only System: The estimated gross cost is $19,380.
- Solar + Battery System: The recommended package has an estimated gross cost of $34,380.
While the initial cost is higher with a battery, the significantly increased annual savings and faster payback make it a compelling financial choice for most homeowners under current SDG&E rules. An owned solar system can also be a useful long-term home-value feature for potential buyers.
Incentives & Tax Credits
Key California Incentive: Property Tax Exclusion
As of 2026, the primary state-level incentive supporting solar adoption in San Clemente is the property tax exclusion for active solar systems. This valuable benefit means that when you install a solar system, its added value to your home is excluded from your property tax assessment.
You get the benefit of lower energy bills and a potentially more attractive home for resale, all without an increase in your property taxes. While major tax credits are no longer the main driver, this exclusion, combined with substantial bill savings, keeps solar a strong financial decision.

How SDG&E's Net Billing Rules Affect Solar Value
San Clemente is in SDG&E territory, which operates under California's Net Billing Tariff (NBT). This means there's a big difference between the price you pay for electricity and the credit you get for exporting your excess solar power.
You might pay over 32 cents per kWh to pull power from the grid, but you'll only receive a credit of around 11 cents per kWh for the solar energy you send back. This structure makes it clear: the most valuable solar energy is the energy you use yourself. A battery ensures you can use your own clean power around the clock, rather than selling it cheap and buying it back expensive.
Projected Savings
Potential Savings with Solar in San Clemente
The financial benefits of going solar are directly tied to how much expensive SDG&E power you can avoid buying. With California's current net billing rules, pairing solar panels with a battery unlocks the most significant savings.
- A 7.6 kW solar system with a 10 kWh battery is the recommended path. This setup is modeled to generate annual savings of approximately $3,308, with an estimated payback period of just 8.6 years.
- For comparison, a solar-only system would save around $2,216 annually, with a payback of about 8.0 years.
The battery adds substantial value by storing solar energy produced during the day for you to use during the evening, when SDG&E's rates are highest. This strategy of self-consumption is key to maximizing your return on investment.
