High electricity bills from San Diego Gas & Electric are a common challenge for homeowners in Laguna Niguel, with rates around $0.323 per kWh. While solar panels generate significant power in Orange County's strong sun, the rules for selling surplus energy back to the grid have changed. In 2026, the value of rooftop solar is increasingly about how much energy you can use yourself, making the addition of a home battery a critical part of the conversation.

Estimated Solar System Costs in Laguna Niguel (2026)
For a typical home in Laguna Niguel, a 7.2 kW solar panel system is sized to offset a significant portion of the average electricity bill. The estimated gross cost for this system is $18,360.
Pairing this system with a 10 kWh battery for energy storage increases the total cost. The combined solar and battery system has an estimated gross cost of $33,360. These figures are estimates before any local incentives and reflect the market now that the 30% federal tax credit for homeowners is no longer available for systems installed in 2026.
Incentives & Tax Credits
California Solar Incentives for 2026
With the federal residential solar tax credit no longer in effect, California homeowners rely on important state-level benefits to support their investment:
- Property Tax Exclusion: In California, installing a solar system will not increase your property taxes. The added value of the solar installation is excluded from your home's valuation for tax purposes, a benefit available for systems installed through at least mid-2026.
- High Rate Avoidance: The primary financial driver for solar in California is avoiding some of the highest electricity rates in the country. Every kilowatt-hour of solar energy you use at home is a kilowatt-hour you don't have to buy from SDG&E.
An owned solar system can also be a significant long-term feature, potentially supporting your home's resale appeal to future buyers looking for lower utility bills.
Net Metering: San Diego Gas & Electric Co
Net Billing (low export)

Understanding Export Rates with SDG&E's Net Billing
Laguna Niguel homeowners connect to the grid under a policy often called a Net Billing Tariff. This is different from older net metering programs. Instead of a one-to-one credit, any surplus solar energy you send to the grid is purchased by the utility at a rate based on its 'avoided cost' — which is much lower than the retail price.
This structure is why a battery is highly recommended. By storing your excess solar power, you can use it yourself later when the sun goes down, maximizing your savings and reducing your reliance on exporting power for a low credit.
Projected Savings
How Solar and Battery Storage Impact Your SDG&E Bill
Under current SDG&E rules, the electricity you export to the grid is credited at a much lower rate (modeled here at $0.113/kWh) than the retail price you pay for electricity ($0.323/kWh). This makes self-consumption the most effective way to save.
- A solar-only system (7.2 kW) is modeled to generate approximately $2,216 in annual savings, with a payback period of about 7.6 years.
- A solar and battery system significantly increases self-consumption by storing excess daytime solar energy for use during evening peak hours. This configuration boosts the modeled annual savings to $3,308, with a payback period of around 8.3 years.
While the upfront cost is higher, the battery adds over $1,000 in additional annual savings by helping you avoid purchasing expensive evening power from the grid. Furthermore, if grid electricity becomes more expensive over time, rooftop generation can offset costlier power in future years, making your investment even more valuable.
