Living in Poway means dealing with some of the highest electricity rates in the nation from San Diego Gas & Electric (SDG&E). For many homeowners, a monthly bill of nearly $300 is common. Rooftop solar presents a powerful way to reduce that expense, but success in 2026 depends on a smart strategy. With current utility rules, simply producing power isn't enough; you have to maximize using that power yourself to see the best financial returns.

What Do Solar Panels Cost in Poway in 2026?
After understanding the savings potential, it's important to look at the upfront investment. The costs below are estimates for a fully installed 7.1 kW system, sized for a typical Poway home.
- Solar Panels Only Cost: Approximately $18,105. This system has a modeled payback period of about 7.5 years.
- Solar Panels + Battery Cost: Approximately $33,105. While the initial investment is higher, this system provides greater savings and has a modeled payback of around 8.3 years.
The choice depends on your goals. The solar-plus-battery option delivers superior long-term savings and provides valuable backup power during grid outages, a growing concern for many Californians.
Incentives & Tax Credits
Key Financial Benefits for Poway Solar Owners
As of 2026, the federal tax credit for residential solar is no longer in effect. However, California provides a crucial incentive that makes the investment more manageable:
- Property Tax Exclusion for Active Solar Systems: When you install a rooftop solar system, its value is excluded from your property tax assessment. This means you get the benefit of a home improvement that saves you money every month without the downside of a higher property tax bill.
The main financial incentive remains the substantial reduction in your monthly SDG&E bill. By generating and storing your own power, you are effectively locking in a lower cost of energy for decades to come.

How SDG&E's Net Billing Affects Your Savings
Under the current net billing tariff, SDG&E compensates you far less for the extra solar energy you export to the grid than what they charge you for power you import from it.
- Import Rate: You pay SDG&E the full retail rate for electricity, which can be around $0.32 per kWh or more.
- Export Credit: When your system overproduces, the surplus energy sent to the grid might only earn you a credit of about $0.11 per kWh.
This gap between the purchase price and the export credit is why a battery is so highly recommended. Storing your own solar power is worth the full retail rate you avoid paying, making it nearly three times more valuable than exporting it.
Projected Savings
Projected Solar Savings on Your SDG&E Bill
The financial benefit of going solar in Poway is directly tied to how effectively you can avoid purchasing expensive electricity from the grid. Adding a battery to your system makes a significant difference in achieving this.
- A typical 7.1 kW solar-only system is estimated to save a Poway homeowner around $2,216 in the first year.
- By pairing that same system with a 10 kWh battery, the estimated first-year savings jump to $3,308.
Why the big difference? The battery allows you to store the free, clean energy you generate during the day and use it during the evening and nighttime hours, when SDG&E's rates are often highest. This strategy of self-consumption is key to getting the most value from your investment. Over the long term, an owned solar system also protects you from future SDG&E rate hikes and can be a compelling feature for future homebuyers.
