Is going solar in San Leandro still a smart financial move in 2026? With high PG&E electricity rates, the potential for savings remains strong. However, the end of the federal tax credit for homeowners and California's new net billing rules mean the approach has changed. Success now hinges on maximizing the use of your own solar power, often with the help of a home battery, rather than just selling excess energy back to the grid.
This guide breaks down the current costs, savings, and payback period for a typical San Leandro home, helping you decide if the investment makes sense for you.

Estimated 2026 Solar Costs in San Leandro
For an average home in San Leandro, a 5.1 kW solar system can offset a large portion of the monthly PG&E bill. Here are the modeled costs for 2026, keeping in mind that the federal tax credit is no longer available for new residential systems.
- Solar-Only System (5.1 kW): The estimated upfront cost is $13,005.
- Solar + Battery System (5.1 kW panels, 10 kWh battery): The estimated total cost is $28,005.
The battery adds to the initial price, but it's recommended to increase your energy independence and unlock greater long-term savings under PG&E's current rate structure.
Incentives & Tax Credits
California's Ongoing Solar Benefit: No Property Tax Increase
Even without a federal tax credit, California homeowners have a significant advantage. The state's property tax exclusion for active solar systems means your property taxes won't go up after you install solar panels.
This is a powerful incentive that ensures the value added to your home doesn't result in a higher tax burden. An owned solar system can also be an attractive feature for future buyers, potentially enhancing your home's resale appeal without the associated tax penalty.

PG&E's Net Billing: Why Self-Consumption is Key
Homes in San Leandro with solar fall under PG&E's Net Billing Tariff (NBT). It's crucial to understand this isn't old-school net metering. The value of your solar energy depends on when you use it:
- High Value: When your solar panels power your home directly, you avoid buying expensive electricity from PG&E (at ~$0.32/kWh).
- Low Value: When you produce more power than you need and export it to the grid, PG&E credits you at a much lower rate (modeled at ~$0.11/kWh).
This system is designed to encourage homeowners to use their own power. A battery helps you achieve this by storing your cheap, clean solar energy produced during the day for you to use during the expensive evening hours.
Projected Savings
How Much Can You Save on Your PG&E Bill?
Your total savings depend on how much of your own solar energy you use directly. Because exporting power to the grid provides a low credit, using or storing your solar power is the best way to reduce your PG&E bill.
- A solar-only system is modeled to save approximately $1,490 annually, with an estimated payback of 8.0 years.
- Pairing that system with a battery increases the estimated annual savings to $2,165. The payback period extends to 10.1 years, but you save over $600 more each year.
Beyond the direct bill savings, a battery also provides valuable backup power, a key benefit for households concerned about grid stability and potential outages in the Bay Area.
