Is going solar in Campbell still a smart financial move in 2026? With some of the highest electricity rates in the nation from PG&E, reducing your utility bill is more important than ever. However, the rules have changed. The value of solar is no longer just about production, but about how you use that power. For many homeowners in Silicon Valley, the answer now involves pairing solar panels with battery storage to maximize savings and secure energy independence.

2026 Solar and Battery Costs in Campbell
Here’s a look at the estimated upfront investment for a typical solar installation in Campbell, based on a 6.5 kW system sized for an average local home. These costs for 2026 do not assume any federal tax credits are available for homeowners.
- Solar-Only System (6.5 kW): The estimated gross cost is $16,575. This system is designed to offset a large portion of your daytime energy use.
- Solar + Battery System (6.5 kW panels with a 10 kWh battery): The estimated combined cost is $31,575. This setup not only generates power but also stores it for use anytime, day or night.
While the solar-plus-battery option requires a larger initial investment, it unlocks greater long-term savings and provides critical backup power during grid outages.
Incentives & Tax Credits
Key California Solar Benefits in 2026
Even without a federal tax credit for residential systems installed in 2026, California homeowners have access to valuable state-level incentives.
- Property Tax Exclusion: Adding a solar system increases your home's value, but thanks to a statewide exclusion, it won't increase your property tax bill. This is a significant, direct benefit.
- Avoiding High PG&E Rates: The most powerful financial incentive is the ability to generate your own electricity and avoid paying PG&E's steep residential rates, which are projected to remain high.
- Local and Utility Programs: While not guaranteed, it's always worth checking for any specific battery rebate programs or other incentives that may be offered by PG&E or local initiatives.

How PG&E's Net Billing Affects Solar Savings
Campbell residents are in PG&E territory, which uses a net billing system. This is a critical detail for anyone considering solar.
Under this structure, the electricity you purchase from the grid costs significantly more (modeled at $0.323/kWh) than the credit you receive for exporting your excess solar energy (modeled at just $0.113/kWh). This price difference makes it financially disadvantageous to sell your solar power back to PG&E. The smartest strategy is to use or store every kilowatt-hour you produce. A battery makes this possible by saving your cheap, clean solar energy generated during the day for you to use in the evening.
Projected Savings
Projected Annual Savings with Solar
Your savings depend heavily on whether you can use your solar power on-site or have to sell it back to the grid for a low credit. A battery gives you control over this process.
- With a 6.5 kW solar-only system, a Campbell homeowner might save around $1,970 per year. The estimated payback period is approximately 7.7 years.
- By adding a 10 kWh battery, the modeled annual savings jump to $2,921. The payback period is slightly longer at 8.8 years, but the system delivers nearly $1,000 more in savings each year.
An owned solar system can also be a valuable feature when selling your home, potentially increasing its appeal to buyers looking to avoid high energy costs. Furthermore, it provides a hedge against PG&E's tendency for annual rate increases.
