Wondering how much solar panels cost in Belmont, California, in 2026? With some of the highest electricity rates in the country from PG&E, many homeowners are looking for ways to reduce their monthly bills. The key to a successful solar investment today is designing a system that works intelligently with PG&E's current net billing rules. This often means including a battery to maximize the value of the energy you produce.

Estimated Solar Costs in Belmont (2026)
The cost of a solar installation depends on its size and whether you include battery storage. For a typical Belmont home, here are the modeled estimates for a system designed to offset an average electricity bill. Note that these costs do not include a federal tax credit, which is no longer available for systems installed in 2026.
- 4.5 kW Solar-Only System: The estimated net cost is approximately $11,475.
- 4.5 kW Solar System + 10 kWh Battery: The estimated net cost is approximately $26,475.
Beyond monthly savings, an owned solar system can be a significant asset. It may support your home's resale appeal in the competitive Bay Area real estate market by offering energy savings and predictability to the next owner.
Incentives & Tax Credits
Key California Solar Benefit in 2026
The financial equation for solar has shifted from tax credits to direct energy savings. However, California still provides a crucial incentive for homeowners:
- Property Tax Exclusion for Solar Systems: When you install solar panels, the value they add to your home is excluded from your property tax assessment. This state-level benefit ensures your investment in clean energy won't lead to a higher tax bill.
This exclusion, combined with significant bill savings, forms the foundation of the solar value proposition in Belmont for 2026.

Understanding PG&E's Net Billing Program
With PG&E's current solar program, the electricity you generate and use at home is highly valuable—it directly offsets power you would have bought at retail rates (around $0.32/kWh). However, any surplus energy sent to the grid is credited at a much lower proxy rate (around $0.11/kWh). This makes it financially smarter to store your excess solar energy in a battery for your own use rather than exporting it. A battery helps you keep the full value of your solar production inside your home.
Projected Savings
How Much Can You Save on Your PG&E Bill?
Savings are driven by how much expensive PG&E power you can avoid buying. A battery helps by storing your solar energy for use during peak evening hours when grid power is most expensive.
- A solar-only system is projected to save an average of $1,354 annually, with a payback period of around 7.7 years.
- A solar and battery system increases those savings to an estimated $1,952 annually. The higher upfront cost results in a longer payback of about 10.5 years, but it provides greater long-term bill control and backup power during outages.
If PG&E rates continue to rise, the value of generating and storing your own electricity will only increase over the life of the system.
