Is Rooftop Solar Still a Good Investment in Novato?
With high electricity rates from Pacific Gas & Electric (PG&E) and abundant California sun, many Novato homeowners are evaluating rooftop solar in 2026. The financial equation has changed, as the value of solar now comes primarily from using the energy you generate directly. Understanding how to maximize this self-consumption is crucial for determining if solar is the right fit for your home, especially as average electric bills hover around $178 per month.

Estimated Solar Costs for a Novato Home in 2026
Here’s a look at the modeled upfront investment for a typical solar installation in Novato. These figures do not include a federal tax credit, as the primary credit for homeowners is not available for systems installed in 2026.
- Solar-Only System (4.5 kW): The estimated cost for a system of this size is $11,475.
- Solar + Battery System (4.5 kW solar with 10 kWh battery): Adding a recommended home battery brings the estimated total cost to $26,475. This addition is key for maximizing savings and providing resilience against grid outages.
Incentives & Tax Credits
Key California Solar Benefits in 2026
Even without a federal tax credit, California offers powerful incentives that make solar a practical investment for homeowners.
- Property Tax Exclusion: Your property taxes in Marin County will not increase because you installed a solar system. California law excludes the added value of a qualifying solar installation from your property's assessed value.
- High Rate Offset: The biggest financial driver is avoiding PG&E's high retail rates (around $0.32/kWh). Every bit of solar power you use at home directly offsets electricity you would have otherwise purchased at this high price, creating significant value.

How PG&E's Net Billing Affects Your Solar Savings
Under the current Net Billing Tariff (NBT), PG&E pays homeowners a reduced rate for any surplus solar energy exported to the grid. This analysis models that export compensation at about $0.11 per kWh, which is nearly three times less than the retail rate you pay for electricity. This structure makes it financially advantageous to store your excess solar power in a battery for later use rather than selling it to the grid for a low credit. A battery ensures your valuable solar energy powers your home first.
Projected Savings
Projected Annual Savings on Your PG&E Bill
Your total savings depend on whether you install a battery to store your solar energy. With PG&E's current rules, storing and using your own power is far more valuable than sending it back to the grid for a small credit.
- A 4.5 kW solar-only system is modeled to save approximately $1,354 per year on electricity bills, leading to a payback period of about 7.7 years.
- By adding a 10 kWh battery, the estimated annual savings increase to $1,952. The battery allows you to power your home with stored solar energy during expensive evening hours, significantly reducing what you buy from PG&E. The payback period is longer at around 10.5 years, but the system provides greater long-term value and crucial backup power during outages, a common concern in the region.
An owned solar system is not just about today's bill. It can also enhance your home's resale appeal and provide a hedge against future PG&E rate hikes.
