For homeowners in Windsor, dealing with high and often rising PG&E electricity rates is a familiar challenge. A typical household can face bills around $177 per month. Going solar in 2026 is a practical way to gain control over these costs, but the strategy has shifted. It's no longer just about generating power; it's about using that power intelligently to maximize your savings under California's current net billing rules.

Estimated Solar Costs in Windsor for 2026
With the federal solar tax credit no longer available for systems installed in 2026, the upfront cost is the primary financial consideration. Here are the modeled estimates for a typical home:
- 4.6 kW Solar-Only System: The estimated gross cost is $11,730. This is the more affordable entry point for solar, offering a faster return on investment.
- 4.6 kW Solar System + 10 kWh Battery: This combined package is estimated at $26,730. The higher cost reflects the addition of the battery, which unlocks greater long-term savings and provides backup power.
Incentives & Tax Credits
Key Financial Benefits for Windsor Solar Owners
Even without a federal credit, California provides a crucial incentive that makes going solar more affordable. The property tax exclusion for active solar systems ensures that your home's assessed value—and therefore your property tax bill—will not increase because you installed solar panels.
Furthermore, in a real estate market like Sonoma County, an owned solar and battery system can be a significant asset. It offers potential buyers protection against future PG&E rate hikes, which can enhance your home's resale appeal.

How PG&E's Net Billing Tariff Works
Under PG&E's current rules, known as the Net Billing Tariff (NBT), the value of exported solar energy has changed significantly. The old 1-to-1 net metering credits are no longer available for new solar customers.
Today, the electricity you buy from PG&E costs far more than the credit you receive for sending surplus solar power to the grid. For instance, you might pay over 32¢/kWh for grid power but only receive a credit of around 11¢/kWh for your exports. This structure makes it financially smart to store and use as much of your own solar energy as possible, which is why batteries are now a central part of the conversation.
Projected Savings
Potential Annual Savings with Solar in Windsor
The financial benefit of a solar system is directly tied to how much expensive PG&E power you can avoid buying. With electricity rates over 32 cents per kWh, every bit of self-generated power makes a difference.
- A 4.6 kW solar-only system is modeled to save a typical Windsor home around $1,354 per year. This system has an estimated payback of 7.9 years.
- By adding a 10 kWh battery to that system, the estimated annual savings increase to $1,952. The battery stores solar energy for use after the sun goes down, which is critical for maximizing value.
While the battery extends the payback period to 10.6 years, it provides greater bill reduction and the added security of backup power during grid outages. Long-term utility inflation can also improve the value of this bill offset over time.
