Is Rooftop Solar Still a Good Investment in Woodbridge?
With Pacific Gas & Electric (PG&E) rates at $0.368/kWh, many homeowners are looking for ways to reduce their monthly electricity bills, especially during hot San Joaquin Valley summers. In 2026, the financial equation for solar has changed. While the default federal tax credit for homeowners is no longer available, high grid electricity costs mean that generating and using your own power is more valuable than ever. The key is maximizing how much solar energy you use directly in your home.

2026 Solar & Battery System Costs in Woodbridge
The cost of a solar installation depends on whether you include a home battery. A battery allows you to store the solar energy you produce during the day and use it during the evening, which is critical under current PG&E rules for maximizing savings.
- Solar-Only System (6.3 kW): The estimated gross cost is around $16,065. This system is sized to cover a significant portion of a typical home's electricity usage.
- Solar + Battery System (6.3 kW solar with 10 kWh battery): The estimated gross cost is $31,065. This configuration provides greater energy independence and higher bill savings by reducing reliance on the grid, especially during peak-rate hours.
Incentives & Tax Credits
California Solar Incentives Beyond Tax Credits
As of 2026, the 30% federal residential clean energy credit is no longer available for systems placed in service this year. However, California homeowners still benefit from important state-level policies that support the value of solar energy.
- Property Tax Exclusion: The most significant financial perk is California's property tax exclusion for active solar energy systems. Installing solar panels will not increase your property taxes, ensuring the value added to your home doesn't result in a higher tax bill.
- High Energy Rates: While not a direct incentive, California's high retail electricity rates are a powerful driver for solar adoption. The higher the price of grid power, the more valuable each kilowatt-hour of self-generated solar becomes.

Understanding Export Rates vs. Retail Rates (Net Billing)
Under California's net billing system, the electricity you buy from PG&E is much more expensive than the credit you receive for exporting surplus solar power. You pay the full retail rate of $0.368/kWh but only get credited around $0.12/kWh for the energy you send back. This difference is why home batteries are now strongly recommended. By storing your excess solar power in a battery, you can use it later instead of selling it to the grid for a low price and buying it back for a high price. It puts you in control of your energy and your savings.
Projected Savings
How Solar Translates to Bill Savings with PG&E
Your savings depend on how much of the solar power you use yourself versus how much you send back to the grid. With PG&E's high retail rate of $0.368/kWh, every kilowatt-hour of solar you use at home is a direct saving of that amount.
- A 6.3 kW solar-only system in Woodbridge is modeled to produce annual savings of approximately $2,156, leading to a payback period of about 6.9 years.
- Adding a 10 kWh battery significantly increases those savings. The same 6.3 kW system paired with storage is projected to save $3,308 annually. While the initial cost is higher, the payback period is only slightly longer at 7.9 years, and your savings are nearly 50% greater each year.
If grid electricity becomes more expensive over time, rooftop generation can offset costlier power in future years, making the investment even more valuable.
