With high electricity bills and plenty of sun in the Sierra foothills, many Oroville homeowners are asking if solar is still a good investment in 2026. The answer is yes, but the strategy has changed. The 30% federal tax credit is gone, and Pacific Gas & Electric's (PG&E) rules now reward homeowners who use their own solar power instead of just exporting it. This shift makes pairing solar panels with a home battery a more effective way to lower your energy costs and gain independence from the grid.

2026 Solar Installation Costs in Oroville
The following estimates are for a 6.3 kW solar system, sized for a typical Oroville home's electricity needs. These costs reflect pricing after the expiration of the federal residential solar tax credit.
- Solar-Only System Estimated Cost: $16,065. This setup is the most affordable entry point and works well to reduce your energy consumption during sunny hours.
- Solar + 10 kWh Battery System Estimated Cost: $31,065. Adding a battery increases the initial investment but unlocks greater long-term savings by storing solar energy for use at night, which is crucial under PG&E's current rate structure.
Incentives & Tax Credits
Key California Solar Incentives for 2026
Even without a federal tax credit, California offers valuable incentives that support the move to solar.
- Property Tax Exclusion for Solar Systems: This is the most significant financial perk. The entire value of your solar installation is exempt from property taxes in California. You can improve your home without paying more in taxes.
- Utility Net Billing: While not a direct cash incentive, PG&E's net billing program provides bill credits for any surplus energy you export to the grid. However, since these credits are below the retail rate, the program incentivizes self-consumption and battery storage.

How PG&E's Net Billing Affects Solar Savings
In the past, net metering offered a simple 1-for-1 credit swap. Today's Net Billing Tariff (NBT) is different. When your solar panels produce excess power, you sell it to PG&E for a fraction of what it costs to buy power back later. For instance, you might get an export credit of $0.11 per kWh, but pay $0.32 per kWh to run your appliances after the sun goes down.
This structure makes a strong case for a battery. A battery acts as a personal energy reservoir, letting you store your low-cost solar energy instead of selling it cheap. You then use that stored energy at night, directly avoiding PG&E's expensive rates and keeping the full value of your solar production for yourself.
Projected Savings
Projected Energy Savings with Solar in Oroville
Generating your own power is a direct way to combat high PG&E rates, which average around $0.32 per kWh. The financial return depends on how much of that solar energy you can use on-site.
- A solar-only system is projected to save an Oroville household approximately $1,773 per year, with an estimated payback period of 8.2 years.
- By adding a battery, you can use stored solar power in the evening instead of buying from the grid. This boosts the estimated annual savings to $2,611. The payback period extends to about 9.5 years, but the system provides more significant bill reduction and resilience against outages.
An owned solar and battery system is also a modern feature that can enhance resale appeal, showing potential buyers a path to lower, more predictable energy bills.
