For homeowners in Eureka, the high cost of electricity from Pacific Gas & Electric (PG&E) makes finding ways to save money a priority. Rooftop solar is a powerful tool for reducing that monthly bill, but PG&E's current rules have changed how homeowners get the most value from their systems. In 2026, with no federal tax credit available, success with solar hinges on using the power you generate yourself rather than exporting it to the grid. This shift makes battery storage a central part of the conversation.

Estimated Solar Panel Costs in Eureka (2026)
For an average home in the Eureka area, a 5.7 kW solar panel system is a common size to offset a significant portion of the household's electricity usage. The estimated upfront cost for this system in 2026 is $14,535.
To maximize your savings under PG&E's rules, pairing your panels with a home battery is recommended. A 5.7 kW system combined with a 10 kWh battery is estimated to cost $29,535. While the initial investment is higher, this setup allows you to store your own solar energy for use at night, providing greater long-term value and energy independence.
Incentives & Tax Credits
California's Solar Property Tax Benefit
Even without a federal incentive, California provides a crucial financial benefit for solar owners. The state's Property Tax Exclusion means that your property taxes will not increase because of the added value of your solar system. This is a significant, long-term advantage that makes the investment more attractive. Additionally, an owned solar system is a modern feature that can improve your home's resale appeal, as it offers the next owner a path to lower energy bills.

How PG&E's Net Billing Affects Solar Savings
Under PG&E's current program, known as Net Billing Tariff (NBT), the value of solar energy you export to the grid is much lower than the price of energy you buy from it. The compensation for exported electricity is based on "avoided cost" rates, which can be as low as a few cents per kWh depending on the time of day. Our model uses an estimate of $0.113 per kWh for exported power.
Because you buy power for $0.323 per kWh but only get credited around $0.113 per kWh for what you sell, it's far more economical to store and use your own solar energy. This is the fundamental reason why a solar-plus-battery system is now the recommended path for most PG&E customers.
Projected Savings
Projected Savings with Solar in Eureka
The financial benefit of going solar in Eureka comes directly from avoiding PG&E's high retail rate of around $0.323 per kWh. A 5.7 kW solar-only system is modeled to save a homeowner approximately $1,354 in the first year, with a payback period of about 9.6 years.
However, adding a battery to the system increases the first-year savings to $1,952. Why the big jump? A battery lets you store the solar power your panels generate during the day and use it in the evening. This prevents you from having to buy expensive electricity from PG&E after the sun sets and is the key to maximizing your system's value. Solar also provides a hedge against future utility rate hikes; if grid power becomes more expensive, the value of your self-generated electricity increases.
