Are Solar Panels a Smart Investment in McKinleyville in 2026?
For homeowners in the McKinleyville area, high Pacific Gas & Electric Co (PG&E) rates make finding ways to lower electricity bills a priority. Even with the coastal climate's moderate sunshine, a rooftop solar system can offer significant savings. But with the end of the main federal tax credit and new utility rules, does the math still work? The answer often lies in pairing solar panels with a home battery to maximize your energy independence.

Estimated 2026 Solar Installation Costs in McKinleyville
The cost of a solar system depends on your home's energy consumption. For a typical McKinleyville household, here are the estimated upfront costs for an owned system:
- Solar Panels Only (5.0 kW System): The estimated gross cost is approximately $12,750. This system is sized to offset a significant portion of an average local PG&E bill.
- Solar Panels + Battery (5.0 kW System with 10 kWh Battery): The combined estimated cost is $27,750. The battery adds energy storage, which is crucial for maximizing savings under PG&E's current rules and provides valuable backup power.
Incentives & Tax Credits
Key California Solar Benefit for 2026
Although the 30% federal solar tax credit is no longer available for new systems in 2026, California offers a powerful incentive that reduces the long-term cost of ownership:
- Property Tax Exclusion for Solar Systems: When you install solar panels, the value they add to your home is excluded from your property tax assessment. This means you can increase your home's value and utility without increasing your tax bill, a benefit available for systems installed through at least mid-2026.
Your primary return on investment now comes from direct bill reduction, which becomes more valuable every time PG&E raises its rates.

PG&E's Net Billing: Why Self-Consumption Matters
Under PG&E's Net Billing Tariff (NBT), the value of exported solar energy has changed. You'll pay the full retail rate, around $0.323 per kWh, for electricity you pull from the grid. But when your panels produce more energy than you can use and send it to the grid, PG&E credits you at a much lower wholesale rate, modeled here at $0.113 per kWh. This makes it financially smart to store your excess solar power in a battery for use in the evening, rather than selling it to PG&E for a low price.
Projected Savings
Projected Annual Savings with PG&E
The financial benefit of solar is directly tied to how much expensive PG&E power you can avoid buying. Storing your own solar energy is now more valuable than sending it to the grid.
- A solar-only system is projected to save a McKinleyville homeowner around $1,219 per year, leading to a payback period of about 9.3 years.
- By adding a 10 kWh battery, the estimated annual savings increase to $1,739. The battery helps you use more of your own clean energy, offsetting more of your bill. While the payback period is longer at 11.9 years, the system delivers greater total savings and the peace of mind of backup power during grid outages.
An owned solar system can also be a strong selling point for your home, potentially enhancing its resale appeal to future buyers looking for energy savings.
