Facing high PG&E bills, especially during hot summers near Folsom Lake, many Granite Bay homeowners are considering solar power. In 2026, the smartest way to go solar involves pairing panels with a battery. This combination directly tackles high electricity costs by allowing you to store and use your own solar energy, which is now far more valuable than selling it back to the grid for a low credit. An owned system is also a great long-term feature that can improve your home's resale appeal.

Estimated Solar System Costs in Granite Bay (2026)
The upfront investment in solar depends on the system size and components. For a typical Granite Bay home, a 6.7 kW system is a common size to offset a significant portion of the electricity bill. Here’s a look at the estimated costs:
- 6.7 kW Solar-Only System: The estimated gross cost is $17,085.
- 6.7 kW Solar System + 10 kWh Battery: The estimated combined cost is $32,085.
While adding a battery increases the initial price, it unlocks much greater long-term savings under PG&E's current rules, making it a recommended choice for maximizing your return on investment.
Incentives & Tax Credits
Key California Solar Benefits in 2026
The era of large federal tax credits for residential solar has passed. For systems installed in 2026, the financial benefits come from state-level policies and the sheer value of offsetting high utility rates.
- Property Tax Exclusion: In California, adding a solar system to your home will not increase your property taxes. This valuable exclusion is available for systems installed through June 30, 2026.
- No State or Federal Tax Credits: Homeowners should not expect a state income tax credit or the expired 30% federal ITC. The savings are now built directly into the energy production and bill reduction.
The primary incentive is producing your own power for a fraction of what PG&E charges, giving you more predictable energy costs for years to come.

How PG&E's Net Billing Tariff Works
Granite Bay is in PG&E territory, which operates under a Net Billing Tariff (NBT). This structure is critical to understand:
- When you use the solar power you generate inside your home, you are avoiding PG&E's retail rate of over $0.32 per kWh. This is high-value energy.
- When you export surplus solar power to the grid, PG&E only credits you at a much lower rate, modeled here at around $0.11 per kWh.
This export rate is why simply sending power back is no longer the best option. A battery allows you to keep your valuable solar energy for yourself, dramatically improving the economics of your system.
Projected Savings
Maximizing Your Savings with Solar and Storage
In Granite Bay, the financial benefit of solar is all about self-consumption—using the power you generate to avoid buying expensive electricity from PG&E. The hot inland summers mean heavy air conditioner use, making this strategy particularly effective.
- A solar and battery system is modeled to deliver approximately $2,921 in electricity bill savings per year, with a payback period of around 8.9 years.
- Without a battery, a solar-only system would save closer to $1,970 per year, and its payback is estimated at 7.9 years.
The nearly $1,000 difference in annual savings comes from the battery. It stores the abundant solar energy your panels produce during the day, so you can power your home and A/C in the late afternoon and evening when electricity from the grid is most expensive. This protects you from future PG&E rate hikes, which can improve the value of your investment over time.
