For homeowners in Redwood City, managing high Pacific Gas & Electric (PG&E) bills is a constant challenge. Rooftop solar remains one of the most effective ways to control energy costs, but the strategy for savings has evolved. In 2026, with no default federal tax credit and low export rates from PG&E, the best financial outcome comes from generating your own power and using as much of it as possible yourself, a strategy known as self-consumption.

How Much Do Solar Panels Cost in Redwood City (2026)?
The estimated cost for a system sized for a typical Redwood City home with a ~$195 monthly bill is detailed below. These 2026 figures do not include a federal tax credit.
- Solar-Only System (5.0 kW): The upfront cost is estimated at $12,750. This system will cover your electricity needs while the sun is shining.
- Solar + Battery System (5.0 kW panels & 10 kWh storage): A combined system is estimated to cost $27,750. This setup provides the best long-term value by storing solar energy for use during expensive evening hours.
An owned solar system can also be an attractive feature for potential buyers, potentially supporting your home's resale appeal in the competitive Bay Area market.
Incentives & Tax Credits
Key California Solar Benefit in 2026
With the federal ITC for homeowners no longer in place by default, California's state-level incentives become even more important. The most significant one is:
- Property Tax Exclusion for Active Solar Systems: When you install solar panels, the value of your home increases, but your property taxes won't. This state law ensures you aren't penalized for making a smart energy investment. This is a considerable benefit in San Mateo County, where property values are high.
The primary driver for going solar remains financial: protecting your household from future PG&E rate hikes and taking control of your energy bills.

Navigating PG&E's Net Billing Tariff
Under the current rules, PG&E credits you at a low wholesale rate for any surplus solar energy you send to the grid. This is much lower than the high retail rate they charge you to buy that same energy back after sunset. This difference is why simply producing a lot of solar energy isn't enough; you have to use it strategically.
A home battery solves this problem. It acts as a personal energy reservoir, storing the excess solar power your panels generate during the afternoon. In the evening, instead of pulling from the grid and paying PG&E's high rates, your home draws from the battery, maximizing the value of your solar investment.
Projected Savings
Projected Annual Savings with Solar in Redwood City
The key to solar savings in 2026 is minimizing how much power you export to PG&E. Power you generate and use at home is worth the full retail rate (around $0.32/kWh), while power you sell to the grid is worth much less (modeled at ~$0.11/kWh).
- A 5.0 kW solar-only system is modeled to save the average household approximately $1,490 per year, leading to a payback period of about 7.8 years.
- By adding a 10 kWh battery, the same system can increase annual savings to $2,165. While the upfront cost is higher, the battery unlocks more significant long-term savings by ensuring you use your own solar power instead of buying expensive evening electricity from PG&E. The estimated payback for the combined system is 10.1 years.
