Analyst Note: Bill-based model (~6.4 kW)

Cost and savings sections below are sized to a typical system for this city’s average utility bill (~6.4 kW modeled). Typical monthly bill here: $258.4.

⚠️ Higher bills usually imply a larger system than the modeled size for full offset—confirm with the calculator below.

For homeowners in Los Gatos, high electricity bills from Pacific Gas & Electric are a constant pressure. With rates around $0.323/kWh, a typical household can easily spend over $250 a month. Rooftop solar offers a path to lower those costs, but the rules have changed. In 2026, the value of going solar depends heavily on using the energy you generate yourself, as selling it back to the grid is less profitable than it used to be. This makes pairing solar panels with a home battery a key strategy for maximizing savings.

Benchmark Cost Analysis

Solar & Battery System Costs in Los Gatos (2026)

The following are modeled estimates for a typical home in the Los Gatos area, based on local pricing and equipment. Since the 30% federal tax credit for solar is no longer available for systems installed in 2026, the gross cost is the net cost.

  • Solar-Only System (6.4 kW): The estimated cost is around $16,320. This system is sized to cover a significant portion of a typical household's electricity usage.
  • Solar + Battery System (6.4 kW panels with 10 kWh battery): Adding a battery increases the total estimated cost to $31,320. The battery stores solar energy for use in the evening, which is critical for savings under current PG&E rules.

An owned solar system can also be a useful long-term home-value feature, potentially enhancing resale appeal for future buyers in the competitive Silicon Valley real estate market.

Incentives & Tax Credits

California Solar Incentives in 2026

While the major federal tax credit has expired for new installations, California homeowners still benefit from important state-level policies that make solar a practical investment.

  • Property Tax Exclusion: Installing a solar system in California will not increase your property taxes. The added value of the solar installation is excluded from your home's valuation for tax purposes, a benefit that runs through at least mid-2026.
  • High Retail Rates: The biggest financial driver for solar in the PG&E service area is the ability to offset some of the highest electricity rates in the country. Every kilowatt-hour you generate and use at home is a kilowatt-hour you don't have to buy from the utility at a premium price.

Understanding Export Rates with PG&E's Net Billing Tariff

Los Gatos homeowners connecting a new solar system to the grid operate under a program called the Net Billing Tariff (NBT). It's different from older net metering programs. Under NBT, the electricity you use at home is worth the full retail rate (over $0.32/kWh), but any excess power you export to the grid is credited at a much lower value based on its wholesale worth. This is why self-consumption is so important. A battery lets you store your excess solar power instead of selling it for a low price, allowing you to use it later when the sun isn't shining and grid power is most expensive.

Projected Savings

How Much Can You Actually Save on Your PG&E Bill?

Savings with solar are no longer just about production; they're about timing. Because electricity sent to the grid is credited at a low rate (modeled here at $0.113/kWh), the biggest savings come from using your own solar power to avoid buying expensive grid power from PG&E.

  • With a solar-only system, the modeled first-year savings are approximately $1,970, leading to a payback period of about 7.6 years.
  • Adding a battery storage system significantly boosts savings by allowing you to use stored solar power at night. This increases the modeled first-year savings to $2,921. While the initial cost is higher, the payback period is still a reasonable 8.8 years, and the system delivers far more bill control.

If grid electricity from PG&E becomes more expensive over time, the value of your rooftop generation increases, potentially shortening your payback period and improving your long-term return on investment.

Local Questions Answered

Is a battery required for solar in Los Gatos?
While not technically required, a battery is highly recommended for maximizing financial returns under PG&E's Net Billing Tariff. Without a battery, you export surplus daytime energy for a low credit and must buy expensive energy from the grid at night. A battery lets you store that surplus and use it yourself, dramatically increasing your savings.
What happens if the power goes out?
A standard solar-only system will shut down during a grid outage for safety reasons. To have backup power during an outage, you need a battery storage system. This provides an additional layer of energy security, which is a valuable benefit for many homeowners.
With no federal tax credit, is solar still a good investment?
Yes, for many homeowners. The payback period is now slightly longer, but the long-term savings from offsetting high and rising PG&E rates are substantial. The key is to size the system correctly and, ideally, include a battery to maximize self-consumption. Use the calculator below to see numbers for your specific home.
