With average electric bills in Milpitas hitting $258 a month, many homeowners are feeling the strain of high PG&E rates, especially during hot summers. Rooftop solar offers a path to energy independence and bill control, but the rules of the game have changed for 2026. The end of the 30% federal tax credit means the financial decision now hinges entirely on maximizing your system's direct value against PG&E's steep prices.
The key to making solar work in today's environment is using the power you generate yourself, rather than selling it back to the grid for a low credit. This is where a home battery becomes a central part of the conversation.

What Do Solar Panels Cost in Milpitas?
The upfront investment is a key factor in any solar decision. With the federal tax credit for homeowners no longer in effect, the gross cost is the final price you pay.
- Solar-Only System (6.6 kW): The estimated gross cost is $16,830.
- Solar + Battery System (6.6 kW solar with 10 kWh battery): The estimated cost for the combined system is $31,830.
These costs are modeled estimates for a complete, professionally installed system. The higher upfront cost of the battery system is offset by greater annual savings and energy resilience.
Incentives & Tax Credits
Key California Solar Benefit in 2026
While federal tax credits for homeowners have expired, California offers a crucial incentive that makes going solar more affordable:
- Property Tax Exclusion for Solar Systems: When you install a solar system, its value is excluded from your property tax assessment. This means you get the benefit of an upgraded home without the burden of a higher tax bill. This exclusion is available for systems installed through at least mid-2026.
Furthermore, an owned solar system can be a powerful feature in the competitive Silicon Valley real estate market. It can add value beyond monthly bill savings by enhancing your home's resale appeal to future buyers looking for energy efficiency and lower living costs.

How PG&E's Net Billing Affects Your Savings
In California, the old 1-for-1 net metering system is gone. Under the current Net Billing Tariff (NBT), there's a major difference between the price you pay for electricity and the credit you get for exporting it.
- Retail Rate: You pay PG&E around $0.32 per kWh for electricity you pull from the grid.
- Export Rate: When your solar panels produce more energy than you can use, the excess is sent to the grid for a credit modeled at just $0.11 per kWh.
This gap is why self-consumption is so important. Using your own solar power saves you from paying the high retail rate. A battery lets you store that valuable energy instead of selling it for pennies on the dollar, allowing you to use it later to avoid peak evening charges.
Projected Savings
Projected 2026 Solar Savings in Milpitas
For a typical Milpitas home, a 6.6 kW solar system can significantly reduce your reliance on PG&E. However, pairing it with a battery unlocks the system's full potential.
- A solar-only system is modeled to save approximately $1,970 in the first year. This is achieved by using solar power as it's generated during the day. The estimated payback period is around 7.8 years.
- By adding a 10 kWh battery, you can store your excess daytime solar energy for use during the evening. This strategy boosts the estimated first-year savings to $2,921. The payback period is extended to 8.9 years, but the long-term savings are much greater, and you gain valuable backup power.
Long-term utility inflation can improve the value of this bill offset over time. As PG&E rates climb, the electricity your panels produce becomes an even more valuable asset.
