Estimated 2026 Solar System Costs in Alum Rock
For a home with an average electric bill of around $233, a 5.8 kW solar system is a common size. Here’s a look at the modeled upfront costs in early 2026, keeping in mind the 30% federal ITC is no longer available for new systems.
- 5.8 kW Solar-Only System: The estimated gross cost is $14,790.
- 5.8 kW Solar System + 10 kWh Battery: Adding home energy storage brings the estimated total to $29,790.
While the solar-plus-battery option has a higher initial investment, it's designed to deliver greater savings over time under PG&E's current rate structure.
Incentives & Tax Credits
Key Financial Benefits for Solar in California
In 2026, the financial case for solar relies on direct bill savings and state-level perks rather than federal credits. The most important incentive available to Alum Rock homeowners is:
- California Property Tax Exclusion: Your property taxes will not increase as a result of installing a solar energy system. This state-level exclusion prevents your home's assessed value from rising due to the added value of the panels, saving you money every year.
The primary incentive remains avoiding PG&E's high retail electricity rates, which average over $0.32/kWh. Every kilowatt-hour of solar energy you use at home is a kilowatt-hour you don't have to buy from the utility.

How PG&E's Net Billing Program Works
For new solar customers, PG&E operates under a net billing tariff. It's a simple concept: the energy you use from the grid during evenings or cloudy days is expensive. The surplus solar energy your system sends to the grid is purchased by PG&E for a much lower price. This structure is specifically designed to encourage self-consumption. A solar and battery system allows you to store your valuable solar energy and use it yourself, dramatically reducing what you export for low credit and what you must buy from the grid at high prices.
Projected Savings
Projected Annual Savings: Solar vs. Solar + Battery
The financial return from solar in Alum Rock depends heavily on how much of the energy you generate is used on-site. Any excess sent to the grid is credited at a low rate, which is why batteries have become so popular.
- With a solar-only system, you could expect to save around $1,773 per year on your PG&E bills. The system pays for itself in an estimated 7.6 years.
- By adding a battery, you store excess solar power generated during the day and use it at night. This boosts your annual savings to an estimated $2,611. The payback period is longer at 9.2 years, but the system generates nearly 50% more savings each year.
An owned solar system is also a long-term asset. It can protect you from future PG&E rate hikes and may improve your home's resale appeal to future buyers who also want energy independence.
