Thinking about going solar in Glendora in 2026? A key question for homeowners is the total cost and whether the investment still pays off without the federal tax credit. The answer depends on the system you choose, particularly whether you include a battery. With high electricity rates from Southern California Edison, generating your own power is more valuable than ever, but maximizing that value requires the right setup.

Estimated Solar System Costs in Glendora (2026)
For a typical home in the Glendora area, here are the modeled costs for a solar installation. These figures reflect pricing after the expiration of the federal residential tax credit.
- 7.2 kW Solar-Only System: The estimated upfront cost is $18,360. This system is designed to cover a large portion of an average household's electricity needs during daylight hours.
- 7.2 kW Solar System + 10 kWh Battery: The estimated total cost is $33,360. This integrated system is recommended to achieve the highest possible savings and provides the added benefit of backup power.
These estimates are based on an average cost of $2.55 per watt and are intended to provide a clear baseline before you seek personalized quotes.
Incentives & Tax Credits
Key California Solar Incentive: Property Tax Exclusion
In 2026, the primary state-level incentive for homeowners in Glendora is California's property tax exclusion for active solar energy systems. When you install solar panels, the value of your home increases, but this law ensures your property tax bill does not go up as a result. This is a significant, long-term financial benefit that directly improves your return on investment.
Furthermore, an owned solar system is an attractive asset that can enhance your home's resale appeal. It offers prospective buyers the promise of lower, more predictable energy bills, a valuable feature in Southern California's expensive energy market.

Why Self-Consumption is Crucial with SCE's Net Billing
California's energy policy, known as net billing, has changed how solar owners are compensated for excess energy. When your panels produce more power than you're using, that power flows to the grid. Southern California Edison will credit you for it, but at a wholesale-based rate—modeled here at about $0.11 per kWh.
This is much lower than the retail rate you pay for electricity, which is around $0.32 per kWh. Because of this gap, it's far more economical to store your excess solar energy in a battery and use it yourself later. This strategy, called self-consumption, ensures you get the full retail value from every kilowatt-hour your panels produce, which is why a battery is now a central part of a financially optimized solar system.
Projected Savings
Projected Annual Savings: Solar vs. Solar + Battery
The savings you achieve are directly tied to how much expensive grid power you can avoid buying from SCE. This is where a battery makes a significant difference.
- With a solar-only system, you can expect to save around $2,216 per year on your electricity bills, leading to a payback period of approximately 7.6 years.
- By adding a battery, your modeled annual savings increase substantially to $3,308. The battery allows you to store solar energy generated during the day and use it during the evening peak hours, when grid electricity is most expensive. While the initial investment is higher and the payback period is slightly longer at 8.3 years, the total long-term savings are much greater.
Solar is not only about today's bill. As utility rates continue to climb, the value of each kilowatt-hour your system produces increases, making it a powerful hedge against energy inflation.
