High electricity bills from Southern California Edison are a familiar challenge in Glen Avon, especially with heavy air conditioning use in the summer. While rooftop solar is a powerful way to lower those costs, the rules have changed. In 2026, simply sending your excess solar power to the grid isn't the best financial strategy. The value of that exported power is significantly lower than the price you pay for electricity, which changes the math on how to get the most from your investment.

2026 Solar & Battery System Costs in Glen Avon
The total cost for a residential solar installation depends heavily on whether you include a home battery. Here are the modeled estimates for a typical home in the area:
- Solar-Only System (7.0 kW): The estimated gross cost is $17,850. This system is sized to offset a significant portion of a typical household's electricity usage.
- Solar + Battery System (7.0 kW panels with 10 kWh battery): The estimated gross cost is $32,850. This configuration is recommended to maximize your energy independence and savings under current utility rules.
These figures are based on a modeled cost of $2.55 per watt before any local incentives. Since the federal tax credit for homeowners is no longer available for systems installed in 2026, these gross costs represent the full investment.
Incentives & Tax Credits
California Solar Incentives for 2026
While the 30% federal ITC for homeowners has expired, California still offers meaningful financial benefits that make going solar a smart long-term investment for your home.
The most significant incentive is the Active Solar Energy System Property Tax Exclusion. This state rule prevents your property taxes from increasing due to the added value of your solar system. For systems installed through mid-2026, this is a major benefit that can save you thousands over the life of the system.
Additionally, an owned solar system can be a compelling feature for potential buyers, potentially supporting your home's resale appeal. It signals lower, more predictable energy costs, which is a strong selling point in a state with high utility rates.

Understanding Export Rates with Southern California Edison (SCE)
Under California's current net billing structure, the financial benefits of solar have shifted from exporting power to using it yourself. When your panels produce more electricity than your home is using, the excess is sent to the grid. However, SCE credits you for that power at a rate much lower than what they charge you to buy it.
This model estimates your export credit at around $0.11 per kWh, while you pay SCE roughly $0.32 per kWh to pull power from the grid. This difference is why a battery is so highly recommended. By storing your excess solar power, you can use it later instead of exporting it for a low credit and then buying expensive power back in the evening. This strategy, known as self-consumption, is the key to maximizing solar savings in 2026.
Projected Savings
How a Battery Maximizes Your Solar Savings
Adding a battery changes how you use your solar energy, leading to greater bill reductions. With SCE's high retail rate of around $0.32 per kWh and a much lower export credit, using your own solar power is far more valuable than selling it.
- A solar-only system is modeled to save approximately $2,216 annually, with a payback period of about 7.4 years. It works by offsetting usage during the day.
- A solar-plus-battery system boosts annual savings to an estimated $3,308. The battery stores your excess solar energy from the daytime to power your home in the evening, avoiding the need to buy expensive grid power after the sun sets. While the payback period extends slightly to 8.2 years, the long-term financial return is stronger, and you gain valuable backup power during outages.
If grid electricity becomes more expensive over time, the power generated and stored by your system will become even more valuable, improving your return on investment in future years.
