With some of the highest electricity rates in the country from San Diego Gas & Electric, many Santee homeowners are looking for ways to reduce their monthly bills. In 2026, the solar landscape has changed. The default federal tax credit for homeowners is no longer available, and SDG&E's export compensation rates are lower than retail prices. This shifts the focus to maximizing the power you produce and use at home, making solar-plus-battery systems a powerful strategy for bill reduction.

How Much Do Solar Panels Cost in Santee in 2026?
For a typical Santee home, a 7.0 kW solar system costs approximately $17,850 before any incentives. This system is sized to offset a significant portion of the average local electricity bill.
Pairing that system with a 10 kWh battery for energy storage brings the total estimated cost to $32,850. The battery allows you to store solar energy generated during the day and use it during the evening, which is critical for maximizing savings under current utility rules.
Incentives & Tax Credits
California Solar Incentives for 2026
While the 30% federal tax credit for residential solar installations is no longer the default, California homeowners still have access to meaningful financial benefits:
- Property Tax Exclusion: Your property taxes will not increase due to the value added by your solar system. This state-level exclusion is a significant benefit that saves you money every year.
- High Self-Consumption Value: With SDG&E's high retail electricity rates (around $0.323/kWh), every kilowatt-hour of solar energy you use at home provides substantial savings. This makes self-consumption far more valuable than exporting power to the grid.
- Increased Home Value: An owned solar system can be an attractive feature for potential buyers, potentially supporting your home's resale appeal in the competitive San Diego County market.

Understanding SDG&E's Net Billing Rules
Santee operates under a net billing tariff, which is different from older net metering programs. Here’s what that means for you: the electricity you buy from SDG&E is expensive, but the excess solar energy you export back to the grid is credited at a much lower rate (modeled here at around $0.113/kWh).
This structure makes it financially smart to use as much of your own solar power as possible. A battery is the key to achieving this. It stores your excess daytime solar power so you can use it in the evening, instead of selling it to the grid for a low credit and then buying expensive power back just a few hours later.
Projected Savings
Projected Electricity Bill Savings
Installing a 7.0 kW solar-only system in Santee could save you an estimated $2,216 annually on your SDG&E bills, leading to a payback period of about 7.4 years. If utility rates continue to climb, the value of these savings can grow over the system's lifespan.
Adding a battery significantly increases your ability to use the power you generate. A solar-plus-battery system is projected to save $3,308 per year. While the initial investment is higher, the increased savings and added benefit of backup power during outages make it a compelling option for many. The payback period for the combined system is estimated at 8.2 years.
