Paying over $200 a month to SMUD has become the norm in the Sierra foothills, but a major policy shift called Net Billing (NEM 3.0) changed how solar works. Homeowners now face a critical choice: install solar panels alone and get pennies on the dollar for exported power, or pair them with a battery to achieve true energy independence and maximize savings. For virtually everyone in El Dorado Hills, the second option is the only one that makes financial sense in 2026.
Benchmark Cost Analysis
What Do Solar and Battery Systems Cost in El Dorado Hills?
Expect a typical solar and battery installation to have a gross cost around $23,500. While a solar-only system seems tempting at just $11,500, it's a poor long-term investment under Net Billing. The key is focusing on the post-incentive cost. After the 30% federal tax credit, the net cost for the recommended solar and battery system drops to just $16,450. This investment achieves a payback period of about 10 years, after which you're generating nearly free power for the life of the system.
Incentives & Tax Credits
Federal & State Solar Incentives Available
The most significant incentive is the federal Residential Clean Energy Credit, which allows you to deduct 30% of the total system cost (panels and battery) from your federal taxes. That's a $7,050 credit on a $23,500 system. Additionally, California's property tax exclusion means your home's assessed value won't increase because you added a solar system, preventing higher property tax bills.

Understanding SMUD's Net Billing Rules in 2026
Under the old net metering rules, SMUD credited you at a near-retail rate for any excess solar power you sent back to the grid. Under the new Net Billing tariff, that's over. Now, the export credit is slashed to just 5-8 cents per kWh during many hours. Sending your valuable solar energy to the grid is a financial loser. A battery solves this problem entirely. Instead of exporting for pennies, you store your excess solar energy generated during the day and use it to power your home during the evening when SMUD's rates are highest. This strategy, called self-consumption, is the key to significant savings.
Projected Savings
How a Solar + Battery System Delivers Real Savings
By storing your solar power, you can offset almost your entire electricity bill. A typical 4 kW solar array paired with a 10 kWh battery in El Dorado Hills generates around $1,614 in annual savings. This protects your family from SMUD's constant rate increases and provides priceless peace of mind during fire season Public Safety Power Shutoffs (PSPS). A solar-only system, by contrast, would only save around $1,145 annually, with those savings shrinking each time SMUD adjusts its export rates downward.
