Payback lengthens with size here: exported power is credited at an avoided-cost rate well below retail, so oversizing has a smaller payoff than under true net metering.
What makes Sacramento different
1. SMUD is a municipal utility
Sacramento is served by SMUD, a publicly owned utility rather than an investor-owned one. You cannot shop retail electricity providers the way most of the state can. Your rate, credit program and interconnection process all come from SMUD.
2. Export credit is set by the utility, not the market
SMUD credits exported power at a rate it sets itself. In practice you are paid less for what you export than you pay for what you import, so sizing to your own usage matters more here than under true net metering.
3. Exported power is credited at avoided cost
Sacramento sits in an avoided-cost regime: exports are valued below retail, often well below. Batteries that let you self-consume instead of export carry more value here than in a true net-metering market.
4. High local rates shorten payback
At about 32¢/kWh, Sacramento has rates well above the national average. High rates are the single biggest reason payback is faster here than in most of the country — and the reason self-consumption, not export, drives the return.
What affects your price in Sacramento
- System size — the single biggest driver.
- Roof pitch and height — steep or two-storey roofs add labour.
- Roof age — replace worn shingles first; re-roofing around panels costs more later.
- Panel and inverter tier — premium modules and microinverters add 15–25%.
- Main panel upgrade — older homes may need a 200A service upgrade, $1,500–$3,000.
- Battery — optional, roughly $10,000–$15,000 installed.
- Season — late autumn and winter installs are often cheaper.

Sacramento solar FAQ
How much do solar panels cost in Sacramento?
A 6 kW system — the most common size locally — costs about $18,000 installed before incentives, or $12,600 after the 30% federal tax credit and local rebates.
How long is the payback period in Sacramento?
Roughly 3.6 years for a properly sized system, based on local rates, 1800 kWh of production per installed kW, and current incentives.
Does SMUD offer a rebate?
Programs and funding change. Confirm the current SMUD incentive directly with the utility, and never accept an installer's rebate promise that isn't in writing.
Do I need a permit to install solar in Sacramento?
Yes. Sacramento requires an electrical and structural permit plus an inspection, and SMUD handles interconnection separately. A reputable installer files all of it — ask to see the permit number.
How much roof space does a system need?
A 6 kW array needs roughly 390–510 square feet of unshaded roof, depending on panel wattage and layout.
Is Sacramento a good place for solar?
The sun resource is strong at about 1800 kWh per installed kW per year, and local rates run near 32¢/kWh. The real variables are roof condition, shading and SMUD's export credit rules.
