What makes Los Angeles different
1. LADWP is a municipal utility
Los Angeles is served by LADWP, 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 LADWP.
2. Export credit is set by the utility, not the market
LADWP 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. Net metering, but mid-transition
Exports are still credited close to retail in Los Angeles, but the policy is being phased down in many markets. Grandfathering rules and application dates matter — check the current schedule before signing.
4. High local rates shorten payback
At about 32¢/kWh, Los Angeles 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 Los Angeles
- 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.

Los Angeles solar FAQ
How much do solar panels cost in Los Angeles?
A 6 kW system — the most common size locally — costs about $18,300 installed before incentives, or $12,810 after the 30% federal tax credit and local rebates.
How long is the payback period in Los Angeles?
Roughly 3.8 years for a properly sized system, based on local rates, 1750 kWh of production per installed kW, and current incentives.
Does LADWP offer a rebate?
Programs and funding change. Confirm the current LADWP 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 Los Angeles?
Yes. Los Angeles requires an electrical and structural permit plus an inspection, and LADWP handles interconnection separately. A reputable installer files all of it — ask to see the permit number.

A 6 kW array needs roughly 390–510 square feet of unshaded roof, depending on panel wattage and layout.
Is Los Angeles a good place for solar?
The sun resource is strong at about 1750 kWh per installed kW per year, and local rates run near 32¢/kWh. The real variables are roof condition, shading and LADWP's export credit rules.
