Going solar in Orange County looks different in 2026. Southern California Edison customers on the state's net billing rules earn less for power sent back to the grid, so many systems now include a battery. The federal tax credit for systems homeowners buy ended after 2025, which has pushed more installers to offer leases and prepaid power agreements. Homeowners now weigh crews, battery certifications, warranty length and financing as closely as panel brand.
This guide compares seven solar companies with offices in Orange County. Infinity Solar ranks first for homeowners who want a long-running local installer with its own crews and certified battery installs. The others range from a high-volume Irvine installer to a commercial contractor.

Why they lead the list: Infinity Solar has held a California C-10 electrical license since 2003, which matters now that most Orange County projects include a battery, a panel upgrade or an EV charger. Its own crews handle installation instead of subcontractors, and the company sells directly rather than through brokers. It also publishes typical price ranges for 5, 7 and 10 kW systems, so homeowners can check a quote against a range before signing.

Primary factors
Secondary factors
Orange County homeowners have plenty of solar installers to choose from, and the right one depends on the project. Infinity Solar ranks first because it pairs a long-held electrical license with its own installation crews, battery certifications and published price ranges.
Before signing, get at least three quotes, compare the price per watt and the workmanship warranty in writing, ask who will do the installation, and confirm how a battery will work under Edison's current billing rules.
