How to Choose a Solar Installer in Los Angeles

Selecting the right solar company in Los Angelesis one of the most important decisions you'll make when going solar. Here are the key factors to consider before signing a contract:

• Licensing & Insurance

  Confirm the installer holds a valid California contractor license and carries both liability insurance and workers' compensation. Ask for proof before any work begins.

• Customer Reviews & Reputation

  Check reviews on Google, BBB, and SolarReviews. Look for companies serving Los Angeles with 4+ star ratings and a solid track record of completed installations in your area.

• Warranty & Guarantees

  Top solar companies offer 25-year panel warranties, 10-12 year inverter warranties, and workmanship guarantees of at least 10 years. Get all warranty terms in writing.

• Transparent Pricing

  Request detailed, itemized quotes from multiple installers. Beware of companies that won't provide written estimates or use high-pressure sales tactics to rush your decision.

• Local Experience

  Choose a company with experience installing solar systems in Los Angeles and surrounding California communities. Local installers understand regional permitting requirements, utility interconnection rules, and weather conditions.
