How To Choose a Solar Company

Adopting solar power lets homeowners reduce utility bills while benefiting the planet by reducing your carbon footprint using clean energy. If you’re deciding whether to go solar, consider these key factors for choosing an installer.

Check Licensing

Hiring a licensed solar installer is critical. This ensures that the work is done correctly using the most up-to-date installation methods. New York state does not issue licenses to contractors, so you should check with your county or city government for its specific requirements and regulations.

Read Customer Reviews

Look at review platforms such as Google Reviews, TrustPilot, and the Better Business Bureau (BBB) to find out what previous customers have to say about local solar providers. Reviews can give you an idea of a company’s reliability and customer service. Be wary of companies lacking reviews or with predominantly negative feedback.

Compare Multiple Quotes

Call 3–5 solar companies for free, itemized quotes. These quotes should outline all costs and list the solar equipment included. Reviewing multiple quotes helps identify the option that aligns with your budget.

Ask About the Warranty

Top-notch solar installations should come with strong workmanship and performance warranties. A workmanship guarantee covers installation defects, such as poor alignment, cracks in the panels, or poor wiring. A performance guarantee ensures a minimum energy output. Comprehensive warranties indicate that a solar company believes in its work.

Evaluate Financing and Incentives

Solar panels can help lower your electricity costs over time. When weighing solar panel's cost and value, be sure to consider these considerations.

  • Compare system purchase options: Solar panels may be paid for outright or financed over time with a lease or loan. Verify key financing details like payment schedule, annual percentage rate (APR), fees, and ownership implications when choosing to finance solar panels.
  • Research federal and state tax credits: There’s a 26% federal tax credit available for total solar system costs until 2032. Many states also offer incentives. The credits can add up to significant savings for solar buyers.
  • Look into utility rebates: Some utility companies may provide additional rebates to encourage homeowners to adopt solar power. Check the requirements and the rebate amounts offered by your local power company to determine the possible savings.
