How To Choose a Solar Company

Going solar can be a great way to save money on electricity costs and help the planet by reducing your carbon footprint using renewable energy. Here are some key factors to consider when evaluating if a solar installer is trustworthy.

Check Licensing

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

Read Customer Reviews

Check TrustPilot, Google Reviews, the Better Business Bureau (BBB), and other review sites to see what past customers have to say about local solar installers. Detailed reviews can help you assess a provider's trustworthiness and customer service. Avoid companies with few or mainly poor reviews.

Compare Multiple Quotes

To find a solar company that fits your budget, ask for free, detailed quotes from 3–5 providers. The quotes should list all costs as well as all solar equipment included. Comparing several quotes helps you identify the most cost-effective option.

Ask About the Warranty

High-quality solar installations should include robust workmanship and performance warranties. The workmanship guarantee covers any installation issues like poor alignment, poor wiring, or cracks in the panels. The output warranty ensures an energy generation baseline. Strong warranties reflect a solar provider's faith in its installations.

Evaluate Financing and Incentives

Installing solar panels can help reduce your electric bills over time. When weighing the total price and value of solar panels, make sure to consider these factors.

  • Research federal and state tax credits: A 26% federal tax credit on total solar system costs is available through 2032. Many states also provide incentives. These credits can result in substantial savings for solar buyers.
  • Look into utility rebates: Some utility companies may provide additional discounts to motivate homeowners to adopt solar power. Check the eligibility criteria and rebate amounts offered by your local electric utility to estimate your potential savings.
  • Compare system purchase options: Solar panels may be paid for outright or financed through leases or loans. Confirm important financing details such as fees, annual percentage rate (APR), payment schedule, and ownership implications when financing your solar system.

West Islip homeowners typically spend about $9,930 on home solar systems after federal tax refunds.

Some homeowners prefer to lease their solar panels in order to reduce upfront costs.
