How To Choose a Solar Company

Putting solar panels on your roof could cut your electricity payments while helping the environment by reducing your carbon footprint through renewable energy use. Key considerations when researching local solar installers are as follows.

Check Licensing

It's important to hire a licensed solar installer. This help guarantee 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 city or county government for its specific requirements and regulations.

Read Customer Reviews

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

Compare Multiple Quotes

Contact 3–5 solar companies for free, detailed quotes. Quotes should clearly explain all costs and list the exact solar components included. Comparing multiple quotes helps identify the option that best fits your budget.

Ask About the Warranty

Quality solar installations should come with strong workmanship and performance guarantees. A workmanship guarantee addresses any installation defects (such as cracks in the panels, poor wiring, or poor alignment), while a performance warranty ensures a certain level of energy production. Strong guarantees demonstrate a company's confidence in its work.

Evaluate Financing and Incentives

Solar energy is great for helping you lower electricity bills over time. Be sure to consider these aspects when considering the final cost and value of solar panels.

  • Compare system purchase options: Homeowners may purchase solar panels outright or finance payments over time with a lease or loan. Be sure to confirm key details like fees, payment schedule, annual percentage rate (APR), and what ownership means when financing 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: Local power companies may have extra financial benefits to encourage homeowners to install solar panels. Review the requirements to qualify and the rebate amounts with your local provider to figure out your potential savings.

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