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 evaluating if you want to go solar, consider these key factors for choosing an installer.

Check Licensing

Make sure you hire a licensed solar installer. This ensures that the work is done properly using the most up-to-date installation methods. Licensing requirements mean that your New Jersey solar installation team will likely have a variety of different professionals, including . The master-level professionals on the team will also handle permit work for the job.

Read Customer Reviews

Check review sites like Google Reviews, the Better Business Bureau (BBB), and TrustPilot to see feedback from past customers about local solar companies. Detailed reviews can help you assess a company's reliability and customer service. Use caution with providers that have very few reviews or mostly negative ones.

Compare Multiple Quotes

Get free, detailed quotes from at least three solar companies. A quote should outline all costs and identify the exact solar parts included. Comparing several quotes can help you find the most cost-effective option.

Ask About the Warranty

Top-notch solar installations should come with strong workmanship and performance warranties. A workmanship warranty covers installation issues, such as cracks in the panels, poor alignment, 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 energy can help reduce your electricity costs over time. When considering solar panel's cost and value, be sure to consider these considerations.

  • Look into utility rebates: Local utility companies may offer additional rebates to encourage homeowners to adopt solar panels. Check the requirements to qualify and the rebate values with your local utility provider to determine what your savings could be.
  • Research federal and state tax credits: A 26% federal tax credit on total solar system costs is available through 2032. Many states provide incentives, too. The credits can result in substantial savings for solar buyers.
  • Compare system purchase options: Homeowners may purchase solar panels outright or spread out payments over time with loans or leases. Be sure to confirm key details like fees, annual percentage rate (APR), payment schedule, and what ownership means when financing solar panels.

Cost of Solar Installation in Williamstown

Solar panel costs vary based on system capacity and the solar technology used. The typical Williamstown solar array has a capacity of 4.6 kilowatts. Homeowners in the area can expect to pay approximately $3,530 per kilowatt; the average Williamstown homeowners spends roughly $11,485 on a new solar array after accounting for federal tax breaks. (Some homeowners prefer to lease solar panels to reduce upfront costs.) A personalized quote from a local solar provider will account for factors such as the capacity, size, and panel type of the planned system, and should include prices for labor, preliminary work, and permit fees.
