How To Choose a Solar Company

Adopting solar power lets homeowners cut 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

It's imperative that your solar installer has the proper licensing. This helps ensure that the work is done properly using current best installation practices. The Maine Electricians' Examining Board issues licenses to professionals installing solar photovoltaic systems in the state. There aren't any special solar licenses; only an electricians' license is necessary.

Read Customer Reviews

Check review sites like Google Reviews, the Better Business Bureau (BBB), and TrustPilot to see customer feedback about local solar companies. Detailed reviews can help you evaluate a company's dependability and level of service. Use caution with providers that have hardly any reviews or mostly negative ones.

Compare Multiple Quotes

Get free, detailed quotes from at least three solar companies. The quotes should outline all costs and identify the exact solar parts included. Looking at several quotes can help you find the option that best fits your budget.

Ask About the Warranty

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

Evaluate Financing and Incentives

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

  • Look into utility rebates: Local power companies may have extra rebates to incentivize homeowners to install solar panels. Review the requirements to qualify and the rebate amounts with your local provider to figure out your potential savings.
  • Research federal and state tax credits: A 26% federal tax credit on total solar system costs is available through 2032. Many states offer incentives, too. The credits can result in substantial savings for solar buyers.
  • Compare system purchase options: Solar panels can be purchased 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.

Cost of Solar Installation in Portland

The cost of home solar panels in Portland will depend on several factors, including the area and generating capacity of your panel array and the type of solar technology being used.
