How To Choose a Solar Company

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

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. The Maine Electricians' Examining Board issues licenses to professionals installing solar photovoltaic systems in the state. There aren't any special solar licenses; an electricians' license is all that is necessary.

Read Customer Reviews

Check review sites like Google Reviews, TrustPilot, and the Better Business Bureau (BBB) to see customer feedback about local solar companies. Detailed reviews can help you evaluate a company's dependability and customer service. Use caution with companies that have no reviews or mostly negative ones.

Compare Multiple Quotes

To find a solar company that works with your budget, ask for free, detailed quotes from at least three providers. The quotes should list all costs as well as all solar equipment included. Looking at several quotes helps you identify the best value.

Ask About the Warranty

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

Evaluate Financing and Incentives

Going solar can help reduce your energy expenses over time. Be sure to consider these aspects when determining the cost and value of solar panels.

  • Compare system purchase options: Solar panels may be paid for outright or financed over time with leases or loans. Verify key financing details like annual percentage rate (APR), payment schedule, fees, and ownership implications when financing solar panels.
  • Research federal and state tax credits: A 26% federal tax credit on the full cost of solar systems 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 rebates to incentivize homeowners to adopt solar power. Check the requirements and the rebate amounts offered by your local electric provider to determine your potential savings.

Cost of Solar Installation in South Portland

Solar panel costs vary based on your system's capacity and the solar technology used. The typical South Portland solar array has a capacity of 5.2 kilowatts. Homeowners in the area can expect to pay around $3,800 per kilowatt; the average South Portland homeowners spends roughly $13,948 on a new solar system after accounting for federal tax breaks. (Some homeowners prefer to lease solar panels to lower upfront costs.) A personalized quote from a local solar company will account for factors such as the size, capacity, and panel type of the planned system, and should include fees for labor, preliminary work, and permit fees.

With home solar energy, you can recoup the cost of the system over time, lower your home's carbon footprint, and be better prepared if there's an outage to the local grid.

Of course. The grid in South Portland already uses a large share of renewable energy sources, and you may be able to sell your excess generated energy to your utility for additional cost savings.

Your installer can give you an estimate of what your energy bills will look like after you install solar panels. Generally, your energy bills will decrease significantly because you'll be using energy from the sun for free, instead of buying energy from the utility company.
