How To Choose a Solar Company

Adopting solar power lets homeowners lower utility bills while helping the environment by reducing your carbon footprint using clean energy. If you’re determining whether to go solar, consider these key factors for choosing an installer.

Check Licensing

It's important to hire a licensed solar installer. This helps ensure that the work is done properly using current installation best practices. Massachusetts requires new solar PV systems in the Commonwealth to be installed by a licensed electrician and new solar water heaters to be installed by a construction supervisor.

Read Customer Reviews

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

Compare Multiple Quotes

Contact 3–5 solar companies to get free, detailed quotes. Quotes should clearly explain all costs and list the exact solar components included. By comparing multiple quotes, you can identify the most cost-effective option for you.

Ask About the Warranty

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

Evaluate Financing and Incentives

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

  • Look into utility rebates: Some energy providers may provide additional rebates to motivate homeowners to adopt solar power. Check the qualification rules and rebate amounts offered by your local electric utility to estimate your potential savings.
  • Compare system purchase options: Solar panels can be purchased outright or financed over time with a lease or loan. Confirm key financing details like annual percentage rate (APR), fees, payment schedule, and ownership implications when financing solar panels.
  • 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.

The cost of home solar panels in Groton varies depending on several factors, including the size of the system and the type of solar technology being used.

Frequently Asked Questions About Solar in Groton, MA

A solar photovoltaic (PV) system can generate power to run any electric system or appliance in your home. A more specific example is installing a solar water heating system.

With home solar PV, you can save money on your energy bill, lower your home's carbon footprint, and gain additional energy independence.

It depends on your home's location and the kind of panels you plan to use. Groton can experience long, hard winters, so we recommend installing your system in the spring months to maximize your generation for the year.

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. The average annual savings in Groton amount to $1,034.

The specific types of maintenance you need will depend on the type of panels you're using. Regardless of type, you should inspect your panels for damage and clean them regularly. Full-service solar contractors in the Groton area offer multipoint maintenance plans to help you make the most of your panels and keep them healthy for as long as possible.

Net metering is a power purchasing policy that allows solar energy system owners to receive compensation for the amount of energy they put back into the grid. It's available in most states and is a great way to reduce energy costs.

While solar energy might not be ideal for some in wet or dark areas, the latest generation of equipment and energy storage systems could boost your property's solar viability enough to achieve a return on investment. A contractor could also recommend a different primary source of renewable energy like wind or geothermal to boost your generation.
