Today's Homeowner looks at dozens of datapoints on solar companies to come up with our data-driven rankings. It's not possible for a company to pay for preferential treatment in our rankings. We look at the following key factors in determining who should top our list:
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.
Confirm that your solar installer is properly licensed. This helps ensure that the work is done correctly using current installation best practices. Massachusetts requires new solar photovoltaic systems in the Commonwealth to be installed by a licensed electrician and new solar water heaters to be installed by a construction supervisor.
Check review sites like Google Reviews, TrustPilot, and the Better Business Bureau (BBB) to see feedback from past customers on local solar companies. Detailed reviews can help you assess a company's dependability and customer service. Use caution with companies that have very few reviews or mostly negative ones.
Get free, detailed quotes from 3–5 solar companies. A quote should outline all costs and identify the exact solar parts included. Looking at several quotes can help you find the most cost-effective option.
High-quality solar installations should include robust workmanship and performance guarantees. The workmanship warranty covers any installation issues like poor alignment, cracks in the panels, or poor wiring. The output guarantee ensures an energy generation baseline. Strong warranties reflect a solar provider's confidence in its installations.
Going solar can help decrease your energy expenses. Be sure to evaluate these aspects when judging the cost and value of solar panels.
Wellesley homeowners typically spend about $12,529 on home solar systems after federal tax refunds. Solar arrays in Wellesley cost approximately $4,060 per kilowatt, with the average residential solar system being 4.4 kilowatts. A personalized estimate from a local solar provider will include costs for labor, preliminary work, and permit fees, and will account for your system's panel type, size, and capacity. Some homeowners prefer to lease solar panels to reduce upfront costs.

A solar photovoltaic (PV) array can generate power to run any electric system or appliance in your home. More specifically, you can install a solar heating system for your water.
There are a number of benefits to home solar energy. You can raise your property values, save money, and reduce emissions. With the right storage equipment, solar panels can also offer you further energy independence and offer some protection from power outages.
It depends on your location and what type of panels you're installing. Wellesley 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 Wellesley amount to $1,008.
Your recommended maintenance will vary based on the type of solar panels you have. At a minimum, you should clean and inspect each panel once a quarter. Your solar installation company might offer comprehensive plans where they'll do the maintenance on your behalf.
Regarding taxes, the federal government offers a tax credit of up to 30% of the panels' cost. Depending on where you live, you could also claim or apply for state or property tax incentives. As for insurance, your monthly premium may be slightly higher because solar panels increase your property's value. You should speak with your accountant or insurance agent for information specific to your case.
