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 lower 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 properly using the most up-to-date installation methods. 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 Google Reviews, TrustPilot, the Better Business Bureau (BBB), and other review sites to see what past customers have to say about local solar companies. Detailed reviews on these platforms can help you assess a provider's trustworthiness and customer service. Stay away from companies with few or mainly poor reviews.
Get free, detailed quotes from at least three solar companies. The quotes should list all costs and identify the solar parts included. Looking at several quotes can help you find the option that best fits your budget.
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 faith in its installations.
Going solar can help decrease your energy expenses. Be sure to weigh these aspects when determining the cost and value of solar panels.
The average Millis homeowner will spend around $12,529 on a home solar system after federal tax refunds. Solar arrays in Millis cost roughly $4,060 per kilowatt, with the average residential solar system being 4.4 kilowatts. An estimate from a local solar provider will include costs for preliminary work, labor, and permit fees, and will account for your system's panel type, capacity, and size. Some homeowners prefer to lease their solar panels to reduce upfront costs.

Generally speaking, a solar photovoltaic (PV) system can be used to power any household system or appliance that uses electricity. In the smallest case, you can use a solar water heater.
With home solar PV, you can save money on your energy bill, lower your home's carbon footprint, and gain additional energy independence.
Yes, it's possible to use home solar energy alongside conventional power sources. In most parts of the country, solar panels are designed to supplement your existing energy sources, which means you can reap the environmental benefits and savings of solar energy without having to completely switch over.
Your payback period is the time to achieve an ROI on your solar panels. It will vary based on their rated capacity, the rate your utility charges per kilowatt of power, and the average sunlight in your area. Millis gets quite a bit of sunlight per day, so an average payback period could last up to 12.0 years per 5 kW of capacity.
Net metering is a type of "power purchase agreement." If your state or utility offers net metering, you can send the solar energy you don't use to your provider. In return, they'll give you a credit on your power bill.
Absolutely. Solar panels exist independently from the power grid in Millis and will continue to generate power even if the grid is having problems. Keep in mind, however, that a solar system won't take you through a nighttime outage if you don't have a storage system. Your contractor can discuss some economical options to keep your home's power access reliable through the worst conditions, including battery backups or an emergency generator.
