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:
Going solar can be a great way to lower electricity costs and help the environment by reducing your carbon footprint using renewable energy. Here are some key factors to consider when deciding if a solar installer is reliable.
It's imperative that your solar installer has the proper licensing. This ensures 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.
Check review sites like TrustPilot, the Better Business Bureau (BBB), and Google Reviews 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.
Get free, detailed quotes from at least three solar companies. The quotes should list all costs and identify the solar parts included. Comparing several quotes can help you find the best value for your budget.
Quality solar installations should come with strong workmanship and performance warranties. A workmanship guarantee covers any installation defects (such as poor wiring, cracks in the panels, or poor alignment), while a performance guarantee ensures a certain level of energy production. Strong warranties demonstrate a company's confidence in its work.
Solar panels can help decrease your electricity costs long-term. When weighing solar panel's cost and value, be sure to weigh these considerations.
The average Chelmsford homeowner will spend around $12,674 on a home solar system after federal tax refunds. Solar arrays in Chelmsford cost roughly $4,060 per kilowatt, with the average residential solar system being 4.5 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, size, and capacity. Some homeowners prefer to lease their solar panels to reduce upfront costs.

A solar photovoltaic (PV) system can generate power to run any electric appliance or system in your home. More specifically, you can install a solar water heating system.
There are a number of benefits to home solar energy. You can raise your property values, reduce emissions, and save money. With the right storage equipment, solar panels can also offer you further energy independence and offer some protection from power outages.
Of course. The grid in Chelmsford 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.
You might be pleasantly surprised at how short it takes to get a return on investment from your solar panels. The sun shines frequently in Chelmsford, meaning your payback period could last 12.2 years per 5 kW of capacity on the high end.
Of course. Solar panels don't depend on the grid to work 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.
The answer will depend on your specific needs and goals. For a typical home, monocrystalline solar panels are the most efficient for Chelmsford homes. However, if you have a limited budget, then you could polycrystalline or thin-film solar panels. When you're gathering estimates, make sure to ask about the brand names and models of solar panels a company offers and the benefits and drawbacks of each.
