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 save money on electricity costs and help the planet by reducing your carbon footprint using renewable energy. Here are some crucial factors to consider when evaluating if a solar installer is trustworthy.
It's important to hire a licensed solar installer. This ensures that the work is done correctly 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 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 very few reviews or mostly negative ones.
Contact at least three solar companies to get free, detailed quotes. Quotes should clearly explain all costs and specify the exact solar components included. By comparing multiple quotes, you can identify the most cost-effective option for you.
Quality solar installations should come with comprehensive workmanship and performance guarantees. The workmanship warranty covers any installation issues such as cracks in the panels, poor wiring, or poor alignment. The performance warranty ensures a specific energy output level. Strong guarantees indicate that a solar installer has faith in its installations.
Solar energy can help you lower electricity bills over time. Be sure to consider these aspects when considering the final cost and value of solar panels.
Solar panel costs vary based on your system's capacity and the solar technology used. The typical Sudbury solar array has a capacity of 4.5 kilowatts. Homeowners in the area should expect to pay around $4,060 per kilowatt; the average Sudbury homeowners spends about $12,674 on a new solar array after accounting for federal tax breaks. (Some homeowners prefer to lease solar panels to reduce upfront costs.) A personalized quote from a local solar company will account for things like the capacity, size, and panel type of the planned system, and should include prices for labor, permit fees, and preliminary work.

Generally speaking, a solar photovoltaic (PV) array can be used to power any household system or appliance that uses electricity. In the smallest case, you can use a solar water heating system.
With home solar energy, you can recoup the cost of the system over time, lower your property's emissions, and gain additional energy independence.
Yes. The grid in Sudbury 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.
Generally speaking, your energy bills will decrease significantly after you install solar panels. This is because you're using the energy you generate for free rather than buying it from your power company. In Sudbury, the average amount someone can save is $995 per year. With net metering programs offered by many utilities, you could ultimately make a profit from your system once the payback period passes.
Net metering is a power purchasing policy that allows solar energy system owners to receive bill credits or payments 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 the best option for some in dark or wet areas, the latest generation of equipment and energy storage systems could increase your property's solar viability enough where you could 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.
Yes, solar panels will still be able to generate energy during a grid outage. To ensure that your solar system is able to keep working during a power outage, make sure to choose a quality solar provider and look for a solar system that includes a battery backup.
