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:
Installing solar panels can cut your electricity costs and help the environment by reducing your carbon footprint. When deciding if a solar provider is a good fit for you, consider these key factors.
Make sure you hire a licensed solar installer. This help guarantee that the work is done correctly using current best installation 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 the Better Business Bureau (BBB), TrustPilot, and Google Reviews to see customer feedback about local solar companies. Detailed reviews can help you evaluate a company's dependability and level of service. Use caution with companies that have no reviews or mostly negative ones.
Call 3–5 solar companies for free, itemized quotes. The quotes should explain all costs and specify the solar equipment included. Reviewing multiple quotes helps identify the best option that fits your budget.
Top-notch solar installations should have strong workmanship and performance warranties. A workmanship warranty covers installation defects, such as poor wiring, cracks in the panels, or poor alignment. A performance guarantee ensures a minimum energy output. Comprehensive warranties indicate that a solar company believes in its work.
Solar power can help decrease your electricity costs long-term. When weighing solar panel's cost and value, be sure to consider these considerations.
The average Holliston homeowner will spend around $12,674 on a home solar system after federal tax refunds. Solar arrays in Holliston cost roughly $4,060 per kilowatt, with the average residential solar system being 4.5 kilowatts. A personalized estimate from a local solar provider will include costs for permit fees, labor, and preliminary work, and will account for your system's capacity, panel type, and size. Some homeowners prefer to lease their solar panels in order to reduce upfront costs.

Generally speaking, your energy bills will significantly decrease 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 Holliston, the average amount someone can save is $1,041 per year. With net metering programs offered by many utilities, you could ultimately make a profit from your system when your payback period is done.

Solar energy can be more efficient than other forms of renewable energy. They have low maintenance costs and today's systems can generate and manage energy under more conditions.
