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 key factors to consider when determining whether a solar installer is trustworthy.
Make sure you hire a licensed solar installer. This ensures 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 TrustPilot, the Better Business Bureau (BBB), and Google Reviews to see feedback from past customers on 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.
Call at least three solar companies for free, itemized quotes. A quote should describe all costs and list the solar equipment included. Reviewing multiple quotes helps identify the most cost-effective option for your budget.
Quality solar installations should have strong workmanship and performance warranties. A workmanship warranty covers any installation defects (such as cracks in the panels, poor wiring, or poor alignment), while a performance warranty ensures a certain level of energy production. Strong warranties demonstrate a company's confidence in its work.
Solar energy is great for helping you lower electricity bills over time. Be sure to consider these aspects when considering the final cost and value of solar panels.
In Marlborough, solar panels cost an average of $4,060 per kilowatt, with an average system size of 4.5 kilowatts. The typical Marlborough homeowner spends $12,674 on their solar array after federal tax refunds. An estimate from a local provider will take into account additional information based on your desired system's required preliminary work, size, capacity, and panel type. In some cases, homeowners may prefer leasing solar panels to reduce upfront costs.

A solar photovoltaic (PV) system can generate power to run any electric appliance or system in your home. A more specific example is installing a solar heating system for your water.
There are many advantages of home solar energy. You can reduce emissions, qualify for tax benefits, and save money. With the right storage equipment, solar panels can also offer you additional energy security and offer some protection from power outages.
It depends on your location and what type of panels you're installing. Marlborough 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 Marlborough amount to $967.
The specific types of maintenance you need will depend on the type of panels you're using. Regardless of type, you should clean your panels regularly and inspect them for damage. Full-service solar contractors in the Marlborough area offer comprehensive maintenance plans to help you keep your panels healthy and make the most of your system.
While solar energy might not be the best option for some in wet or dark areas, the latest generation of equipment and energy storage systems could boost 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.
The answer will depend on your specific needs and goals. Generally speaking, monocrystalline solar panels are the most efficient for houses in Marlborough. However, if you have a limited budget, then you could thin-film or polycrystalline solar panels. When you're gathering estimates, make sure to ask about the types of solar panels an installer offers and the benefits and drawbacks of each.
