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 reduce your electricity costs and benefit the planet by reducing your carbon footprint. When determining whether a solar provider is the best option for you, consider these key factors.
Confirm that your solar installer is properly licensed. This ensures that the work is done properly using the most up-to-date installation methods. To install a new photovoltaic system in Minnesota, a contractor must have an electrician or electrical contractor license from the Department of Labor and Industry, along with a residential building or remodeling contractors' license in some cases. If their work is regulated by the state's Mechanical Code, they must carry a $25,000 minimum bond with the Department of Labor and Industry.
Look at review platforms such as Google Reviews, TrustPilot, and the Better Business Bureau (BBB) to find out what previous customers have to say about local solar companies. Reviews can give you an idea of a company’s trustworthiness and customer service. Be cautious of companies lacking reviews or with predominantly negative feedback.
Contact at least three solar companies to receive free, detailed quotes. Quotes should clearly explain all costs and list the exact solar components included. By comparing multiple quotes, you can identify the option that best fits your budget.
Top-notch solar installations should come with strong workmanship and performance guarantees. A workmanship warranty covers installation defects, such as poor alignment, poor wiring, or cracks in the panels. A performance warranty ensures a minimum energy output. Comprehensive warranties show that a solar company believes in its work.
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.
Cambridge homeowners typically spend about $20,229 on home solar systems after federal tax refunds. Solar arrays in Cambridge cost approximately $4,030 per kilowatt, with the average residential solar system being 7.2 kilowatts. A personalized estimate from a local solar provider will include costs for permit fees, preliminary work, and labor, and will account for your system's panel type, capacity, and size. Some homeowners prefer to lease solar panels in order 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.
With home solar energy, you can recoup the cost of the system over time, lower your home's carbon footprint, and gain additional energy independence.
It depends on where you live and the kind of panels you plan to use. Cambridge can experience long, hard winters, so we recommend installing your system in the spring months to maximize your generation for the year.
Of course. Cambridge uses an even mixture of solar energy and conventional power sources. While your panels at home will lower your home's emissions and provide cost savings, you'll still benefit from access to the local grid.
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 Cambridge, the average amount someone can save is $1,519 per year. With net metering programs offered by many utilities, you could ultimately make a profit from your system after the payback period concludes.
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.
Absolutely. Solar panels are independent of the Cambridge grid and will continue to generate power even if the grid is having problems. Keep in mind, however, that a solar system without a storage system cannot keep you running through a nighttime outage. 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.
Some frequently-used types of home solar panels in Cambridge include polycrystalline, thin-film and monocrystalline. Monocrystalline panels are balanced and efficient, while polycrystalline and thin-film panels pair good performance with greater upfront value. Ask your local provider about the types of solar panels they work with.
