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 help the environment by reducing your carbon footprint. When evaluating if a solar provider is a good fit for you, consider these key factors.
Hiring a licensed solar installer is critical. This helps ensure 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 feedback from past customers on local solar companies. Detailed reviews can help you evaluate a company's reliability and customer service. Use caution with companies that have very few reviews or mostly negative ones.
Call three to five solar companies for free, itemized quotes. These quotes should explain all costs and list the solar equipment included. Reviewing multiple quotes helps identify the option that aligns with your budget.
Top-notch solar installations should have strong workmanship and performance warranties. A workmanship warranty covers installation defects, such as cracks in the panels, poor alignment, or poor wiring. A performance warranty ensures a minimum energy output. Comprehensive guarantees indicate that a solar company believes in its work.
Installing solar panels can help lower your electric bills over time. When considering the total price and value of solar panels, make sure to consider these factors.
The cost of home solar panels in Dartmouth varies depending on several factors, including the size of the system and the type of solar technology being used.

A solar photovoltaic (PV) array can generate power to run any electric appliance or system in your home. A more specific example is installing a solar water heating system.
With home solar PV, you can save money on your energy bill, lower your home's carbon footprint, and be better prepared if there's an outage to the local grid.
Yes, it's possible to use home solar energy alongside conventional power sources. In most parts of the country, solar panels are designed to supplement your existing energy sources, meaning that you can reap the environmental benefits and savings of solar energy without having to completely switch over.
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 Dartmouth amount to $1,041.
Your payback period is the time to earn a net profit from your solar panels. It will vary based on the average sunlight in your area, the rate your utility charges per kilowatt of power, and their rated capacity. Dartmouth gets quite a bit of sunlight per day, so an average payback period could last up to 11.8 years per 5 kW of capacity.
Although solar energy is a great option for many, it might not be ideal for homeowners in wet, dark areas. In these cases, you could consider other forms of renewable energy, such as wind or geothermal power, as a primary source. It is also important to speak to a qualified installer to determine if their solar system is compatible with the climate and environment of your area. Even if you choose a different form of renewable energy altogether, you'll still help the environment and could still qualify for distributed generation or other money-saving programs.
The answer ultimately depends on your specific situation. You'll be eligible for a federal tax credit of up to 30% of the system's cost, as well as state or local incentives depending on where you are. As for insurance, you'll need to notify your insurer about your new solar panels. Your premium may increase due to added property values, but you'll have peace of mind if a covered event happens to the system.
