Methodology: How We Ranked the Best Solar Companies in Littleton
EcoWatch's solar experts analyzed each solar company in Littleton based on criteria such as its reputation in the industry, customer reviews, services, warranty coverage and financing. Using this solar methodology, we used the data we collected to rate and rank each company and narrow down our picks for the best solar companies in Littleton
Below are some the criteria we examined specifically for Massachusetts solar companies
- Brand reputation and certifications (20%): We take each company's Better Business Bureau (BBB) score into consideration, as well as how long the installer has been in business (at least 5 years is required, 10 preferred) and what type of solar certifications it holds.
- Customer reviews (20%): Trust is a top priority at EcoWatch, so we take customer experience under close consideration. We scour different review sites and customer testimonials when ranking our top solar companies, checking sites such as Trustpilot and Google Reviews. We also consider any potential complaints or lawsuits filed against these companies and award or remove points accordingly.
- Warranty (20%): A company earns a perfect score in this category if it offers 25-year warranties that cover performance, product and workmanship. The industry standard that we measure companies against is 25-year product and performance warranties, along with a 10-year workmanship warranty. We also look closely into the track record of the post-installation support each company provides in terms of honoring its contracts
- Solar services (10%): All of the companies we review install solar panels, but we award companies higher points if they offer additional services for customers, like battery installation, energy-efficiency audits, and EV chargers.
- Pricing and financing (10%): It's hard to get exact quotes for solar projects, but we use marketplace research to determine how each company prices its equipment and installation services. Additionally, companies that offer more help for panel financing — like in-house loans, leases, or PPAs — score higher than those that don't.
- Availability (10%): The bigger the service area, the higher the company will score.
- Transparency and accessibility (5%): Solar installers that offer free consultations and easy contact methods score higher in this category.
- Environmental, social and corporate governance factors (5%): A company earns a perfect score in this category if it offers public data disclosure, addresses end-of-life (EOL) products or processes, and demonstrates a commitment to uplifting the communities that it serves.
The Cost and Benefits of Solar in Littleton
We get that for many homeowners, the choice to invest in solar rests on installation costs. Some important factors that dictate the cost of installing a solar panel system on your home and how much money you could save over time are:
- System size and type: Some models are more expensive than others, so the one you want to get can raise or lower your upfront cost. Plus, the more solar panels you need to get, the more it'll cost.
- Electricity consumption: The average home in Littleton doesn't use much energy, and so may not see as many savings on their power bills.
- Your home's power bills: Because of fairly high monthly energy bills in Littleton, you could save about $980 a year with solar.
- Incentives: The federal solar investment tax credit currently lets you reduce your taxes by 30% of the project cost. Your state and city may also have incentives and rebates that you can use. Plus, you can save about $21,000 over 20 years on your utility bills, without incentives.
Thanks to the cost of solar panels being lower than before as well as various solar incentives, they are a solid investment for many homeowners.

Solar Incentives in Littleton
In an effort to increase the adoption of solar power, federal, state and local governments — and even some utility companies — offer incentives to help make switching to solar power more financially viable and accessible. Local solar incentives depend on the location and, sometimes, utility company. A lot of states offer rebates for solar panels, in addition to the federal solar tax credit. For comprehensive information about incentives that apply to you, check out our article on solar incentives.
Environmental Impact of Switching to Solar in Littleton
One of the most compelling reasons to embrace solar energy is to reduce your dependence on traditional energy sources like burning fossil fuels, which are destructive for the environment. You may be asking yourself — how much does making the switch do for the planet anyway? One thing that can severely influence your carbon footprint is how long your commute is and how much you drive altogether. If you switch to solar power and drive an electric car, you can vastly lower your carbon dioxide emissions by charging your car at home. In Littleton, the average homeowner can lower their carbon footprint by 40 pounds a year once they go solar. The perks of solar power are abundant — just like solar power is! That's why so many people have been happy with making the switch to solar.

In Littleton, ReVision Energy is the best local solar company. Our team of experts rates it 4.12 stars, so it's a solid choice if you're looking to install solar panels on your house.
What are the pros and cons of solar power?
The biggest advantages of solar power are that it can reduce or, for some, completely erase your electricity bills, improve your home's value and lower your carbon footprint. The biggest disadvantages are that solar panels can be costly to install, you may not save a lot if you don't use a lot of electricity and whether you can install solar panels depends on your roof configuration.
How long does it take for solar to pay for itself?
Solar panels typically pay for themselves in about 9.4 years, but your solar payback period will vary depending on your utility costs. The higher your typical energy bill, the quicker your solar panel system will recoup your installation costs.
How efficient are solar panels?
