Methodology: How We Ranked the Best Solar Companies in Dennis
EcoWatch's solar experts analyzed each solar company in Dennis 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 Dennis
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 Dennis
We understand that for lots of homeowners, the choice to invest in solar depends on installation costs. The cost of solar and the savings it generates vary depending on a few important factors such as:
- The make and model of solar panels you want to get: Higher-efficiency panels have higher prices, so that will shape your budget for your solar project.
- Incentives: The federal solar investment tax credit currently allows you to decrease your taxes by 30% of the project cost. Your state and even local utility companies may also have incentives and rebates that you can use. In addition, you can save about $24,000 over 20 years on your utility bills, before factoring in incentives.
- Electricity consumption: The average home in Dennis doesn't use much energy, and therefore may not see as many savings on their power bills.
- Your current power bills: Solar panels can noticeably reduce, or completely eliminate, your utility bills. In Dennis, you can save an average of $87 a month.
Solar is a profitable investment for most homeowners. You can generate your own electricity instead of paying for it from a utility company and benefit from solar tax credits and rebates, all while helping preserve the Earth.

Solar Incentives in Dennis
Although solar power is typically a big investment, it can save you a lot of money over many years because of smaller power bills and government incentives. State and city solar incentive programs vary by location and, sometimes, utility company. Many states offer rebates for solar panels, in addition to the federal solar tax credit. You can learn about the incentives you can use in our article on solar incentives
Environmental Impact of Switching to Solar in Dennis
One of the best reasons to adopt solar energy is to cut your reliance on nonrenewable energy sources like burning fossil fuels, which are harmful for the environment. A question many might be asking themselves is how much can they really help preserve the environment by switching to solar power anyway? Something that can severely shape 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 decrease your carbon dioxide emissions by charging your car at home. After you go solar, your carbon dioxide emissions can be reduced by about 40 pounds each year. The perks of solar power are plentiful — just like solar power is! That's why so many people have been happy with making the switch to solar.

EcoWatch's Dennis, MA Solar Company Rankings FAQs
Which solar installation company is the best in Dennis?
The best local solar company in Dennis is My Generation Energy, with a rating of 4.01 stars.
What are the best and worst things about solar power?
A few of the biggest pros are that it lowers your power bills, it's environmentally friendly, and it can give you a good return on your investment (ROI). The most notable cons are that solar panels don't produce electricity at night, there is a high upfront cost and solar panels can be an eyesore.
How long does it take for solar to pay for itself?
Solar panels usually pay for themselves in about 8.1 years, but your solar payback period will vary based on your utility costs. The more your typical energy bill, the faster your solar panel system will pay for itself.
How often do solar panels need to be replaced?
Even though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they are completely unusable. What this means is their energy production will have decreased significantly after that point. You can choose to replace them once you've had them for that long or you can continue to use them at a lower efficiency after that time.
