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
The cost of installing solar panels has dropped immensely over the past several years, but it's still a large investment for most homeowners. There are several factors you should consider when trying to determine costs and your potential savings, such as:
- Incentives: Along with the federal Solar Investment Tax Credit (ITC), which lets you receive a tax credit curretnly worth 30% of your overall installation cost, your state or local government may offer additional tax exemptions, credits or rebates that will help you save even more. Excluding incentives, you can save an average of $24,000 over 20 years with your solar system, too.
- How much you spend on energy: The typical family in Dennis shells out around $1,000 a year on energy use alone, so you could be looking at that much in savings.
- Your income and budget: This shapes what model of solar panels you can buy.
- Energy consumption: Solar may be an expensive option for households that don't need a lot of energy a month.
So is installing solar panels worth it? Whether you're trying to decrease your electric bills, carbon dioxide emissions or both, solar panels are a worthwhile investment for many Dennis homeowners.

Not only can it help preserve the environment, but you can also save a decent amount of money on your installation with various government incentives.

Environmental Impact of Switching to Solar in Dennis
Replacing nonrenewable energy with solar power is a good way to do what you can for a cleaner and more sustainable future. You may be curious — how much does making the switch do for the environment anyway? One thing you should keep in mind is your overall carbon footprint. For example, if you spend a lot of time in the car and have an electric vehicle, you can use solar energy for your home to power your EV and therefore help offset your carbon emissions. In Dennis, the average person can reduce their carbon footprint by 40 pounds a year once they go solar. Since solar energy is plentiful and produces electricity without releasing carbon emissions, adding solar panels to your home is one easy step you can take to help protect the environment.
