Methodology: How We Ranked the Best Solar Companies in Durham
EcoWatch's solar experts analyzed each solar company in Durham 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 Durham
Below are some the criteria we examined specifically for New Hampshire 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 Durham
We know that for many homeowners, the decision to invest in solar highly depends on installation costs.Some significant things that impact the upfront cost and potential savings over time include:
- System size and type: Some models are more expensive than others, so the one you get can raise or lower your initial investment. Plus, the more solar panels you need to get, the more it'll cost.
- Incentives: The federal solar investment tax credit, which everyone in the U.S. is eligible for, lets you deduct 0 of the cost of installing your solar panel system from your taxes. In addition, not including incentives, you can save about $21,000 over 20 years on your energy bills.
- How much energy you use: If your home regularly uses a lot of energy, you'll see more savings from installing solar panels.
- Your city: This affects how much sunlight your roof receives, which helps determine how many panels you need.
Although a solar panel system costs a sizable chunk of money upfront, it can save you a considerable amount over time. The question of how much, though, depends on a number of factors, like the angle of your roof and your local electricity rates.

Environmental Impact of Switching to Solar in Durham
Swapping traditional energy for solar is a good way to do what you can for a more eco-friendly future.But how much can switching to solar actually affect the environment? One thing to consider is your overall carbon footprint. For example, if you spend a lot of time in the car and have an electric vehicle, you can install solar panels on your home to power your EV and therefore help offset your carbon emissions.Although solar panel manufacturing emits carbon dioxide, the panels make up for it by considerably reducing the amount of CO2 you would have been responsible for if you still used traditional energy. In Durham, you can reduce your carbon footprint by 40 pounds a year with solar panels. For those who want to help the environment, the upfront cost of solar is a small price to pay for reducing your carbon footprint.
