Methodology: How We Ranked the Best Solar Companies in Cornwall

EcoWatch's solar experts analyzed each solar company in Cornwall 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 Cornwall


Below are some the criteria we examined specifically for New York 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 Cornwall

Solar panels run off a free energy source — the sun — but to take advantage of this you will need to pay to install your system. The installation cost is just one important factor you should take into account when looking into getting solar panels. How much it'll cost and how much you can save depend on things such as:

  • How much you spend on energy: The average family in Cornwall spends around $970 a year on electricity alone, so you could be looking at that much in savings.
  • The model of solar panels you want: More efficient models are more costly, so that will determine your budget for your solar project.
  • Incentives: Tax-paying citizens who install a solar energy system this year can save 30% of their installation costs by using the federal solar investment tax credit. You can also save about $21,000 on your electricity bills over 20 years without incentives.
  • Your location: This affects how much sunlight your roof receives, which helps determine how many panels you need.

There are many good benefits of solar even with the upfront cost of installation. It can help the Earth and your finances. Plus, it can increase the value of your home, giving you even more benefits if you decide to sell your home later.

Solar Incentives in Cornwall

Switching to solar power has a lot of great benefits. Not only can it help preserve the Earth, but you can also save a decent amount of money on your installation with various government incentives. These incentives normally consist of cash rebates, tax benefits and/or performance-based incentives. They can cut the cost you pay for installing solar panels by 30%, upwards of 50% in some cases. For comprehensive information about incentives that apply to you, check out our article on solar incentives.

Environmental Impact of Switching to Solar in Cornwall

Lots of people want to do their part for the planet, which often is the primary reason they're interested in installing a solar system. But — how much exactly can you help the environment by making the switch to solar? In a place like Cornwall where commute times can be very long, using solar power can help help reduce the carbon footprint of driving. In fact, if you install solar panels, you could expect to reduce your carbon dioxide emissions by about 20 pounds each year. For homeowners who care about the environment, the upfront cost of solar is a small price to pay for the offset carbon emissions.

EcoWatch's Cornwall, NY Solar Company Rankings FAQs

Which solar panel installer is the best near me?

The top local solar company in Cornwall is Apex Solar Power, with a rating of 3.00 stars.

What are the main advantages and disadvantages of installing solar panels?

The biggest advantages of solar power are that it can reduce or, for some, completely cut your electricity bills, improve the value of your home and bring down your carbon footprint. The biggest disadvantages are that solar panels can be pricey 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 to see a return on your investment after getting solar panels?

The average payback period for solar panel installation is about 9.2 years, but the exact period is influenced by local electricity costs, incentives and net metering programs.

How often do solar panels have to be replaced?

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 after having them for that long or you can keep using them at a lower efficiency after that time.
