Methodology: How We Ranked the Best Solar Companies in Collinsville
EcoWatch's solar experts analyzed each solar company in Collinsville 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 Collinsville
Below are some the criteria we examined specifically for Connecticut 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 Collinsville
The cost of installing solar panels has decreased significantly over the past several years, but it’s still a substantial investment for most homeowners.Some important things that affect how much it will cost and how much you could save include:
- Incentives: One thing that can reduce the cost of your solar project is the solar investment tax credit (ITC), which is a tax credit that lets you deduct from your taxes a percentage of the project cost. You can also save money on your utility bills, which can generate an average of $22,000 of savings over 20 years.
- Choice of solar panels: The kind of solar panels you get will affect your total cost. High-efficiency monocrystalline panels are more expensive upfront but can also save you more money over the lifetime of your system. If you don’t need to maximize efficiency, you can opt for a higher number of more affordable panels.
- Average daily sunlight: Since Collinsville gets a decent amount of average daily sunlight, your solar panels can generally generate enough energy to power your whole home, which impacts how much your electricity bills will be.
- Your current power bills: Solar panels can greatly reduce, or completely eradicate, your utility bills. In Collinsville, you can save an average of $1,844 a month.
There are several good benefits of solar in spite of the initial cost of installation. It can help the Earth and your bank account. In addition, it can raise the value of your home, resulting in even more benefits if you decide to sell your home later.

When should I put up solar panels?
Although summer is the most popular time people install solar panels, the best time is actually winter. You can save money since there's decreased demand during the winter months, and it allows you to be up and running with solar for the higher power bills you may get during the summer.
