Methodology: How We Ranked the Best Solar Companies in West Windsor
EcoWatch's solar experts analyzed each solar company in West Windsor 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 West Windsor
Below are some the criteria we examined specifically for New Jersey 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 West Windsor
When deciding on a solar company, most homeowners or business owners think about the costs above all.A few key factors that determine how much it will cost to install solar panels on your home and how much money you could save over time are:
- How much you spend on energy: The average family in West Windsor pays around $1,200 a year on home energy use alone, so you could gain that much in savings.
- Energy consumption: Solar may be a high-cost investment for families that don’t consume a lot of energy a month.
- The kind of solar panel system you can afford: This depends on what your budget is.
- Incentives: Something that can make your solar project cost less 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 power bills, which can generate an average of $14,000 of savings over 20 years.
So are solar panels worth it? Whether you hope to lower your electricity costs, carbon emissions or both, solar panels are a good investment for many West Windsor homeowners.

Environmental Impact of Switching to Solar in West Windsor
An important reason so many people are considering switching to solar power is to help bring down their environmental impact.But – how much exactly can you help the planet by making the switch to solar? No matter where you are, you can help the planet by switching to solar energy, but homes that use lots of energy will have an even greater impact.Since solar panels don’t release CO2 emissions into the atmosphere when creating electricity, they’re a good substitute for traditional energy sources. In fact, you could lower your carbon dioxide emissions by about 60 pounds each year. For homeowners who are concerned about the environment, the upfront cost of solar is a small price to pay for offsetting your carbon emissions.

EcoWatch's West Windsor, NJ Solar Company Rankings FAQs
Which solar company is the best in West Windsor?
The best local solar company in West Windsor is Exact Solar, with a rating of 5.00 stars.
What are the best and worst things about solar power?
The advantages of solar power are that it can reduce or, in some cases, 100% cut your electricity bills, raise the value of your home and bring down your carbon footprint. The 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 for solar to pay for itself?
The average payback period for solar panel installation is about 16.8 years, but the exact period varies by local electricity costs, incentives and net metering programs.
How long do solar panels last?
Even though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they should be disposed of. What this means is their energy production will have decreased by about 0.8% each year since installing them. You can decide 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.
