Methodology: How We Ranked the Best Solar Companies in Allendale

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


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 Allendale

For most homeowners, whether or not you should invest in a solar energy system boils down to the cost.There are quite a few factors you should consider when trying to determine costs and your potential savings, such as:

  • Your city: This influences how much sunlight your roof gets, which helps determine how many panels you need.
  • Energy consumption: Installing a solar system may be too pricey an investment for households that don’t use a lot of energy a month.
  • The kind of solar panel system you have the money for: This is dependent on your income and budget.
  • Your power bills: This will dictate your savings. In Allendale, the average homeowner can save about $1,400 a year on their electricity bills.

Thanks to solar panels decreasing in cost as well as local and federal solar incentives, they are a solid investment for the majority of homeowners.

Environmental Impact of Switching to Solar in Allendale

One of the most compelling reasons to adopt solar energy is to reduce your dependence on nonrenewable energy sources like burning fossil fuels, which are harmful for the environment.You may be asking yourself – how much does going solar help the environment anyway? Something that can severely shape your carbon footprint is your commute time and how much you drive altogether. If you install solar panels and have an electric car, you can greatly decrease your carbon dioxide emissions by charging your car at home.Since solar panels don’t release greenhouse gas emissions into the atmosphere when generating electricity, they’re a good substitute for nonrenewable energy sources. In fact, you could lower your carbon dioxide emissions by about 60 pounds each year. If you want to do what you can for the environment, you’ll likely find that there are many benefits of adopting solar power other than just saving money on electricity. You can also help protect the environment, which some would argue is invaluable.

EcoWatch's Allendale, NJ Solar Company Rankings FAQs

What is the best solar panel installer in Allendale?

The highest-rated local solar company in Allendale is SSAY Solar Savings All Year, with a rating of 5.00 stars.

What are the pros and cons of solar power?

The greatest advantages of solar power are that it can lower or, in some cases, completely erase your electricity bills, improve your home’s value and cut back on your carbon footprint. The main disadvantages are that solar panels can be expensive to install, you may not see as many savings if you don’t use a lot of electricity and it doesn’t work for all roof types and locations.

Is it worth putting solar panels on my roof?

Solar panels can be a great investment for many homeowners, but admittedly, they might not be worth it for everyone. If your home doesn't get enough sunlight or your power bills are already pretty low, solar panels might not be for you.

When is the best time of year to install solar panels?

Although summer is the most common time people install solar panels, the optimal time is actually winter. You can save money since there's not as much 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.

Our goal is to reach as many people as we can with sensible solutions like solar energy. Our team of full-time local researchers collects solar price and installation data for every city in America then compiles it to create these digestible city guides.
