Methodology: How We Ranked the Best Solar Companies in Hillside

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


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.

High-efficiency monocrystalline panels will cost more upfront but can also lead to more savings over the lifetime of your system.

  • Incentives: Along with the federal Solar Investment Tax Credit (ITC), which lets you receive a tax credit curretnly worth 0 of your overall installation cost, your local government may offer additional tax exemptions, credits or rebates that will help you save even more. Excluding incentives, you can save an average of $15,000 over 20 years with your solar panels, too.
  • average energy usage: The more electricity your household consumes on average and the steeper your current electricity bills are, the more likely you'll benefit from making the switch to solar.
  • The amount of sunlight your rooftop gets: Because of Hillside’s high amount of average daily sunlight, you should be able to save a decent amount on your energy bills.

One reason so many homeowners are considering switching to solar power is to help reduce their environmental impact.But – how much exactly can you help the planet by using solar power? A key thing to keep in mind is your overall carbon footprint. For example, if you spend a lot of time driving to work, your footprint may be larger, so adopting solar power for your home can help offset that.Even though making solar panels emits carbon dioxide, the panels make up for it by significantly lowering the amount of CO2 you would have released if you still used nonrenewable energy.

Since energy from the sun is renewable and makes electricity without releasing carbon emissions, adding solar panels to your home is one easy step you can take to help preserve the planet.
