Methodology: How We Ranked the Best Solar Companies in Union

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


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 Union

The cost of installing solar panels has decreased immensely in the past few years, but it’s still a substantial investment for most homeowners.Some main factors that affect how much it will cost to install solar panels on your home and how much it could save you over time are:

  • Choice of solar panels: The type of solar panels you buy will affect your total cost. High-efficiency monocrystalline panels will cost more 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.
  • 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 result in an average of $14,000 of savings over 20 years.
  • Where your home is: This affects how much sunlight your roof receives, which helps determine how many panels you need.
  • Your home's power bills: Because of high monthly power bills in Union, you could save about $1,100 a year with solar.

There are lots of wonderful benefits of solar even with the initial cost of installation. It can help the environment and your bank account. Additionally, it can raise the value of your home, giving you even more benefits if you choose to sell your home later.

Environmental Impact of Switching to Solar in Union

One of the best reasons to use solar power is to minimize your reliance on traditional energy sources like burning fossil fuels, which are damaging for the environment.But how much can installing solar panels actually affect the environment? An important thing to think about is your overall carbon footprint. For example, if you spend a lot of time driving to work, your footprint may be larger, so switching to solar power for your house can help offset that.Though making solar panels releases carbon dioxide emissions, the panels make up for it by significantly reducing the amount of CO2 you would have released if you still used traditional energy.

One of the main ones is that you can help save the planet too.

EcoWatch's Union, NJ Solar Company Rankings FAQs

What is the best solar panel installer in Union?

The highest-rated local solar company in Union is SunPower Master Dealer SOLAR, with a rating of 3.00 stars.

What is the negative environmental impact of making solar panels?

Solar panels can be harmful for the environment when manufacturers use toxic chemicals in the construction. Chemicals can make solar panels difficult to dispose of safely once they’ve reached the end of their lifespan. Solar panel manufacturing requires a lot of energy as well. The energy payback period is about 1 to 4 years.

Are solar panels worth it?

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

What is the efficiency of solar panels?

Solar panel efficiency is the amount of energy from the sun that is converted into electricity. Most panels today have an efficiency rating of about 15 to 25%. If your panels are more efficient, you'll need fewer of them to meet your home's energy needs.
