Methodology: How We Ranked the Best Solar Companies in Caldwell

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


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 Caldwell

For many people, the decision of which solar company to hire depends on total costs.A few main factors that determine how much it will cost to install a solar panel system on your home and how much it could save you over time are:

  • The amount of sunlight your roof gets: If your rooftop gets limited direct sunlight, your solar panel system won’t be able to generate as much energy, which will give you lower savings on energy bills than someone with a roof that gets plenty of sunlight.
  • The model of solar panels you have the money for: This is dependent on how much you’re willing to spend upfront.
  • Incentives: Something that can make your solar project cost less is the solar investment tax credit (ITC), which is a tax credit that’s equal to a percentage of the project cost. You can also save money on your utility bills, which can generate an average of $14,000 of savings over 20 years.
  • Energy consumption: Installing solar panels may be a high-cost investment for families that don’t need a good amount of energy per month.

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

What is the best solar installation company in Caldwell?

The top local solar company in Caldwell is Kamtech Solar Solutions, with a rating of 4.80 stars.

What are the advantages and disadvantages of solar power?

A few of the biggest pros are that it lets you spend less on your electricity bills, it’s environmentally friendly, and it can provide a decent return on your investment (ROI). The most notable cons are that solar panels don’t work as well when there’s limited direct sunlight, there is a high upfront cost and solar panels can look clunky on your roof.

Is it worth installing solar panels on my home?

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

What is solar panel capacity and how much do I need for my house?

Solar panel capacity is the amount of energy the panels can produce under ideal conditions (a sunny day around noon). The average household has to install between 20 and 35 panels to cover how much energy they need.
