Methodology: How We Ranked the Best Solar Companies in Lambertville

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


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 Lambertville

Solar panels run off a free energy source — the sun — but to take advantage of this you will first need to pay to install your panels.The installation cost is just one important factor you should bear in mind when looking into installing solar panels. How much it'll cost and how much you can save depend on things such as:

  • How much power your household consumes: Homes that use plenty of power each month may call for more solar panels and, therefore, be more expensive, but will also benefit more over time.
  • Average daily sunlight: Since Lambertville gets a decent amount of average daily sunlight, your solar panels can generally generate enough energy to power your whole home, which impacts how much your electricity bills will be.
  • System size and type: Some models are more pricy than others, so the one you want can raise or lower your upfront cost. Plus, the more solar panels you need to get, the more it'll cost.
  • Your current electricity bills: Solar panels can greatly reduce, or totally eradicate, your utility bills. In Lambertville, you can save an average of $1,059 a month.

As a result of solar panels decreasing in cost as well as various solar incentives, they are a worthwhile investment for many homeowners.

What is the top solar panel installer in Lambertville?

The top local solar company in Lambertville is Exact Solar, with a rating of 5.00 stars.

What are the major pros and cons of adopting solar power?

The biggest advantages of solar power are that it can decrease or, for some, 100% eradicate your electricity bills, raise the value of your home and lower your carbon footprint. The greatest disadvantages are that solar panels can be pricey to install, you may not save as much if you don’t use a lot of electricity and it doesn’t work for all roof types and locations.

How long does it take for solar to pay for itself?

Solar panels usually pay for themselves in about 18.2 years, but your solar payback period will vary depending on your utility costs. The more your typical power bill, the faster your solar panel system will recoup your installation costs.

How often do solar panels need to be replaced?

On average, solar panels can last about 25 to 30 years. Some even last up to 50 years, but efficiency decreases by about 0.8% each year. You can choose to replace them sooner if you want to maintain a higher amount of energy production.
