Methodology: How We Ranked the Best Solar Companies in Lawrenceville

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


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 Lawrenceville

While solar panels can help save you money on electricity bills over time, it’s important to consider the startup costs.A few main factors that dictate the cost of installing solar panels on your home and how much it could save you over time include:

  • Choice of solar panels: The kind of solar panels you get will affect your total cost. High-efficiency monocrystalline panels are more expensive upfront but can also lead to more savings over the lifetime of your system. If you don’t need to maximize efficiency, you can go with a higher number of more affordable panels.
  • Typical energy usage: The more power your household uses on average and the higher your current power bills are, the more likely you'll benefit from switching to solar.
  • Your current energy bills: Solar panels can substantially lower, or entirely eliminate, your utility bills. In Lawrenceville, you can save an average of $1,422 a month.
  • The amount of sunlight your roof gets: If your roof doesn’t see much direct sunlight, your solar panels won’t be able to generate as much energy, which will leave you with lower savings on power bills than someone with a roof that gets lots of sunlight.

Solar is a fruitful investment for most homeowners. You can make your own power instead of paying for it from a utility company and take advantage of solar incentives and rebates, all while helping the Earth.

Solar Incentives in Lawrenceville

Since solar power is better for the environment than traditional energy sources, there are several government incentives in place to encourage its adoption.On top of the federal tax credit incentive, there are also some state- and city-level benefits, which in almost all cases, stack with the federal incentive, so you get to save even more. Our article on solar incentives goes over more information on the incentives you can benefit from in Lawrenceville.

Environmental Impact of Switching to Solar in Lawrenceville

If you’re thinking of adding solar panels to your home, one of the major reasons why may be to lower your carbon dioxide emissions.But how much can installing solar panels actually affect the environment? One thing to consider is your overall carbon footprint. For example, if you spend a lot of time in the car and have an electric vehicle, you can use solar energy for your home to power your EV and therefore help offset your carbon emissions.In Lawrenceville, the average person can lower their carbon footprint by 60 pounds a year once they go solar. As you can see, trading traditional energy for solar has so many other perks beyond saving money. One of the most important ones is that you can help save the Earth too.

EcoWatch's Lawrenceville, NJ Solar Company Rankings FAQs

What is the top solar company in Lawrenceville?

The top local solar company in Lawrenceville is SunPower, with a rating of 4.10 stars.

Are solar panels actually eco-friendly?

Making solar panels requires chemicals and produces toxic waste that can be dangerous for the environment, which is the main drawback of solar panels.

Is it worth putting solar panels on my roof?

Solar panels can be a beneficial investment for many homeowners, but frankly, they might not be worth it for everyone. If your home doesn't get a lot of direct sunlight or your energy bills are already reasonably low, solar panels might not be for you.

What is the best kind of solar panel?

The different types of solar panels are monocrystalline, polycrystalline and thin-film. Monocrystalline panels are more efficient but also more costly. Polycrystalline panels are less expensive but also less efficient than monocrystalline. Thin-film solar panels are flexible, so they can be used where the other kinds can’t, like on curved surfaces or cars, but they are also less efficient. The best one for you depends on your budget, roof layout and desired energy output.
