Methodology: How We Ranked the Best Solar Companies in New Hempstead

EcoWatch's solar experts analyzed each solar company in New Hempstead 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 New Hempstead


Below are some the criteria we examined specifically for New York 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 New Hempstead

The cost of installing solar panels has dropped immensely in the past few years, but it’s still a large investment for most homeowners.There are a few factors you should consider when trying to determine how much it will cost and how much you can save, such as:

  • Your income and budget: This guides what kind of solar panels you can buy.
  • 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’s equal to a percentage of the project cost. You can also save money on your power bills, which can result in an average of $24,000 of savings over 20 years.
  • Your city: This influences how much sunlight your roof receives, which helps determine how many panels you need.
  • How much electricity your home consumes: Homes that use lots of electricity each month may need more solar panels and, as a result, more upfront cost, but will also save more on their energy bills over time.

So is buying solar panels worth it? Whether you’re trying to reduce your electricity costs, carbon emissions or both, solar panels are a worthwhile investment for many New Hempstead homeowners.

Environmental Impact of Switching to Solar in New Hempstead

EcoWatch's New Hempstead, NY Solar Company Rankings FAQs

What is the top solar panel installer in New Hempstead?

The highest-rated local solar company in New Hempstead is SunPower by New York State Solar Farm, with a rating of 4.80 stars.

What is the negative environmental impact of solar panel manufacturing?

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

How long does it take to see a return on your investment after getting solar panels?

Solar panels typically pay for themselves in about 10.0 years, but your solar payback period will depend on your utility costs. The higher your typical electricity bill, the quicker your solar panel system will recoup your installation costs.

What is the best type of solar panel?

The different types of solar panels are monocrystalline, polycrystalline and thin-film. Monocrystalline panels are more efficient but also more expensive. Polycrystalline panels cost less but also less efficient than monocrystalline. Thin-film solar panels are flexible, so they can be used where the other types can’t, such as on curved surfaces or cars, but they are also less efficient. The best one for you depends on your budget, roof layout and how much efficiency you're looking for.
