Methodology: How We Ranked the Best Solar Companies in Hempstead

EcoWatch's solar experts analyzed each solar company in 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 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 Hempstead

The cost of installing a solar panel system has dropped greatly in the past several years, but it's still a substantial investment for most homeowners. The overall price and potential savings vary depending on a few important factors such as:

  • System size and type: Some models are more costly than others, so the one you want to get can raise or lower your initial investment. Plus, the more solar panels you need to get, the more it'll cost.
  • Your city: This influences the average daily sunlight your roof gets, which helps determine how many panels you need.
  • Incentives: The federal solar investment tax credit, which everyone qualifies for, allows you to deduct 30% of the cost of your solar system installation from your federal taxes. Additionally, not including incentives, you can save about $24,000 over 20 years on your energy bills.
  • How much energy costs for you: If your local energy rates are high, there's a good chance you'll see a higher return on your investment in a solar system. In Hempstead, you can save an average of $80 a month on your electricity bills.

Although a solar panel system costs a good chunk of money upfront, it can save you a considerable amount over the lifespan of your panels. The question of how much, though, depends on a number of factors, like the size of your solar panel system and your local electricity rates.

Solar Incentives in Hempstead

There are a lot of reasons why adopting solar power is beneficial. One of them involves some government incentives you can take advantage of. Local solar incentive programs vary by location and, sometimes, utility company. Many states offer rebates for solar panels, in addition to the federal solar tax credit. For detailed information about local incentives, see our article on solar incentives.

Environmental Impact of Switching to Solar in Hempstead

An important reason so many homeowners are considering installing solar panels is to help lower their environmental impact. But how much can installing solar panels actually help the environment? The average person has a considerable carbon footprint. Between their car, which releases over 10,000 pounds of carbon dioxide emissions every year, and energy for their home, it can be overwhelming to figure out what to do. Installing solar panels is a practical thing you can do to help. Though solar panel production emits carbon dioxide, the panels make up for it by considerably reducing the amount of CO2 you would have released if you still used nonrenewable energy. In Hempstead, you can reduce your carbon footprint by 50 pounds a year with solar panels. As you can see, investing in solar has so many other perks apart from saving money. One of the most important ones is that you can help save the environment too.

What are a few of the main advantages and disadvantages of adopting solar power?

The main advantages of solar power are that it can reduce or, in some cases, completely eradicate your electricity bills, raise the value of your home and bring down your carbon footprint. The main disadvantages are that solar panels can be costly to install, you may not save a lot if you don't use a lot of electricity and it doesn't work for all roof types and locations.

Are solar panels worth it?

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

How long do solar panels last?

On average, the lifespan of solar panels is 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 larger level of energy production.
