Methodology: How We Ranked the Best Solar Companies in Deer Park

EcoWatch's solar experts analyzed each solar company in Deer Park 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 Deer Park


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 Deer Park

Although solar panels can help save you a decent chunk of change on energy over time, it's necessary to take into consideration the startup costs. A few key factors that affect the cost of installing solar panels on your home and how much it could save you over time are:

  • Incentives: The federal solar investment tax credit, which everyone in the U.S. is eligible for, lets you deduct 30% of the cost of installing your solar panel system from your federal taxes. In addition, not including incentives, you can save about $22,000 over 20 years on your energy bills.
  • Energy consumption: Installing solar panels may be a high-cost investment for homes that don't use a lot of energy each month.
  • Average daily sunlight: Since Deer Park gets a decent amount of average daily sunlight, your solar panels can generally generate enough energy to power your whole home, which affects how much your solar panels can save you on your electricity bills.
  • The make and model of solar panels you want to get: Higher-efficiency panels are more expensive, so that will determine your budget for your solar project.

There are several good benefits of solar despite the initial cost of installation. It can help the environment and your finances. Additionally, it can increase the value of your home, resulting in even more benefits if you decide to sell your home later.

Solar Incentives in Deer Park

If you're thinking about switching to solar energy, several government incentives and tax credits can drastically bring down the cost of the project and expedite the return on your investment. State and city solar incentives vary by location and, sometimes, utility company. Many states offer rebates for home solar power systems, in addition to the federal solar tax credit. Our article on solar incentives goes over more detailed information on the incentives you can find in Deer Park.

Environmental Impact of Switching to Solar in Deer Park

Replacing nonrenewable energy with solar power is a compelling way to do what you can for a more environmentally-friendly future. A question many people might be wondering about is how much can they really help protect the environment by going solar anyway? In Deer Park, where the energy generation produces a lot of greenhouse gasses, going solar can have a significant effect on the environment since solar power has a lower carbon footprint. In fact, if you install solar panels, you could reduce your carbon dioxide emissions by about 100 pounds each year. Since solar power is renewable and makes electricity without free from carbon dioxide emissions, making the switch to solar power is one easy step you can take to help preserve the planet.

What are the pros and cons of solar power?

The advantages of solar power are that it can decrease or, for some, completely eradicate your electricity bills, raise your home's value and bring down your carbon footprint. The disadvantages are that solar panels can be costly to install, you may not save as much if you don't use a lot of electricity and whether you can install solar panels depends on your roof configuration.

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

Solar panels generally pay for themselves in about 9.0 years, but your solar payback period will vary depending on your utility costs. The higher your typical energy bill, the faster your solar panel system will pay for itself.

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

Solar panel capacity is rated depending on how many watts of power they produce under standard testing conditions. Since each panel can typically produce about 250 to 400 watts per hour, the average house will need 20 to 35 panels.
