Methodology: How We Ranked the Best Solar Companies in Rensselaer

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


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 Rensselaer

We understand that for most homeowners, the choice to invest in solar rests on installation costs.Some important factors that influence how much it will cost to install solar panels on your home and how much it could save you over time include:

  • System size and type: Some models are more expensive than others, so the one you decide on can raise or lower your upfront cost. Plus, the more solar panels you need to get, the more it'll cost.
  • Incentives: Something that can save you money on 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 a decent amount of money on your utility bills, which can give you an average of $13,000 of savings over 20 years.
  • Energy consumption: Installing a solar system may be a high-cost investment for homes that don’t consume too much energy a month.
  • Where your home is: This affects how much sunlight your roof receives, which helps determine how many panels you need.

Although a solar panel system costs a sizable chunk of money upfront, it can save you much more in the long term. The question of how much, though, depends on a number of factors, including the angle of your roof and incentives.

Solar Incentives in Rensselaer

Since solar power is better for the environment than fossil fuels, there are some government incentives available to encourage people to make the switch.On top of the federal solar investment tax credit, there are also some state- and city-level benefits, which in almost all cases, can be claimed in addition to the federal incentive, so you can save even more. Take a look at our article on solar incentives to find out what incentives you can take advantage of.

Environmental Impact of Switching to Solar in Rensselaer

A lot of people want to do their part to help the planet, which for many is the main reason for installing a solar system.Something many people might be thinking about is how much can they really help preserve the environment by going solar anyway? Regardless of your location, you can help save the planet by switching to solar energy, but homes that consume lots of energy will have an even bigger impact.In fact, if you make the switch to solar power, you could expect to reduce your carbon dioxide emissions by about 20 pounds each year. If you want to do your part for the environment, you’ll most likely get that there are many benefits of adopting solar power other than just saving money on bills. You can also help preserve the environment, which some would argue is invaluable.

Which solar installation company is the best in Rensselaer?

The highest-rated local solar company in Rensselaer is Kasselman Solar, with a rating of 4.60 stars.

What are some of the advantages and disadvantages of adopting solar power?

A few of the biggest pros are that it reduces your power bills, it’s eco-friendly, and it can provide a good return on your investment (ROI). The most notable cons are that solar panels don’t work as well when there’s limited direct sunlight, the startup costs are high and solar panels can look clunky on your roof.

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

Solar panels generally pay for themselves in about 18.8 years, but your solar payback period will vary based on your utility costs. The more your typical power bill, the quicker your solar panel system will recoup your installation costs.

How efficient are solar panels?

Solar panel efficiency is the amount of energy from the sun that is converted into electricity. Most panels today have an efficiency rating of about 15 to 25%. If your panels are more efficient, you'll need less of them for your home's energy needs.
