Best Solar Panel Installation Companies on Long Island
New York's wealth of state-level solar incentives extends to Long Island too. Here's how to access these benefits and choose the best solar installer in the area.
If you live on Long Island, New York, now may be a good time to go solar.
Solar energy usage has soared throughout the whole state of New York, with Gov. Kathy Hochul recently announcing that more than 2 gigawatts of solar energy have been added to the community grid, enough to power almost 400,000 homes. This is one component in a wider Empire State goal of having carbon-free energy by 2040.
Overall, New York state ranks eighth nationwide in terms of solar energy usage, with just over 870,000 homes powered by solar energy and nearly 5% of the state's electricity powered by solar energy, according to the Solar Energy Industries Association. The Empire State offers a state tax credit, net metering policy and sales tax exemption on solar panels.

Freedom Forever also extends a couple of products that take some of the pain and risk out of going solar, like a production guarantee and an escrow option with cash purchases.

Tesla Solar
Most affordable
Read full reviewTesla's solar branch seems to be the least loved of Elon Musk's ventures. Even Tesla's Solar Roof seems to get more love.
If price is the thing you won't budge on, consider Tesla. By all accounts, Tesla installs quality panels and makes the closest thing there is to a household name in solar storage: the Powerwall.
Where you might miss out is customer service. Discussion online seems to suggest Tesla's service is a bit of a gamble.

Momentum Solar
All in-house installers
Read full reviewMomentum installs in 11 states without using subcontractors. While using in-house installers doesn't guarantee a better experience, it does suggest you're likely to get a more uniform experience from Momentum. The fact that Momentum backs its installations with a 25-year workmanship warranty hints at a strong belief in its crews' ability. If Momentum is part of your search, consider the warranties against leaks that other companies offer. Momentum's is five years, which isn't the best.

Cost of solar panels in Long Island
"The first advantage and benefit of going solar is that in most cases you save money," said Shyam Mehta, the assistant director of distributed energy resources at the New York State Energy Research and Development Authority. "That is probably more true on Long Island than any other portion of the state given how sunny it is, and given how high the price of electricity is, probably only second to the New York City region."
The primary benefit of "going solar" for a homeowner is economic, i.e. reducing their electric bill, Mehta explained. He said this is achieved by two means: one, any solar energy that is generated by the system and consumed by the homeowner goes toward reducing the electricity demand. In addition, any excess electricity generated by the system that isn't consumed by the homeowner goes to the grid and credited to the homeowner on their bill, via net metering, and thus further offsetting their bill to the point of potentially zeroing the bill out.
New York ranks in the top 10 states with the highest electricity rates. The average electricity rate in New York state was 23 cents per kWh in September 2023, leading to an average monthly bill of $145.40. With electricity bills being what they are, Mehta said there are increasing amounts of solar panels being installed every year.
"The technology is getting cheaper and getting proven out," he said. "People are getting more comfortable with it and they see their neighbors have solar and that gives them comfort to go solar."
Mehta noted it takes about seven to 10 years to pay off the installation costs, depending on what part of the state you live, the extent of your individual solar system and overall energy consumption.
Here's a snapshot of the average costs of a solar panel purchase in New York compared to the rest of the country. The table also shows you how much you might be able to save with the 30% federal tax credit. Keep in mind that your total cost could be higher if you add additional equipment, such as a solar battery.

| Typical system size (kW) | Price per watt | Total installed cost | Cost after 30% federal tax credit | |
| New York | 5 | $3.65 | $18,250 | $12,775 |
| National average | 8.6 | $3.67 | $31,558 | $22,091 |

Long Island solar panel incentives and rebates
Between Long Island's relatively large number of sunny days and New York state's solar-friendly policies, shifting to solar energy is certainly worth considering. In fact, CNET named New York state one of the best US states for solar incentives.
Here are the local incentives offered to Long Island residents:
Program | Description |
Federal tax credit | Up to a 30% tax credit that can be applied to federal taxes. The Inflation Reduction Act extended the 30% tax credit for residential systems installed between Dec. 31, 2021 and Jan. 1, 2033. |
State tax credit | New York residents who install a solar system may be eligible for a state tax credit of 25% for some systems of up to $5,000. |
State sales tax exemptions | New York state exempts sales taxes for the sale and installation of many solar-related services. However, the exemption does not include pool heating or other recreational uses. |
Storage incentives | The Long Island Power Authority offers battery storage incentives for both new and existing homeowners. The incentive is available for the energy storage component of a system. |
Net metering program | With net metering in Long Island, you can send your extra solar generation back to the grid in exchange for credits on your electric bill. According to DSIRE, as of February 2023, PSEG/LIPA, the main utility on Long Island, provides the retail rate for each kilowatt-hour of electricity you send to the grid. |
Community solar program | Great for Long Island renters who can't commit to a solar panel purchase, community solar programs allow you access clean energy by subscribing to a solar project. You then save on energy costs with electric bill discounts. You can learn more about how to subscribe to PSEG Long Island community solar options here. |
How to determine which Long Island solar company is best for me
Mehta said residents who choose to go solar need to check references of installation companies. He added you need to talk with people who previously worked with that installer, do some internet research, read reviews and get a request for proposals from at least three separate installers.
"You need to take time and carefully review the proposal including the financing options because the proposal you get may include a loan component or a lease component," Mehta noted.
Installation factors to keep in mind
However, Mehta emphasizes you must do extensive research on whether solar panel installation is appropriate for their home.
"It's completely possible in your particular instance going solar may not make sense," he said. He cites houses that have large amounts of shade or the roof faces south, thus it may not generate solar energy. "You definitely want to take your time before you make that decision."
Some other issues to consider for potential customers may include:
- Roof condition and pitch: The angle and pitch of the house's roof will generate enough solar energy for the panel installation to be a worthwhile investment. "Typically, solar panels perform best on south-facing roofs with a slope between 15 and 40 degrees, though other roofs may be suitable too," according to the US Department of Energy. Homeowners should consult with a reputable solar panel installer to determine the feasibility of installation, leading with conversations regarding size, condition and age of the existing roof.
- Renting vs. owning your home: If you're renting a house and foresee purchasing a home in the not-too-distant future, the costs of installing solar panels may not be worth the investment. A viable alternative may be a community solar program.
- Insurance coverage: Solar panels are susceptible to the weather and other outside forces. You should check your homeowner's insurance policy if there would be coverage for the panels upon completion of installation.
- Homeowners association regulations: New York is one of 21 states that does not have laws prohibiting HOAs from forbidding solar panel installation. You should check your HOA's regulations to see if solar panels are allowed.
How to pay for solar panels in Long Island
Cash: Installing solar panels can be very expensive and many people may not have that much cash available. However, if you can afford one large payment, that eliminates additional interest or fees.
Solar loan: NYSERDA extends three types of loan options including an on-bill recovery loan, a smart energy loan and a renewable energy tax credit bridge loan. "It really depends on your personal situation," Mehta said. "You want to be aware of all the options."
HELOC or home equity loan: Another type of loan possibility is a home equity loan, or HELOC, that allows you to use the equity in your home as collateral. HELOCs can be used for upgrading a house, but your risk losing your home if you cannot repay the loan.
Lease or power purchase agreement: This is an arrangement between the solar panel installation company and the homeowner where the solar company maintains ownership of the system. With a solar lease you rent the panels from a solar company and receive a discounted bill in return. With power purchase agreements, you can earn a discounted rate per kilowatt hour. In both instances, since you do not own panels, you cannot access any tax incentives.
Personal loan: A personal loan through a reputable financial institution may be a solid option by getting the money up front to finance the solar panel installation and then paying back over time along similar lines to a car loan. Most personal loans are unsecured -- meaning it does not require collateral, such as your home. This can eliminate the risk of losing your house if there are unforeseen financial problems. However, personal loans without collateral often have higher interest rates.
