  • Reviews and feedback from customers: Most Smithtown solar contractors have both favorable and unfavorable reviews. However, a good review ratio shows a company's trustworthiness and responsiveness to issues.

  • Panel quality and brand offerings: The leading solar companies stay up-to-date with new technology, offering equipment from cutting-edge and trustworthy manufacturers.
  • Certifications and credentials: Each installer on our list meets state and city licensing requirements and stays up to date with industry best practices. Many of them have been a part of the Smithtown community for a decade or longer.
  • Warranty and service offerings: Solar installers should stand behind their products and services with warranties. We evaluated how each contractor responds to issues and warranty claims, focusing on timeliness and customer satisfaction.

Benefits of Solar Energy

Solar energy provides multiple advantages that will enhance your home for years to come.

  • Better energy independence: Photovoltaic solar panel systems with battery backups and storage systems work through power outages and emergencies, and you won't have to depend on the power grid for your safety and comfort.
  • Lowered energy bills: You can avoid the premium cost of grid-tied power by generating some electricity at home. Plus, many states provide net metering which can allow you to sell your unused energy back to help pay for your energy bill.
  • Reduced carbon footprint: Solar is the universe's most abundant clean energy source, meaning you can minimize or conquer your home's dependence on non-renewable sources.

How To Choose the Best Solar Company in Smithtown

Choosing a company is the first step toward an effective and cost-efficient solar array. Here are some important factors to bear in mind while shopping for a solar specialist.

Licensing and Training

New York state does not issue licenses to contractors, so you should check with your city or county government for its specific regulations and requirements. Look for private accreditations from the North American Board of Certified Energy Practitioners (NABCEP), among the solar sector's most credible trade groups. Its program includes certifications for both solar photovoltaic and water heating installers.

Cost of Solar Panels in Smithtown

Different solar panel types look and perform differently. Monocrystalline panels offer the best energy production but cost more than other options and generally have the highest quality. Polycrystalline panels provide a lower price point but produce less power. Thin-film panels work well for small projects like RVs and sheds, but they're not ideal for larger installations due to their low performance.

Additional system add-ons, such as battery storage and electric vehicle (EV) chargers, will add to your overall installation costs. However, they might make your solar system more efficient and convenient to use. Not every solar contractor provides these optional components, so look for a contractor that sells them if it's a priority for you.

If you're a resident of Smithtown and are looking into a five-kilowatt solar energy system, you could expect to pay about $18,250 for materials and labor. Find more information on specific component and solar panel costs in the table.

Solar Panel CostAverage Cost
Solar Monocrystalline$1,180
Solar Polycrystalline$920
Thin-Film$538
Solar Battery$755
Solar Home EV Charger$2,832

Financing Solar Energy in Smithtown

Solar contractors use multiple different financing options to lower your costs and increase your savings. Though some providers offer unique payment plans, the most common are solar loans, power purchase agreements (PPAs), cash payments and solar leases. Most solar experts recommend a cash payment or using a solar loan. Cash payments require a large up-front sum, but they help you avoid paying interest, grant you system ownership, and qualify you for cost-saving solar incentives. Solar loans have the same benefits, though you'll pay more in total due to interest and fees. Like a car or home loan, you'll pay a set monthly rate with potentially $0 down. Solar leases involve paying a set monthly rate to use rooftop panels. A PPA (Power Purchase Agreement) enables you to pay a monthly rate based only on the energy you use, similar to an electric bill. We generally don’t recommend these two choices because you won't own the system and cannot use solar incentives. Look for providers that offer several payment plans to find the right fit for your budget.

The table below lists the average payback periods for different capacities of solar systems in Smithtown.

The IRS allows you to claim a 26% federal tax credit for solar panels on the full cost of the solar system, so long as you purchase it before 2032. Local governments and utilities might also offer their own incentives, rebates, and financing programs that could save you more money.

Solar System CapacityEstimated Payback period
1 kW2.6 years
2 kW5.1 years
5 kW12.9 years
10 kW25.7 years
