How To Choose the Best Solar Company in Central Islip

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

Licensing and Training

New York state does not issue licenses to contractors, so you should check with your county or city government for its specific requirements and regulations. You should also visit a company's website to learn about its private accreditations. Two of the most respected are the Solar Heating Installer and PV Installation Professional certificates, granted by the North American Board of Certified Energy Practitioners (NABCEP). Some companies don't publish this information online, so you should also ask your estimator about them.

Cost of Solar Panels in Central Islip

Your photovoltaic panels' type will impact how much power you can generate. Monocrystalline panels perform the best but cost the most. Polycrystalline panels offer you a budget panel with a traditional design, but at the cost of less power generation. Thin-film panels are excellent for non-traditional roof shapes and cost the least, but don't work well for large residential installations.

If you need to charge an electric vehicle (EV) or use your solar power in dark weather, you can pay extra for add-ons. By choosing the right components, you can make your panel array more efficient and user-friendly. Not every solar provider includes these additional features, so look for a company that sells them if it's important for you.

Generally speaking, it will cost about $18,250 for a five-kilowatt solar array in Central Islip. This table lists more specific pricing information for different solar panel types and system components in your area.

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

Financing Solar Energy in Central Islip

Choosing the right financing solution will affect your overall solar system cost and possible savings. Common payment options include cash payments, leases, loans, and power purchase agreements. We recommend making a cash payment or securing a solar loan for the highest return on investment (ROI). Cash payments require a hefty sum up-front, but you’ll pay the least long-term by avoiding interest. You’ll also have full ownership of your system and can apply for solar incentives to reduce your total costs. Solar loans are another solid option if you don’t want to make a big initial investment. You can pay for your system in installments while still enjoying energy bill savings and solar incentives. However, you’ll spend more in total due to accruing interest. Solar leases allow you to pay a monthly rate to rent your panels, while a power purchase agreement lets you pay a fluctuating rate based on only the energy you use. We generally don't recommend these options since you won't own your system and are disqualified from solar incentives, but they might be suitable in specific circumstances. We recommend working with a provider that offers multiple financing options. Speak with each consultant about what's available, and secure more than one estimate for the best odds of staying within your budget.

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

You are eligible for a 26% federal tax credit for new solar energy devices until the year 2032. Municipal and state governments and utility companies might also offer discounts, rebates, and dedicated financing plans that could save you more.

Solar System Capacity Estimated Payback period
1 kW 2.6 years
2 kW 5.1 years
5 kW 12.9 years
10 kW 25.7 years

How many estimates should I get before making a final solar company decision?

It's smart to obtain at least three different estimates before committing to a single solar provider. This lets you evaluate product quality, pricing, warranty options, and customer feedback. It also helps you gauge a company's reliability, responsiveness and knowledge, all of which are positive signs.
