Benefits of Solar Energy

Solar energy offers multiple advantages. Here are some highlights.

  • Better energy independence: Photovoltaic systems with battery storage operate through blackouts and emergencies, and you won't have to depend on the power grid for your safety and comfort.
  • Reduced carbon footprint: Using clean solar power means you're less dependent on fossil fuels, which emit harmful greenhouse gasses.
  • Lowered energy bills: Solar panels let you generate your own energy to power your home, reducing your periodic electricity costs. You can eliminate your bills completely if you go off-grid.

How To Choose the Best Solar Company in Islip

The purchase price and effectiveness of solar panels often rely on which company installed them. Consider each of these elements in your company search.

Licensing and Training

New York regulators do not issue licenses to contractors, so you should check with your county or city 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 respected trade groups. Its program includes certifications for both solar photovoltaic and water heating installers.

Cost of Solar Panels in Islip

The style of solar panels you choose determines how much electricity you can produce. Monocrystalline panels give you the best performance but cost more upfront. Polycrystalline panels produce less power, but they're worth it if you want a traditional panel style without the high cost. Thin-film panels aren't recommended for large residential installations, but they are ideal for small projects like converting RVs and sheds.

You can also add battery backups and electric vehicle (EV) chargers. These will increase your total project price, but they can boost your solar system's performance. Not every solar contractor provides these optional components, so look for a contractor that sells them if it's a priority for you.

Most Islip homeowners opt for solar systems sized for five kilowatts (kW) of electrical capacity. These systems cost about $18,250 to set up, considering both materials and labor. You can find more specific cost information in the table.

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 Islip

Solar installers use multiple different financing options to lower your costs and increase your savings. Though some providers offer unique payment plans, the most common are power purchase agreements (PPAs), solar loans, solar leases and cash payments. Though it requires a large up-front payment, cash is the most economical choice because it doesn't accrue interest and qualifies you for incentives. Solar loans are the second most effective option. As with a home or auto loan, you'll pay a monthly rate towards system ownership, including interest. You can still apply for valuable solar incentives, and depending on your lender, you could put as little as $0 down. Solar leases involve paying a set monthly rate to use rooftop panels. A PPA (Power Purchase Agreement) lets you pay a monthly rate determined by the energy you use, similar to an electric bill. We generally don’t recommend these two options because you won't own the system and are disqualified from using solar incentives. We suggest working with a provider that offers multiple financing options. Talk to each salesperson about what's available, and get more than one estimate for the best odds of staying within your financial plan.

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

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

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

Frequently Asked Questions About Solar in Islip

How much energy and money could I save per year by switching to solar?

Most Islip homeowners spend about $1,525 on energy each year. Your costs could drop by $1,151.18 for each kilowatt you generate after you pay off a solar array.

Is solar energy readily available in Islip?

Yes, solar energy is on the rise in Islip. Some homes already generate solar power on-site or through utility grids, and they're fortified by a state solar economy with 10740 job opportunities and counting.

Will solar panels raise my Islip home worth?

Yes, solar panels will boost your property value. According to the National Renewable Energy Laboratory, for every dollar you reduce on energy bills, your home value rises by $20. So, if your panels save you $600 per year on energy costs, your property could appreciate $12,000.

What if I live in a heavily-wooded or rainy

Even if your property has high tree cover, you could still use solar energy. Your installer will optimize your system's performance by selecting the proper site for panels, positioning them to capture the most sunlight throughout the year, cleaning them regularly, and installing a battery backup system. This way, you can store solar power and utilize it as necessary.

How can I assess my property's solar suitability?

To determine your home's solar readiness, there's no substitute for a comprehensive estimate from a local solar provider. However, you can use the PVWatts tool for a simple solar viability prediction based on public data, including local weather and topography, panel efficiency, system size, and tree cover.

How long will an average solar system last?

Modern solar panels are designed for durability. The average panel is good for 25 years of service. Budget panels tend to last shorter than higher-quality models.

How does "net metering" work, and do I need to participate?

Most states and utilities run net metering programs, and some mandate homeowners to join. Once you register, you can obtain a bill credit or check for any surplus electricity you produce and send to the grid. Generally, power companies reimburse solar homeowners at a wholesale or "avoided-cost" rate.

What's the difference between a PPA and a solar lease?

Choosing a leasing option means your solar company will handle panel maintenance while you make fixed monthly payments. PPAs differ slightly because you pay for just the electricity you produce.

You don't own the panels with either option, though you can choose to "buy out" of the contract for a fee.
