Factors that Affect Solar Panel Costs in East Islip

There are many factors that can play into your solar panel installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that does the installation.

Solar Equipment

The size of the solar energy system you need for your household, which is measured in kilowatts, is the most significant cost factor to consider. For every additional kilowatt you need, your total will most likely increase by about $2,950. Some solar panel brands — like Maxeon from SunPower — are more costly upfront but also tend to offer higher efficiency. In a city like East Islip, where sunlight is relatively abundant, efficiency can quickly pay off. In addition, if you have a small roof or you don't have a lot of space for your panels, higher efficiency options will be a better option. Additional equipment like electric vehicle chargers and solar batteries will also increase the cost.

Solar Financing Terms

For some homeowners, paying for a solar system out of pocket can be difficult. Solar loans are offered by most installers in East Islip, which can bring down, or in some cases totally eliminate, your upfront costs to make solar more accessible. However, the interest on solar loans also adds to your total costs, so it's vital to take that into consideration as well. You can always lower the total you pay in interest and in some cases even your APR by making a larger down payment.

Solar Panel Installation Company

The solar panel installer you choose will affect your total cost to go solar. Different companies will bill different amounts for the equipment and labor. You may see national solar installers that have lower prices due to their bigger brand name and access to bulk equipment pricing, or you might see small, local installation companies offering deals or specials to compete with those major players.

How to Save on Solar Panels

There are a large number of companies to choose from in East Islip, and some homeowners feel overwhelmed considering their options. Selecting the right company for you can be challenging, so here are some tips to help you decide:

  • Contract: When reading over your solar company's contract, ask questions about any terms you're not sure of and be sure you understand what happens in scenarios like a system component breaking or the company going out of business.
  • Solar Panel Brands: Homeowners will have different preferences for panels depending on their locations and how much efficiency they need. Although there are many options for which kind of solar panel you can get, not every company will have access to the exact one you may want or need, so make sure you take a look at their list of offerings before deciding.
  • Reputation: Companies that have been operating for many years likely have a solid reputation. This is important because it ensures that it will not only see your solar project through, but will also provide quality aftercare and customer service, such as part repairs and replacements.
  • Warranty: If you care about the durability of your solar panels, making sure your installer offers a 25-year, all-inclusive warranty can give you some peace of mind.

EcoWatch's East Islip, NY Solar Cost FAQs

What is the average cost of installing solar panels in East Islip?

The average cost of solar panels in East Islip is about $14,750 for a 5-kW system and $29,500 for a 10-kW system before the ITC, but the real cost will depend on stuff like the kind of solar panels you want, what size system you need and how much energy you consume.

Is it better to lease or buy solar panels in East Islip?

Leasing solar panels can be an appealing choice, as it usually comes with low or $0 upfront payments. The drawback is that you won't be able to save as much. If you lease, you don't own the system, so you can't claim any tax rebates and credits and your home value won't increase. Buying solar panels is a better way to go if you want to get the most savings.

Do solar panels increase your property value?

Solar panels can increase the value of your home remarkably as long as you buy or finance your panels and don't opt for a solar lease or power purchase agreement (PPA). According to research done by Zillow, the average home value increases by about 4.1% after installing a solar system."

How long do solar panels last in East Islip?

On average, the lifespan of solar panels is about 25 to 30 years. Some even last up to 50 years, but their efficiency goes down by about 0.8% each year. You can choose to replace them sooner if you want to maintain a larger level of energy production.
