Factors that Affect Solar Panel Costs in East Islip

For many East Islip homeowners, the decision to install a solar energy system comes down to cost. However, the range of solar installation costs can be quite wide in East Islip, with typical prices between $20,000 to $40,000. There are numerous factors that considerably influence the price you'll pay, which we'll go over below.

Solar Equipment Size

The cost of solar panel systems varies by thousands of dollars due to some different factors. One of the key factors is the system size. Solar power systems with greater efficiency or power generation need better technology and/or more equipment, both of which can increase costs. For each additional kilowatt you need, your cost can go up by about $2,950. Some solar brands — like Maxeon from SunPower — cost more upfront but also tend to offer higher efficiency. In a city like East Islip, where sunlight is relatively abundant, efficiency can quickly pay off. Also, if you have a small roof or limited 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

If paying for solar panels out of pocket is too expensive, solar loans are a popular route because they decrease your upfront costs and allow you to pay for your system over five to seven years on average. When considering your overall cost, you should also calculate the interest you'll pay if you opt for a solar loan. Also, paying a higher down payment can reduce the total interest paid over time.

Solar Panel Installation Company

The solar company you opt for to handle your switch to green energy can have an effect on your total costs. There are about 3 solar installation companies in East Islip, and each can charge different amounts for labor and equipment. Additionally, some companies in East Islip are more knowledgeable about local solar incentives and can help you take advantage of additional rebates or tax exemptions. Though, they may charge more for walking you through the whole process. Even if they cost more upfront, they could end up saving you more money in the long run.

How to Save on Solar Panels

The solar panel company you opt for will impact not only your overall costs, but also the types of solar panel brands, warranties, and other equipment you have access to. When choosing a solar company, there are a few important things you should consider, including:

  • Warranty: A comprehensive, long-term warranty can help keep your solar panels running for a long time and save you money on part replacement and repairs.
  • Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a well-established certification organization for renewable energy professionals. If your solar panel installer is NABCEP-certified, it likely has a good reputation and is qualified to do the job well. Another way you can check your installer's reputation is by reading reviews.
  • Contract: Review the contract terms carefully to make sure you understand the cost breakdown, project timeline incentives and warranties.
  • Solar Panel Brands: Homeowners will have different preferences for panels depending on their locations and energy needs. While there are many options for which model of solar panel you can get, not every company will have the exact one you may want or need, so make sure you take a look at their list of offerings before making your decision.

EcoWatch's East Islip, NY Solar Cost FAQs

How much does it cost to install 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 things such as the kind of solar panels you want, what size system you need and how much energy you use.

What other factors should I consider in addition to cost when buying solar panels?

Cost is a crucial factor to consider, but whether it's the most important for you depends on your reasons for going solar. In areas where rooftop space is limited, efficiency can be more important than the cost. Other factors that are important to be mindful of are the quality and durability of your solar panels.

Can solar panels completely eradicate my energy bills?

It is possible to eliminate your electricity bills with solar panels, but for most homeowners throughout East Islip, that will require at least a 10-kW system. Not all homes will have the roof space for that size system, so you'll want to check with a local solar installer to see how many panels can fit on your roof.

How often do you have to replace solar panels?

Though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they are completely unusable at that time. What this means is how much energy they produce will have decreased significantly after that point. You can choose to replace them once you've had them for that long or you can keep using them at a lower efficiency.
