Factors that Affect Solar Panel Costs in Islip

For many Islip homeowners, the decision to install solar panels depends on cost. However, the range of solar installation costs can be quite wide in Islip, with typical prices between $20,000 to $40,000. There are a number of factors that significantly influence the price you'll pay, which we'll go over below.

Solar Equipment

When it comes to estimating the price of a solar system in Islip, one of the most important factors is the size of the system you need. Solar systems are sized by kilowatts (kW) and are largely based on your home's energy usage, which you can determine by looking at past electricity bills. Your total cost can increase by about $2,950 for each additional kilowatt you need. The kind of solar equipment you choose can bring your price up or down by thousands or even tens of thousands of dollars. If you opt for the most efficient solar panel brands, you'll end up paying more upfront than if you opted for the most affordable panels. On the other hand, more efficient panels could save you more in the long run on your energy bills. In addition, add-on products, such as solar batteries, can bring your total well above the Islip average.

Solar Financing Terms

If paying for a solar system out of pocket is difficult, solar loans are a solid choice because they decrease your upfront costs and allow you to pay for your system over a term of, on average, between five and seven years. You'll have to consider the long-term cost of loans, including the amount of interest you'll pay over the length of the loan. If you can only get a high-interest loan, then your total can be hundreds or even thousands of dollars above the equipment and labor cost. Making a larger down payment or getting a solar loan with a low APR could reduce your costs significantly.

Solar Panel Installation Company

The final key cost factor you should take into consideration is the installer you choose. Given the booming popularity of sustainable energy solutions in Islip, you'll have many options to choose from, but each comes at different price points for labor and equipment. Additionally, some companies in Islip have more knowledge about local solar incentives and can help you take advantage of additional rebates or tax exemptions. However, 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

Since the type of solar panels and the installer you choose significantly affects your costs and your system's efficiency, production, and durability, it's important to pick the right ones for you. Here are some things to keep in mind to help with your decision:

  • Contract: It's important to read your solar installer's contract well to understand what services they will provide, what the warranty covers and what you can expect about the cost.
  • Warranty: A quality company stands out from other companies by offering the gold standard warranty — a 25-year, all-inclusive warranty covering parts, labor and performance.
  • Reputation: Companies that have been in business 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 adequate aftercare and customer support, such as part repairs and replacements.
  • Solar Panel Brands: Different companies offer various brands and kinds of panels. If you prefer a specific brand, make sure the solar installer you're considering has it.

EcoWatch's Islip, NY Solar Cost FAQs

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

This is a hard question to answer exactly, because the cost depends on a few different factors. Generally speaking, it costs about $14,750 for a 5-kW system and $29,500 for a 10-kW system after the ITC is applied. It will cost more if you want extra solar equipment or higher quality panels, or if you have above-average energy needs. Conversely, you can spend less if you want a smaller solar panel system or less expensive solar panels.

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

Leasing solar panels can be an option if you can't afford to pay upfront or get a solar loan, but since you don't own the system, you can't take advantage of many solar incentives. Also your home value won't increase, so you'll have less savings over time. If you can afford to buy a solar system upfront, then buying is the better option if you want the most financial benefits from going solar.

Can you sell solar power back to the grid in Islip?

Each state has some form of net metering programs except Tennessee, South Dakota and Alabama currently. Some states let you sell power back to the grid, but others just give you credit toward your future energy bills.

How long do solar panels last in Islip?

Though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they stop working completely 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.
