Factors that Affect Solar Panel Costs in Islip

The cost of installing a solar system in Islip can vary by more than $10,000 from home to home. Your actual cost is dependent on several factors. The largest one is your system size, and other factors include the equipment you choose, financing options and the solar company you choose.

Solar Equipment

When it comes to estimating the price of solar panels 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 consumption, which you can gauge by looking at past electricity bills. Your total cost can increase by about $2,950 for each additional kilowatt you need. Some solar brands — like Maxeon from SunPower — are more expensive upfront but also tend to offer better efficiency. In a city like Islip, where sunlight is relatively abundant, efficiency can quickly pay off. Plus, 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

Many homeowners find the average cost of solar in Islip to be too costly, even if the investment pays off over time. Thankfully, almost every solar company in the area offers financing options. Solar loans substantially decrease upfront costs for most homeowners, but they also result in paying more over time because of interest. Although solar loans make switching to solar energy more accessible for Islip homeowners, they can also add to the total you pay for your system, depending on your interest rate and how long you take to pay off the loan. If you put down a larger down payment, though, you can avoid paying as much in interest.

Solar Panel Installation Company

The solar installer you pick will affect your total cost to make the switch to solar power. Different companies will charge different amounts for the equipment and labor. Additionally, some companies in Islip have more knowledge 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 help you save more money in the long run.

How to Save on Solar Panels

There are numerous companies to choose from in Islip, and some homeowners feel overwhelmed considering their options. Choosing the right company for you can be difficult, so here are some tips to help you decide:

  • Warranty: Companies typically offer different types of warranties that provide different kinds of coverage. A 25-year, all-inclusive warranty is the gold standard.
  • Contract: Look through the contract terms carefully to make sure you understand the overall cost, project timeline rebates and warranties.
  • Solar Panel Brands: Different companies carry various brands and kinds of panels. If you prefer a specific brand, make sure the solar panel installer you're considering has it.
