Factors that Affect Solar Panel Costs in East Islip

Though the average cost of a solar system in East Islip is $9,930, your final cost may be above or below the average. There are several factors that can have a major impact on the cost of a solar panel installation. Below are some of the more important things to consider.

Solar Equipment

The cost of solar panel systems varies by thousands of dollars due to a variety of factors. One of the major factors is the system size, which is measured in kilowatts (kW). Solar power systems that have higher efficiency or power production need better technology and/or more equipment, both of which can raise costs. For each additional kilowatt you need, your cost can go up by about $3,650.There are several different solar panel brands and the one you choose also changes the cost. Usually, the brands that are more efficient tend to also cost more. Plus, the type of equipment you’re looking to get can affect your total cost. If you just need panels, your system will be far less expensive than if you also need solar batteries or an electric vehicle charger.

Solar Financing Terms

Solar panels can save you money on energy bills over many years, but they can also be a significant investment. That’s why many East Islip homeowners choose to finance their solar panel systems to make going solar more affordable.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 securing a solar loan with a low interest rate could reduce your costs considerably.

Solar Panel Installation Company

The solar company you opt for to handle your switch to clean energy can play a part in your total costs. There are about 3 solar installation companies operating throughout East Islip, and each can charge varying amounts for labor and equipment.Larger national companies typically have lower costs, but some local companies undercut them by promoting sales and discounts. While the smaller companies might not have specific equipment options like Tesla Powerwall batteries or add-on services like electric car charger installation, they might be cheaper overall.
