Factors that Affect Solar Panel Costs in Port Jefferson Station

For many Port Jefferson Station homeowners, the decision to go solar comes down to cost. However, the range of solar installation costs can be quite wide in Port Jefferson Station, with typical prices between $20,000 to $40,000. There are various factors that significantly influence the price you’ll pay, which we'll go over below.

Solar Equipment

The size of the solar system you need, which is measured in kilowatts, is the most significant cost factor to consider. For every additional kilowatt you need, you can expect your total to increase by nearly $3,650. The type 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. However, more efficient panels could save you more over time on your energy bills. Additionally, extra products, like solar batteries, can bring your total well above the Port Jefferson Station average.

Solar Financing Terms

Many homeowners find the average cost of solar in Port Jefferson Station to be too costly, even if the investment pays off over time. Thankfully, almost every solar company in the area provides access to financing options. Solar loans substantially decrease upfront costs for most homeowners, but they also result in paying more over time because of interest.However, the interest on solar loans also increases your total costs, so it’s crucial to keep that in mind as well. You can always bring down the total you pay in interest and in some cases even your APR by putting more money down.

Solar Panel Installation Company

Finally, the company you choose to install your solar panels can affect your pricing. Port Jefferson Station’s solar companies all have different labor costs and add varying upcharges to equipment. Companies that only sell products with high efficiency and therefore a higher price point — like Maxeon solar panels from SunPower or Tesla Powerwall batteries — so choosing those installers will generally come with an above-average cost. It’s best to do some research and decide on the company that offers the products, warranties and services you’re looking for and also fit into your budget.
