Factors that Affect Solar Panel Costs in Port Jefferson

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

Solar Equipment

The cost of solar panels 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 with better efficiency or power generation use 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 $2,950. The brand and type of equipment you choose for your solar system can raise or lower the price quite significantly. If you prefer a trusted brand name like Tesla or SunPower, these often come at a higher price than other brands. Efficiency also matters. Whether you're opting for high efficiency because you have limited roof space or just want maximum energy production, you will be looking at a higher equipment cost, but this can typically lead to greater savings over time. Plus, if you want additional equipment like an electric vehicle charger or solar batteries, this will also raise the cost.

Solar Financing Terms

If paying for solar panels out of pocket is out of reach, solar loans are an affordable route because they cut back your upfront costs and allow you to pay for your system over a term of, on average, between five and seven years. Although solar loans make adopting solar energy more accessible for Port Jefferson homeowners, they can also raise 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 cut back on how much interest you have to pay.

Solar Panel Installation Company

A final consideration when trying to estimate the cost of solar for your home or business in Port Jefferson is the company you get to install your PV system. As with choosing a company to install new cabinets, for instance, you'll have no shortage of solar installers that offer a range of services for different budgets. Some companies 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 want and also is within your budget.

How to Save on Solar Panels

There are a lot of solar installers to choose from, all of which offer different warranties, solar panel brands and price points. To help you find the right company for you, here are some tips to keep in mind:

  • Contract: Read the contract terms thoroughly to make sure you understand how much it will cost, project completion timeline incentives and warranties.
  • Solar Panel Brands: Not all solar companies have the same brands of solar panels, so the brand and type of panel you want can play a big role in the company you choose.
  • Installation Process: When going solar, it's essential to maintain an open line of communication with your solar company. Confirm that you understand how the installation process works and the project completion timeline.
  • Reputation: Companies that have been in business for many years likely have a high reputation. This is important because it ensures that it will not only see your solar installation through, but will also provide quality aftercare and customer support, such as part repairs and replacements.
