Factors that Affect Solar Panel Costs in West Islip

The cost of installing a solar system in West Islip can vary by more than $10,000 from home to home. Your actual cost is determined by several factors. The most significant one is the size of the system your home needs, and other factors include equipment choices, financing options and the solar installer you choose.

Solar Equipment

The size of the solar system you need to offset your energy usage, 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 about $2,950. There are a lot of different solar panel brands and the one you choose also affects the cost. In many cases, the brands that are more efficient tend to also be more expensive. Additionally, the type of equipment you're looking to get can affect your total cost. If you only need panels, your system will be far less expensive than if you also need solar batteries or an electric vehicle charger.

Solar Financing Terms

Many homeowners find the average cost of solar in West Islip to be too costly, even if the investment pays off over time. Fortunately, almost every solar company in the area provides financing options. Solar loans drastically decrease upfront costs in most cases, but they also lead to a higher cost over time because of interest. 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 finding a solar loan with a low APR could reduce your costs remarkably.

Solar Panel Installation Company

The solar installation company you select will influence your total cost to adopt solar power. Different companies will bill different amounts for the equipment and labor. 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 at a higher cost. It's best to do some research and find a company that provides 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 decide on the right company for you, here are some tips to keep in mind:

  • Installation Process: Get details from your solar company about the installation process and what to expect, such as when the site survey will be done and what the project timeline is.
  • Contract: Before signing a contract with a solar installer, be sure to look it over fully so you understand the terms. Also, ask questions if you're unsure about some of the terms, such as what to do if a component breaks or malfunctions and what services you can expect from them.
  • Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a well-established certification organization for clean energy professionals. If your solar panel installer is NABCEP-certified, it likely has a solid reputation and is qualified to get the job done well. Another way you can check your installer's reputation is by reading reviews.
  • Solar Panel Brands: The type of solar panel you'd like to install plays a role in which installer you should opt for, since different companies have access to different panels.

EcoWatch's West Islip, NY Solar Cost FAQs

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

This is a tough question to answer precisely, because the cost depends on a variety of factors. Broadly 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 be more expensive if you want extra solar equipment or more efficient panels, or if you have above-average energy needs. On the flip side, you can spend less if you want a smaller solar panel system or cheaper solar panels.

What other factors should I consider apart from cost when buying solar panels?

Cost is a very important factor to consider, but whether it's the most important for you depends on your goals for going solar. In cities where rooftop space is limited, efficiency can be more important than the cost. Other factors that are important to take into account are the quality and durability of your solar panels.

Is going solar worth it?

Solar panels can be a good investment for lots of homeowners, but they might not be worth it for everyone. If your home doesn't get enough sunlight and/or your electricity bills are already fairly low, solar panels might not be for you.

What solar power system size is right for my home?

To figure out what solar panel system size you need, you need to know how much energy your home uses and how much sunlight your home gets. For a general estimate, however, since each panel can generally produce about 250 to 400 watt-hours per hour, the average house will need 20 to 35 panels.
