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 Size

The size of the solar system you need to offset your energy usage 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:

  • Reputation: Your solar installer should have a sound reputation as a company and have proven expertise in the field. Two ways to check this are to look for whether a company has technicians certified by the North American Board of Certified Energy Practitioners (NABCEP) and if it has positive reviews from past customers.
  • Solar Panel Brands: Each solar panel brand and type has varying levels of quality, longevity and energy efficiency. They will come at different costs as well. The company you choose plays a role in which solar panel brands you have access to.
  • Installation Process: One of the most important things to understand when adopting solar energy is the installation process itself. Be sure to align on any details you should know with your solar company, such as what permits you should secure and how long the project will take.
  • Contract: When looking through your solar company's contract, ask for clarification about any terms you're not sure of and be sure you understand what happens in scenarios like a system part breaking or the company going out of business.

EcoWatch's West Islip, NY Solar Cost FAQs

How much does it cost to install solar panels in West Islip?

This is a difficult question to answer precisely, because the cost depends on many factors. Generally 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 cost more if you want extra solar equipment or more efficient panels, or if you have higher-than-average energy consumption. Conversely, you can spend less if you go with a smaller solar panel system or less expensive solar panels.

Can you get solar panels for free in West Islip?

You can't get solar panels for free in West Islip. However, you may still be able to afford them on a lower budget. You can lease solar panels for a low upfront cost or, if you'd rather own your solar panels, you can finance them with a solar loan.

Is switching to solar power worth it?

Whether or not solar panels are worth it depends on a variety of factors like how much you pay for electricity and how much direct sunlight your roof gets.

How long do solar panels last in West Islip?

Although the average lifespan of solar panels is 25 to 30 years, that doesn't mean they should be disposed of at that time. What this means is the amount of energy they produce will have decreased significantly after that point. You can decide to replace them once you've had them for that long or you can keep using them at a lower efficiency.
