Factors that Affect Solar Panel Costs in Central Islip

There are a number of criteria that can influence your installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that installs your solar panels.

Solar Equipment Size

The cost of solar panel systems varies by thousands of dollars due to a few different factors. One of the key factors is the system size. Solar power systems with better efficiency or power production use better technology and/or more equipment, both of which can increase costs. For each additional kilowatt you need, your cost can go up by about $2,950. There are a lot of different solar panel brands and the one you choose also changes the cost. Generally, the brands that offer higher efficiency tend to also be more expensive. Additionally, the type of equipment you're looking to install can affect your total cost. If you just need panels, your system will be much less expensive than if you also need solar batteries or an electric vehicle charger.

Solar Financing Terms

Most solar companies in Central Islip provide solar loans, which reduce your upfront costs of installing solar. However, the interest on solar loans also adds to your total costs, so it's crucial to consider that as well. You can always lower the total you pay in interest and possibly even your APR by making a larger down payment.

Solar Panel Installation Company

The solar company you opt for to handle your switch to clean energy can have an effect on your total costs. There are about 3 solar installation companies operating throughout Central Islip, and each can charge varying amounts for labor and equipment. Companies that only sell high-quality, high-efficiency and high-price products — 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 go with the company that has the products, warranties and services you're looking for and also is within your budget.

How to Save on Solar Panels

There are a large number of companies to choose from in Central Islip, and some homeowners feel overwhelmed considering their options. Selecting the right company for you can be difficult, so here are some tips to help you decide:

  • Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a well-established certification organization for renewable energy professionals. If your solar panel installer is NABCEP-certified, it likely have a solid reputation and are qualified to do the job well. Another way you can check your installer's reputation is by reading reviews.
  • Solar Panel Brands: Homeowners will have different preferences for panels depending on their roof configurations and how much efficiency they need. Although there are many options for which model of solar panel you can get, not every company will have access to the exact one you may want or need, so make sure you take a look at their list of options before making your decision.
  • Contract: Read the contract terms closely to make sure you understand the cost breakdown, project completion timeline incentives and warranties.
  • Installation Process: Make sure you're on the same page with the installer in regard to how the installation process will go and what you need to do before your solar panels are installed, such as updating or replacing your electrical system or roof.

EcoWatch's Central Islip, NY Solar Cost FAQs

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

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 additional solar equipment or more efficient panels, or if you have higher-than-average energy usage. Conversely, you can spend less if you choose a smaller solar panel system or less expensive solar panels.

Is cost the most important thing to think about when buying solar panels?

The upfront cost is a crucial factor to consider, but whether it's the most important for you depends on why you decided to go solar. In areas where rooftop space is limited, efficiency can be more important than the cost. Other factors that are important to consider are the quality and durability of your solar panels.

Is it worth going solar in Central Islip?

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

What solar power system size is right for my home?

The exact number of solar panels you need depends on your household energy consumption and the amount of sunlight your roof gets. You can take a look at your energy bills for the past year to get an idea of the solar system size you'll need.
