Factors that Affect Solar Panel Costs in Stony Brook University
The cost of installing a solar system in Stony Brook University can vary by more than $10,000 from home to home. Your actual cost is dependent on several factors. The most significant one is the size of the system your household needs, and other factors include the equipment you choose, financing options and the solar company you choose.
Solar Equipment
Solar system size, which is measured in kilowatts, is one of the largest factors that determines the overall cost of going solar. That’s why it’s crucial to accurately ascertain the size of the solar energy system needed for your home by figuring out your typical energy use.There are a lot of different solar panel brands and the one you choose also affects the cost. Generally speaking, the brands that have better efficiency tend to also cost more. Additionally, the type of equipment you’re looking to install can affect your total cost. If you just need panels, your system will be far less expensive than if you also need solar batteries or an electric vehicle charger.
Solar Financing Terms
For some homeowners, paying for solar out of pocket can be difficult. Solar loans are provided by most installers in Stony Brook University, which can lower, or in some cases eliminate, your upfront costs to make solar more affordable.You’ll have to consider the long-term cost of financing options, 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 more than the principal cost. Making a larger down payment or finding a solar loan with a low APR could reduce your costs remarkably.
Solar Panel Installation Company
Lastly, the company you hire to install your solar system can impact the cost. Stony Brook University’s solar companies all have different labor costs and add varying upcharges to equipment. Some companies 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 with an above-average cost. It’s best to do some research and find a company that offers the products, warranties and services you’re looking for and also fit into your budget.

How to Save on Solar Panels
There are many solar installers to choose from, all of which offer different warranties, solar panel models and price points. To help you select the right company for you, here are some tips to keep in mind:
- Installation Process: When making the switch to solar energy, it’s essential to keep an open line of communication with your solar installer. See to it that you understand how the installation process will go and the project completion timeline.
- Warranty: A high-quality company stands out from other companies by providing the gold standard warranty — a 25-year, all-inclusive warranty covering parts, labor and performance.
- Reputation: Your solar installer should have a good reputation as a company and have verifiable expertise in the field. A couple of ways to check this are to look for whether a company has technicians that hold a certification from the North American Board of Certified Energy Practitioners (NABCEP) and if it has good reviews from past customers.
- Contract: Even though reading through a contract can take a lot of time, it’s important to do it carefully so you can make sure you understand how much the equipment and services will cost and the terms of the warranty.
EcoWatch's Stony Brook University, NY Solar Cost FAQs
What is the average cost of installing solar panels in Stony Brook University?
The average cost of solar panels in Stony Brook University is about $18,250 for a 5-kW system and $36,500 for a 10-kW system before the ITC, but the actual cost will depend on things such as the type of solar panels you want, what size system you need and how much energy you consume.
Is it better to lease or buy solar panels in Stony Brook University?
Leasing solar panels can be an option if you can’t pay upfront or get a solar loan, but since you don’t own the system, you don’t have access to many solar incentives. Also your property value won’t increase, so you’ll have less savings over time. If you can afford to buy a solar system upfront, then buying is the better option if you want the most bang for your buck from going solar.
How much can I save on electricity bills after switching to solar?
It is possible to eradicate your electricity bills with solar panels, but for most homeowners throughout Stony Brook University, that will require at least a 10-kW system. Not all homes will have the roof space for that size system, so you’ll want to contact a local solar installer to see how many panels can fit on your roof.
How long do solar panels last in Stony Brook University?
Even though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they stop working completely at that time. What this means is their energy production will have decreased significantly after that point. You can replace them after having them for that long or you can keep using them at a lower efficiency.
