Factors that Affect Solar Panel Costs in Old Westbury
The cost of installing a solar system in Old Westbury can vary by more than $10,000 from home to home. Your actual cost depends on several factors. The largest one is your system size, and other factors include equipment choices, financing options and the solar company you choose.
Solar Equipment
System size, which is measured in kilowatts, is one of the largest factors that affects the overall cost of installing solar panels. For that reason, it’s important to accurately gauge the size of the solar energy system needed for your home by figuring out your energy needs.The kind of solar equipment you choose can bring your price up or down by thousands or even tens of thousands of dollars. If you choose the most efficient solar panel brands, you’ll end up paying more upfront than if you opted for the most affordable panels. On the other hand, more efficient panels could save you more in the long run on your electric bills. Additionally, extra products, such as solar batteries, can bump up your total well above the Old Westbury average.
Solar Financing Terms
Many homeowners find the average cost of solar in Old Westbury to be prohibitively expensive, even if the investment pays off over time. Fortunately, almost every solar company in the area provides access to financing options. Solar loans greatly decrease upfront costs for most homeowners, but they also result in paying more over time because of interest.You’ll have to consider the long-term cost of loans, including the total interest you’ll pay over the length of the loan. If you’re only able to 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 considerably.
Solar Panel Installation Company
Lastly, the company you hire to install your solar panel system can impact the cost. Old Westbury’s solar companies all have different labor costs and add varying upcharges to equipment. The company’s size sometimes plays the most significant role in the cost of installation. Larger national companies, like SunPro and Sunrun, often have lower prices because of access to greater resources and bulk pricing. Smaller local companies might be more costly, but they can sometimes have better customer service and more customization options, and the occasional sale or promotion can bring their pricing down to compete with bigger companies.

- Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a respected certification organization for clean energy professionals. If your solar panel installer is NABCEP-certified, it most likely has a good reputation and is qualified to do the job well. Another way you can verify your installer’s reputation is by reading reviews.
- Contract: It’s important to read through your solar installer’s contract well to understand what services they will provide, what the warranty covers and what expectations you should have about the project timeline.
- Solar Panel Brands: The brand of solar panel you want plays a role in which company you should opt for, since different companies offer different panels.
- Warranty: Warranties that provide coverage for defective panels and repairs over around 25 years are the best you can get in the business, and offering such a warranty is one sign of a good company.
