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 is determined by several factors. The most significant one is the size of the system your household needs, and other factors include equipment choices, financing options and the solar installer you choose.

Solar Equipment

The cost of solar panels varies by thousands of dollars due to some different factors. One of the major factors is the system size, which is measured in kilowatts (kW). Solar power systems with better efficiency or power generation need better technology and/or more equipment, both of which can raise costs. For each additional kilowatt you need, your cost can go up by about $2,950. The type of solar equipment you choose can bring your price up or down by thousands or even tens of thousands of dollars. If you opt for 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, higher efficiency could save you more in the long run on your energy bills. Additionally, add-on products, like 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 steep, even if the investment pays off over time. Thankfully, almost every solar installer in the area offers financing options. Solar loans greatly decrease upfront costs in most cases, but they also result in paying more over time because of interest. However, the interest on solar loans also increases your total costs, so it's vital to include that in your estimate as well. You can always lower the total you pay in interest and sometimes even your APR by putting more money down.

Solar Panel Installation Company

A final consideration when trying to figure out the cost of solar for your home or business in Old Westbury is the company you get to install your solar system. Similar to choosing a company to build a deck or pool, for instance, there's no shortage of solar installers that offer a range of services at different costs. Additionally, some companies in Old Westbury have more knowledge about local solar incentives and can help you make good use of additional rebates or tax exemptions. However, they may charge more for walking you through the whole process. Even if they cost more upfront, they could end up saving you more money in the long run.

How to Save on Solar Panels

There are many companies to choose from in Old Westbury, and some homeowners feel overwhelmed considering their options. Choosing the right company for you can be difficult, so here are some tips to help you decide:

  • Warranty: A comprehensive, long-term warranty can help keep your solar system running smoothly and save you money on repairs and maintenance.
  • Solar Panel Brands: Homeowners will have different preferences for panels depending on their roof configurations and energy needs. Even though there are many options for which type of solar panel you can get, not every company will have the exact one you may want or need, so make sure you ask for their list of options before making your decision.
  • 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 the warranty covers and if there are any guarantees about energy production.
  • Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a respected certification organization for sustainable energy professionals. If your solar panel installer is NABCEP-certified, it likely has a good reputation and is qualified to install your solar system. Another way you can check your installer's reputation is by reading reviews.

EcoWatch's Old Westbury, NY Solar Cost FAQs

What is the average cost of installing solar panels in Old Westbury?

This is a difficult question to answer exactly, because the cost depends on a variety of 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 usage. On the flip side, you can spend less if you go with a smaller solar panel system or less efficient solar panels.

What other factors should I consider in addition to 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 think about are the quality and durability of your solar panels.

Is it worth going solar in Old Westbury?

Solar panels can be a great 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 pretty low, solar panels might not be for you.

How often do you have to replace solar panels?

On average, the lifespan of solar panels is about 25 to 30 years. Some even last up to 50 years, but their efficiency decreases by about 0.8% each year. You can choose to replace them sooner if you want to maintain a larger level of energy production.
