Factors that Affect Solar Panel Costs in Nassau

Cost is usually one of the most important factors for homeowners considering investing in solar. There are a few primary factors that will push your cost above or below the average in Nassau: solar equipment and system size, financing options and the solar installation company you choose. We'll discuss each of these briefly below.

Solar Equipment

Solar system size, which is measured in kilowatts, is one of the largest factors that affects the overall cost of going solar. Because of that, 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 several different solar panel brands and the one you choose also changes the cost. Generally, the brands that have better efficiency tend to also cost more. Plus, the type of equipment you choose 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

Many homeowners find the average cost of solar in Nassau to be too steep, even if the investment pays off over time. Fortunately, almost every solar installer in the area offers financing options. Solar loans substantially decrease upfront costs in most cases, but they also lead to paying more over time due to interest. It's wise to factor the interest you'll pay in your final cost estimate. If you can afford to put more money down upfront, you can reduce your total costs and how long it'll take to pay off the loan.

Solar Panel Installation Company

A final factor to keep in mind when trying to figure out the cost of solar for your home or business in Nassau is the company you choose to install your solar panel system. Similar to choosing a company to install new cabinets, for example, there are plenty of solar installers that provide a range of services for different budgets. Additionally, some companies in Nassau know more about local solar incentives and can help you learn about 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 help you save more money in the long run.

How to Save on Solar Panels

The solar company you go with will affect not only your overall costs, but also the kinds of solar panel brands, warranties, and other equipment you have access to. When choosing a solar company, there are several important things you should take into account, such as:

  • Solar Panel Brands: The brand of solar panel you need to get plays a part in which installer you should opt for, since different companies have access to different panels.
  • Warranty: A quality company rises above other companies by providing the gold standard warranty — a 25-year, all-inclusive warranty covering parts, labor and performance.
  • Contract: When reading over your solar installer's contract, ask for clarification about any terms you're not sure of and be sure you understand what happens in scenarios such as a system part breaking or if the company goes out of business.
  • Installation Process: An important thing to understand when adopting solar energy is the installation process itself. Be sure to clarify any details you should know with your solar company, such as what permits you should acquire and how long the project will take.
