Factors that Affect Solar Panel Costs in Nassau

Cost is usually one of the most important factors for homeowners who are considering investing in solar. There are a few major factors that affect your total cost in Nassau: solar equipment and system size, financing options and the solar installation company you choose. We'll cover each of these briefly below.

Solar Equipment

One of the most important factors to consider when it comes to the cost of going solar is the size of the solar system, which is measured in kilowatts (kW). The more power your household uses, the larger your system will likely need to be. You can expect to spend around $2,950 per kilowatt in Nassau. The brand and kind of equipment you choose for your solar system can raise or lower the price quite significantly. If you prefer a trusted brand name like Tesla or SunPower, these often have a higher price tag than other brands. Efficiency also matters. Whether you're opting for high efficiency because you have a small roof or just want maximum energy production, you will be looking at a higher equipment cost, but this can typically lead to greater savings over time. Plus, if you want additional equipment like an electric vehicle charger or solar batteries, this will also increase the cost.

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. Thankfully, almost every solar installer in the area provides access to financing options. Solar loans drastically decrease upfront costs for most homeowners, but they also result in a higher cost over time because of interest. When figuring out your overall cost, you should also calculate the interest you'll pay if you choose to go with a solar loan. Also, paying more upfront can reduce the total interest paid over time.

Solar Panel Installation Company

Lastly, the company you opt for to install your solar panels can affect how much it costs. Nassau's solar companies all have different labor costs and add varying upcharges to equipment. Additionally, some companies in Nassau know more about local solar incentives and can help you take advantage of additional rebates or tax exemptions. However, they may charge more for that service. 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 a large number of companies to choose from in Nassau, and some homeowners feel overwhelmed considering their options. Choosing the right company for you can be challenging, so here are some tips to help you decide:

  • Solar Panel Brands: Different companies will carry various brands and models of panels. If you know you want a specific brand, make sure the solar panel installer you're considering has it.
  • Warranty: If you're worried about the longevity of your solar energy system, making sure your installer offers a 25-year, all-inclusive warranty can help put you at ease.
  • Installation Process: Get details from your solar company about the installation process and what to expect, such as when the site survey will be completed and how long it will take.
  • Contract: Even though reading through a contract can be tedious, it's important to do it carefully so you can be sure you understand what services your solar company will provide and how part repairs and replacements will be handled.
