Factors that Affect Solar Panel Costs in Lexington

Although the average cost of solar panels in Lexington is $9,179, your final cost may differ. There are quite a few factors that can have a significant impact on the cost of a residential solar panel installation. Below are some of the more crucial things to take into consideration.

Solar Equipment

The size of the system you need is one of the largest factors that determines the overall cost of going solar. For that reason, it's important to accurately assess the size of the solar energy system needed for your home by figuring out your typical energy use. Some solar panel brands — like Maxeon from SunPower — are more costly upfront but also tend to offer higher efficiency. In a city like Lexington, where sunlight is relatively abundant, efficiency can quickly pay off. Also, if you have a small roof or limited space for your panels, higher efficiency options will be a better option. Additional equipment like electric vehicle chargers and solar batteries will also increase the cost.

Solar Financing Terms

Most solar companies in Lexington offer solar loans, which reduce your upfront costs of installing solar panels. When trying to figure 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 lower the total interest paid over time.

Solar Panel Installation Company

The final significant cost factor you should keep in mind is the installer you choose. Given the booming popularity of green energy solutions in Lexington, you'll have lots of options to choose from, but each comes at different price points for labor and equipment. The size of the company sometimes plays the most significant role in the installation costs. Larger national companies, like SunPro and Sunrun, often have lower prices due to access to more 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 discount can bring their pricing lower to compete with bigger companies.

How to Save on Solar Panels

Since the kind of solar panels and the installation company you choose has an impact on your costs and your system's durability and efficiency, it's important to pick the right ones for you. Here are some tips to keep in mind to help with your decision:

  • Warranty: A quality company stands out from other companies by providing the gold standard warranty — a 25-year, all-inclusive warranty covering parts, labor and performance.
  • Contract: It's important to look over your solar installer's contract fully to understand what services they will provide, what the warranty covers and what you can expect about the installation process.
  • Solar Panel Brands: Not all solar installers have the same brands of solar panels, so the brand and type of panel you want can play a significant role in the company you choose.
  • Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a well-established 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 get the job done well. Another way you can look into your installer's reputation is by reading reviews.
