Factors that Affect Solar Panel Costs in Lexington

For many Lexington homeowners, the decision to adopt solar energy depends on cost. However, the range of solar installation costs can be quite wide in Lexington, with typical prices between $20,000 to $40,000. There are numerous factors that considerably influence the price you'll pay, which we'll go over below.

Solar Equipment

When it comes to estimating the price of a solar panel system in Lexington, one of the most crucial factors is the size of the system you need. Solar systems are sized by kilowatts (kW) and are chiefly based on your home's energy consumption, which you can figure out by looking at past power bills. Your overall cost can increase by around $2,940 for each additional kilowatt you need. The type of solar panels and equipment you want is another factor that will considerably impact costs. Solar panels that are more efficient, like monocrystalline panels, tend to come at a higher price. Furthermore, solar equipment consists of more than just the solar panels themselves. You'll also need to think about the kind of racks used to mount the panels, inverters, solar batteries, etc. It's important to take all of this into consideration when looking into a solar system that's in your budget.

Solar Financing Terms

Solar panels can save you money on utility bills over time, but they can also be a big investment. That's why many Lexington homeowners decide to finance their solar panel systems to make paying for solar more affordable. However, the interest on solar loans also increases your overall costs, so it's important to consider that as well. You can always bring down the total you pay in interest and possibly even your APR by putting more money down.

Solar Panel Installation Company

The solar panel installation company you pick will affect your total cost to adopt solar energy. Different companies will charge different amounts for the equipment and labor. The company's size can sometimes play the most significant role in the cost. Larger national companies, like SunPro and Sunrun, often have lower prices due to greater resources and better pricing. Smaller local companies might be more costly, but they generally have better customer service and more customization options, and the occasional sale or promotion can bring their pricing down to compete with bigger names.

How to Save on Solar Panels

The solar installer you choose will influence 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 some important things you should take into account, such as:

  • Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a respected certification organization for renewable 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 check your installer's reputation is by reading reviews.
  • Solar Panel Brands: Homeowners will have different preferences for panels depending on their locations and energy needs. Although 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 be sure to take a look at their list of options before deciding.
  • Warranty: If you care about the endurance of your solar system, making sure your installer offers a 25-year, all-inclusive warranty can help put you at ease.
  • Contract: Although reading through a contract can be tedious, it's important to do it thoroughly so you can make sure you understand how much the equipment and services will cost and the terms of the warranty.
