Factors that Affect Solar Panel Costs in Lexington

The cost of installing a solar system in Lexington can vary by more than $10,000 from home to home. Your actual cost is dependent on several factors. The largest one is your system size, and other factors include the equipment you choose, financing options and the solar company you choose.

Solar Equipment

Solar system size, which is measured in kilowatts, is one of the largest factors that influences the overall cost of going solar. For that reason, it's a priority to accurately gauge the size of the solar energy system needed for your home by figuring out your average energy use. 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. However, higher efficiency could save you more in the long run on your energy bills. Additionally, extra products, such as solar batteries, can bring your total well above the Lexington average.

Solar Financing Terms

For some homeowners, paying for solar panels out of pocket can be financially overwhelming. Solar loans are available from most installers in Lexington, which can reduce, or in some cases completely eliminate, your upfront costs to make solar more affordable. It's wise to factor the interest you'll pay in your final cost estimate. If you can afford to pay a larger down payment, you can reduce your total costs and how long it'll take to pay back the loan.

Solar Panel Installation Company

The solar company you select will play a role in your total cost to go solar. Different companies will charge different amounts for the equipment and labor. You may see national solar installers that have lower prices due to their larger brand name and access to bulk equipment prices, or you might see small, local installation companies offering deals or specials to compete with those major players.

How to Save on Solar Panels

The solar company you choose will influence not only your total costs, but also the kinds of solar panel brands, warranties, and other equipment you have access to. When choosing a solar company, there are a few important things you should consider, such as:

  • Reputation: Your solar installer should have a sound reputation as a company and have demonstrated expertise in the field. Two ways to check this are to look for whether a company has technicians that hold a certification from the North American Board of Certified Energy Practitioners (NABCEP) and if it has good reviews from past customers.
  • Contract: Before signing a contract with a solar installer, make sure you look it over carefully so you understand the terms. Also, ask questions if you're not certain about some of the terms, such as what the warranty covers and if there are any guarantees about energy production.
  • Warranty: An all-inclusive, 25-year warranty can help keep your solar panels running for a long time and save you money on repairs and maintenance.
  • Solar Panel Brands: Each solar panel brand and kind offers varying levels of quality, durability and energy efficiency. They will come at different prices as well. The company you choose plays a role in which solar panel brands you have access to.
