Factors that Affect Solar Panel Costs in Greenville

For many Greenville homeowners, the decision to install a solar energy system comes down to cost. However, the range of solar installation costs can be quite wide in Greenville, with typical prices between $20,000 to $40,000. There are a few factors that greatly influence the price you’ll pay, which we'll go over below.

Solar Equipment

System size, which is measured in kilowatts, is one of the largest factors that affects the overall cost of going solar. For that reason, it’s a priority to accurately ascertain the size of the solar energy system needed for your home by figuring out your average energy use.Some solar panel brands — like Maxeon from SunPower — cost more upfront but also tend to offer better efficiency. In a city like Greenville, where sunlight is relatively abundant, efficiency can quickly pay off. In addition, 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

Solar panels can save you money on utility bills over many years, but they can also be a significant investment. That’s why many Greenville homeowners choose to finance their solar panel systems to make paying for solar more affordable.However, the interest on solar loans also adds to your all-in costs, so it’s vital to take that into consideration as well. You can always reduce the total you pay in interest and in some cases even your APR by putting more money down.

Solar Panel Installation Company

The solar installer you choose will affect your total cost to go solar. Different companies will bill different amounts for the equipment and labor.Some companies only sell high-quality, high-efficiency and high-price products — like Maxeon solar panels from SunPower or Tesla Powerwall batteries — so choosing those installers will generally cost more. It’s best to do some research and decide on the company that offers the products, warranties and services you’re looking for and also fit into your budget.

How to Save on Solar Panels

The company that does your solar system installation will affect the warranties and brands you have access to, and it will also have an impact on your total cost. Because picking a company can be a challenge, we have some tips to help you, such as:

  • Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a respected certification organization for clean energy professionals. If your solar panel installer is NABCEP-certified, it most likely has a solid reputation and is qualified to install your solar system. Another way you can research your installer’s reputation is by reading reviews.
  • Warranty: Warranties that provide coverage for defective panels and repairs over a couple decades are the best you can get in the business, and offering such a warranty is one indication of a good company.
  • Solar Panel Brands: Each solar panel brand and type offers varying levels of quality, longevity and efficiency. They will come at different costs as well. The company you choose plays a role in which solar panel brands you have access to.
  • Installation Process: Make sure you’re on the same page with the company in regard to how the installation process will go and what you need to do before your solar panels are installed, such as updating your electrical system or roof.
