Factors that Affect Solar Panel Costs in Clemson

There are a number of factors that can affect your total installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that installs your solar system.

Solar Equipment

The cost of solar panels varies by thousands of dollars due to a variety of factors. One of the key factors is the system size, which is measured in kilowatts (kW). Solar power systems with higher efficiency or power production use better technology and/or more equipment, both of which can increase costs. For each additional kilowatt you need, your cost can go up by about $2,720. Some solar brands — like Maxeon from SunPower — are more costly upfront but also tend to offer better efficiency. In a city like Clemson, where sunlight is 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 more impactful. Additional equipment like electric vehicle chargers and solar batteries will also increase the cost.

Solar Financing Terms

Many homeowners find the average cost of solar in Clemson to be prohibitively steep, even if the investment pays off over time. Fortunately, almost every solar company in the area offers financing options. Solar loans greatly decrease upfront costs in most cases, but they also result in a higher cost over time due to interest. Even though solar loans make switching to solar energy more accessible for Clemson homeowners, they can also add to the total you pay for your system, depending on your interest rate. If you put down a larger down payment, though, you can cut back on how much interest you have to pay.

Solar Panel Installation Company

The solar installer you select will impact your total cost to make the switch to solar power. Different companies will bill different amounts for the equipment and labor. Larger national companies generally have lower costs, but some local companies undercut them by offering sales and discounts. While the smaller companies might not have specific equipment options like Tesla Powerwall batteries or additional services like electric car charger installation, they might be cheaper overall.

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 some important things you should take into account, such as:

  • Contract: Even though reading through a contract can be tedious, it's important to do it fully so you can make sure you understand what services your solar company will provide and the terms of the warranty.
  • Warranty: Warranties that provide coverage for panel repairs and maintenance over around 25 years are the best you can get in the business, and offering such a warranty is one sign of a quality company.
  • 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 considerable role in the company you go with.
  • Installation Process: Make sure you're on the same page with the company regarding how the installation process will go and what you need to do before your solar panels are installed, such as updating or replacing your electrical system or roof.
