Factors that Affect Solar Panel Costs in Charleston
The cost of installing a solar system in Charleston can vary by more than $10,000 from home to home. Your actual cost is determined by several factors. The largest one is your system size, and other factors include equipment choices, financing options and the solar installer you choose.
Solar Equipment
The size of the solar energy system you need for your home, which is measured in kilowatts, is the most significant cost factor to consider. For every additional kilowatt you need, you can expect your total to increase by nearly $2,730. The 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, more efficient panels could save you more in the long run on your power bills. In addition, extra products, such as solar batteries, can bring your total well above the Charleston average.
Solar Financing Terms
Most solar companies in Charleston provide solar loans, which reduce your upfront costs of installing a solar system. You'll have to consider the long-term cost of loans, including the amount of interest you'll pay over the length of the loan. If you're only able to get a high-interest loan, then your total can be hundreds or even thousands of dollars above the equipment and labor cost. Making a larger down payment or getting a solar loan with a low APR could reduce your costs considerably.
Solar Panel Installation Company
The solar installer you select will impact your total cost to go solar. Different companies will bill different amounts for the equipment and labor. Larger national companies typically 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 add-on services like electric car charger installation, they might be cheaper overall.

How to Save on Solar Panels
Since the type of solar panels and the installer you choose significantly influences your costs and your system's efficiency, production, and durability, it's important to pick the right ones for you. Here are some things to keep in mind to help with your decision:
- Contract: When looking over your solar company's contract, ask for clarification about any terms you're not sure of and make sure you understand what happens in scenarios such as a system part breaking or the company going out of business.
- Installation Process: Get details from your solar company about the installation process and what to expect, such as when the site survey will be done and how long it will take.
- Warranty: If you're concerned about the longevity of your solar system, verifying that your company offers a 25-year, all-inclusive warranty can help put you at ease.
- Solar Panel Brands: Different companies will have various brands and types of panels. If you want a specific brand, make sure the solar company you're considering has it.
