Factors that Affect Solar Panel Costs in Charleston
Though the average cost of a solar system in Charleston is $12,836, your final cost may differ. There are many factors that can have a sizable impact on the cost of a solar system installation. Below are some of the more important things to consider.
Solar Equipment
The size of the solar panel system you need to offset your energy usage, which is measured in kilowatts, is the most important cost factor to consider. For every additional kilowatt you need, your total will most likely increase by around $2,590. There are several different solar panel brands and the one you choose also changes the cost. In general, the brands that offer higher efficiency tend to also cost more. Additionally, the type of equipment you choose can affect your total cost. If you only need panels, your system will be far less expensive than if you also need solar batteries or an electric vehicle charger.
Solar Financing Terms
Solar panels can save you money on utility bills over time, but they can also be a significant investment. That's why many Charleston homeowners decide to finance their solar panel systems to make paying for solar more affordable. It's a good idea to add the interest you'll pay in your final cost estimate. If you can afford to pay a higher down payment, you can reduce your total costs and how long it'll take to pay back the loan.
Solar Panel Installation Company
The final significant cost factor you should keep in mind is the installer you choose. Given the booming popularity of clean energy solutions in Charleston, you'll have a great number of options to choose from, but each comes at varying price points for labor and equipment. The company's size can sometimes play the most significant role in the cost of installation. Larger national companies, like SunPro and Sunrun, often have lower prices because of access to greater resources and bulk pricing. Smaller local companies might be more costly, but they can sometimes have better customer service and more customization options, and the occasional sale or discount can bring their pricing lower to compete with bigger companies.

How to Save on Solar Panels
The solar panel company you go with will impact not only your total costs, but also the kinds of solar panel brands, warranties, and other equipment you can get. When choosing a solar company, there are a few important things you should keep in mind, including:
- Warranty: An all-inclusive, long-term warranty can help keep your solar panels running smoothly and save you money on repairs and maintenance.
- Reputation: Companies that have been in business for many years likely have a good reputation. This is important because it ensures that it will not only see your solar project through, but will also provide adequate aftercare and customer support, such as part repairs and replacements.
- Contract: It's important to read through your solar installer's contract well to understand what services they will provide, what the warranty covers and what you can expect about your solar system's energy production.
- Solar Panel Brands: Homeowners will have different preferences for panels depending on their locations and energy needs. While there are many options for which brand of solar panel you can get, not every company will have access to the exact one you may want or need, so make sure you peruse their list of offerings before making your decision.

EcoWatch's Charleston, MO Solar Cost FAQs
What is the average cost of installing solar panels in Charleston?
This is a tough question to answer exactly, because the cost depends on many factors. Generally speaking, it costs about $12,950 for a 5-kW system and $25,900 for a 10-kW system after the ITC is applied. It will cost more if you want other solar equipment or higher quality panels, or if you have above-average energy needs. On the flip side, you can spend less if you choose a smaller solar panel system or cheaper solar panels.
Can you get solar panels for free in Charleston?
A solar panel system isn't free in Charleston, but there are some options that can make getting them more viable, such as leasing solar panels or getting a solar loan. There may also be local programs or incentives that can further reduce the cost.
Does Charleston have a net metering program?
Most states offer net metering programs of some kind. Through these, you can be compensated for the extra power your system produces or or receive credits to put toward future electricity bills. Currently there are just three states that don't have any net metering laws: Alabama, Tennessee and South Dakota.
What solar power system size is right for my home?
To figure out how many solar panels you need, you need to know how much energy your home needs and how much sunlight your home gets. For a general estimate, however, since each panel can usually produce about 250 to 400 watt-hours per hour, the average house will need 20 to 35 panels.
