The average solar panel system costs $2.56/W, including installation costs in South Carolina. For a 5 kW installation, this comes out to about $12,789 before incentives, though prices range from $10,871 to $14,707. After the federal tax credit, the average price drops by 30%.

The cost of solar panels in South Carolina by system size, both before and after the federal investment tax credit (ITC):

These costs do not include the federal ITC or South Carolina state incentives, which will lower this price by at least a few thousand dollars. Your solar panel cost depends on your system’s size. We use cost per watt ($/W) so you can easily compare quotes, controlling for slight variations in system size. 

South Carolina Solar Incentives and Rebates

A concise overview of the best solar incentives and rebates in South Carolina for homeowners considering solar energy:

  1. Solar Energy Tax Credit:
    • South Carolina offers a 25% tax credit on the cost of installing a solar power system. Residents can claim this credit for solar panel installation expenses.
    • The maximum credit is $3,500 or 50% of your state tax liability, whichever is lower.
  2. Utility Incentives:
    • Some utility companies in South Carolina may offer additional incentives or rebates for going solar. Check with your local utility provider for specific details.
    • These incentives can vary, so it’s essential to research and inquire directly with your utility company.
  3. South Carolina Net Metering:
    • Net metering allows homeowners to receive credit for excess solar energy they generate and feed back into the grid.
    • When your solar panels produce more electricity than you use, the excess energy is credited to your account, offsetting future electricity bills.
  4. Federal Solar Tax Credit:
    • While not specific to South Carolina, the federal solar tax credit is a significant incentive for all U.S. homeowners.
    • You can claim a 26% federal tax credit on the total cost of your solar installation.
    • This credit applies to both residential and commercial solar systems.

Consult with local solar installers to make an informed decision about going solar in South Carolina.

Is It Worth Going Solar in South Carolina?

Solar panels are a worthwhile investment for most South Carolina homeowners.

The state ranks 14th in the country for solar conversions. However, residents pay more than the national average for photovoltaic (PV) equipment and below average for energy. To determine if solar is right for your home, consider your monthly energy consumption. Solar panels tend to be profitable if you consume more than 500 kWh of electricity each month. The average electricity consumption in South Carolina is 1,081 kWh, making it viable for many households. A 6 kW residential rooftop solar system costs around $18,000 before incentives, but with federal and state tax credits, the cost can significantly decrease.


How Much Can Solar Panels Save Me in South Carolina?

Finding out how much you can save on solar in South Carolina is not a straightforward answer. It depends on several factors, including the solar billing of your utility company, the size of a potential solar system on your roof, and your household’s energy consumption. While most solar installers will try to cover all your electricity needs, the actual savings will depend on your home’s unique conditions. To get a personal estimate of how much you could potentially save by going solar, fill out a simple form on our website, use Google’s Project Sunroof solar savings calculator, or consult with a couple of local solar installation companies for a personalized savings calculation.

Solar Financing Explained

You can pay for solar panels in a couple of ways:

  • Cash
  • Installer solar loans
  • Personal loans
  • Cash-out refinance or HELOC
  • Solar Leases or Power Purchase Agreements (PPA)

First, there is a cash purchase, which in most cases provides the best price and long-term savings, but the upfront payment is not always what you can afford. If you want to own your solar panels and don’t have about $15,000 to $20,000 in the bank, you’ll have to choose solar panel financing. 

You can consider a personal loan, a home equity line of credit, or a solar loan offered by the solar company. However, keep in mind that these loans come with interest and additional fees. Solar loans often are tied to dealer fees, which can increase the total cost of your solar system by 20% or more in exchange for a lower interest rate. To ensure you get the best possible deal, it is wise to compare the dealer fees and interest rates offered by different installers. This way, you can make an informed decision based on the most favorable terms available. 

Some companies offer solar leases or PPAs that require zero upfront cost. But in such case, you don’t own solar panels and you are not eligible for any solar rebates or the federal tax credit. And, because you have to pay the solar company monthly, your total solar savings will be lower. Ask for detailed savings calculations from a solar installer to decide on the best option. In most cases, you will still be paying less for electricity.

In short, here’s how we pick top installers:

– Companies that handle their own installations instead of outsourcing to subcontractors ensure a higher caliber of work and nurture a culture of excellence and accountability in service.
– Select a company that has a good overall reputation and reviews on sites like SolarReviews, BBB, Google Maps, and Yelp.
– The company is licensed, insured, and holds relevant certifications such as NABCEP certification.

What to Look for In a Solar Company

To ensure that you partner with a great provider that can meet your needs of going solar, look for the following:
– Make sure the solar installer has industry-standard certifications, such as those from the North American Board of Certified Energy Practitioners (NABCEP), indicating that they meet the gold standard in renewable energy installations. Also, verify if they are licensed, bonded, and insured for residential solar projects in your area. If subcontractors are involved, check their credentials as well.
– Prioritize installers with a proven track record in solar installations, ideally with at least 5+ years of experience. Ask about the number of systems they’ve installed and their project portfolio. A competent installer should openly discuss the solar panels, inverters, and batteries they use if they help to take advantage of local solar incentives and rebates, and warranty coverage specifics.
– Your installer should be forthcoming about the installation process and answer any questions you might have, like “How many solar panels will I need? Why?”, “Can you give me a detailed cost breakdown based on my energy consumption?”, “What solar panel brands do you install? Why?”, etc.. They should also be transparent about their use of subcontractors, detailing their roles and how their work will be supervised.
– A preliminary evaluation of your roof’s condition is the groundwork. The installer should advise on necessary repairs to ensure it’s ready for solar panel installation and clarify responsibilities for any potential roof damage during the process. Discuss aesthetic concerns, such as the placement of solar panels around roof vents or the possibility of relocating vents for a more visually appealing setup.
– Check the installer’s reputation through online reviews and testimonials. They should be able to connect you with past customers willing to share their experiences. Personal recommendations from friends or neighbors who’ve gone solar can also be invaluable.
– Solar installation costs can vary widely, so obtaining multiple quotes is advisable. Experienced installers will adjust their offers to your home’s specifics—size, energy needs, etc. For an objective cost comparison, calculate the price per watt of the proposed system, giving you a standardized basis to evaluate different quotes.

Should You Choose a Local Solar Installer or a Big National Company?

Always choose a local solar company over a big national corporation. Small local companies that operate in a distinct local area are better than multi-state and national solar companies and large corporations. It’s the small local companies who get the best reviews on our website, and it’s the national multistate companies who get very poor reviews. Why so, you may ask? 
Solar is a local service business, for the most part, and it is extremely difficult to run a solar company and offer good customer service to many locations from a central office. 
Local ones have a community connection, they know better the incentives and regulations in the area, and they simply care more about you than large businesses trying to get into your pocket and overprice you. While multi-state solar companies might try to convince you by financial stability and “quality of installations across different locations”, try to choose a local company that meets all your criteria.

What Does a Solar Installation Look Like?

Here’s how a solar system installation will look like once the design for your solar system is approved:
– First, a solar installer should estimate your energy needs, and analyze your annual and monthly electricity consumption, which you can find on utility bills measured in kilowatt-hours (kWh). Such calculations will help to understand potential savings, payback period, and the system size you need.
– A home energy audit is something every experienced solar company would do to understand the size and output needed.
– Next question on the list: are your house’s roof conditions good enough for installation? A solar installer should carefully inspect the roof and ensure its conditions and orientation are good to go, how and where to better place solar panels and wire the system.
– Next, they will design the system and show you how it’s going to look. 
You will usually need a permit to install solar panels from your local authorities, and the solar provider should handle all the paperwork.
– The entire process might take up to 3 months depending on the state and local regulations, while the system installation is usually up to 3 days (might take longer depending on roof conditions and system complexity).
– The installation crew should always clean up and remove any debris, leaving your house in good condition.
– When the system is installed, it should be checked and approved by local municipality inspection. 
– If you’re connecting your system to the grid, it has to be wired to your local utility system. You’ll apply for connection through your utility company, which will also want to inspect your system to ensure it’s following utility guidelines. Some installers may help you with this step, so always ask. Once you have all the permits, your system will be up and running, powering your home with solar.
