Summary of South Carolina solar incentives 2021
Palmetto State lawmakers passed a monumental solar bill in 2019, which lifted the state’s net metering cap and protected the right of homeowners to generate and sell their own electricity! Read on to find out how much you can save with solar in 2021.
There are great incentives for going solar in South Carolina, including both state and federal tax credits, which combined can save you up to half the cost of installing solar panels.
On this page, you can:
-
Learn what solar incentives are available to South Carolina homeowners
-
See what South Carolina solar incentives you qualify for based on your utility company and city
-
Find out how much these incentives and/or South Carolina solar tax credits will reduce your cost to go solar and add batteries
Federal solar investment tax credit
The federal solar investment tax credit will have the biggest impact on the cost you will face to go solar in South Carolina
This perk is commonly known as the ITC, short for “Investment Tax Credit”. If you install your photovoltaic system in 2020, the federal tax credit is 26% of the cost of your solar panel system. This is 26% off the entire cost of the system including equipment, labor and permitting.
Example: If your solar energy system costs $20,000, your federal solar tax credit would be $20,000 x 26% = $5,200.
The federal tax credit falls to 22% at the end of 2022.
Net energy metering in South Carolina
With net metering in some states, you get full retail rate credit for the amount of electricity you send back into the grid with your solar panels.
Net Metering requires your utility to monitor how much energy your solar power system produces and how much energy you actually consume, and make sure you get credit for the surplus.
Full retail residential net metering is good for home solar systems up to 20 kW in capacity. In South Carolina, utilities must roll over your monthly excess generation to the next month and pay you for your annual excess at the end of the year.
There is no cap on net metering until June, 2021, so it’s a good idea to go solar until then to make sure you’re entitled to all your credits when you generate more solar than you use during the middle of the day with a home solar system here in South Carolina.
Utilities are in the process of reviewing and proposing a successor program to net metering. It’s most probably not going to be as favorable to homeowners as what’s in place now.
Duke Energy has also begun a fast track program for smaller solar systems like you’d install on your home to be connected to the grid. It has a $500 application fee, and requires an external disconnect (which is probably unnecessary).
South Carolina solar rebates
While South Carolina does not have a dedicated state rebate for solar panel installation, some manufacturers like LG offer their own solar rebates. These programs are usually time sensitive. For example, LG offers a $600 solar rebate on their equipment, which your installer can help you redeem over the next year.
If you’re lucky enough to be a Santee Cooper power customer, you can qualify for a generous solar energy rebate. You can get $600 per kilowatt (kW) up to a maximum of 6 kW. So, for an average sized 6kW system, you can get $3,600 of your installation cost back right away.
Note: In the unlikely event there are less than 210 participants in this program for 2020, you can receive $1,200 per kW up to 6 kW.
South carolina solar tax credit
The state legislature has scored a slam dunk with South Carolina’s Solar Energy Tax Credit. When you install a residential solar power system here, you’re entitled to claim a state tax credit of 25% of the purchase and installation costs. That’s a whole lot of taxes you won’t be paying in April.
The maximum credit that can be applied in a single tax year is $3,500 or 50% of your state tax liability, whichever is less. Unused credit may be carried forward for 10 years. Score for South Carolina!
Here's an example of how the South Carolina tax credit works: Say you're a married couple making $75,000/yr. Your income tax for 2021 will be $3,271, and half of that is $1,636. Your 5-kW solar system costs $16,250, meaning you're eligible for a state tax credit of $4,063 (25% of the cost). You take the max in year 1, $1,636, and assuming your income is roughly the same in year 2, another $1,636 in year 2. That leaves you with an unused tax credit of $791 that you can take in year 3.
Don't forget: All solar installations are eligible for a tax credit from the Feds as well. There's no cap on the federal tax credit and fortunately for South Carolina, having no state rebate to deduct means a larger tax credit coming your way. The two tax credits combined can wipe out 55% of the costs to install solar in just a few short years. Wow!

I chose Renu for our solar install based on their competitive pricing and their history of working in the Carolinas. The team was responsive and quick to address concerns and scheduling was a breeze. We've been thrilled with our panels since the project was completed!

From my first contact with Tom Ferraro through flipping the switch to solar, I can't imagine a better experience. Tom and my project manager made sure that I was kept informed of the schedule and progress every step of the way. They answered all my questions and responded promptly to any concern. I highly recommend Carolina Energy Conservation for anyone who is considering going solar.

What a FANTASTIC company!<br />When we decided to go with Sunstore Solar (out of 5) we were hoping we would not be let down once they had a signed contract and deposit. Sunstore has more than exceeded our expectations. We did not have to worry about any paper work dealing with Blue Ridge Electric Co-op, tax forms or county regulations. Sunstore did not pressure us into more wattage than we were looking for (50% offset) or a ground mounted system. Sunstore LISTENED to what we wanted and why. They were always able to answer our questions and continue to do so. <br /><br />Ashley Edwards (our sales rep) is extremely knowledgeable. He heard our concerns/wants assuring our energy needs were met with no problems or delays. He took the time to talk instead of just trying to make a sale. Ashley gave us several options, explained what was required for each and let us decide, not right then but a couple of weeks later.<br /><br />The installation crew were outstanding and very professional. They showed us during the install on site, what they were planning to do and why. Pre-Pictures are great but before someone does work on your roof it was nice to have that "wait a moment" minute and have it shown again. <br /> <br />We have very, very good looking aesthetic system (pictures online), no gaps from vent pipes and no electrical piping running all over the roof.<br /><br />Sunstore made the entire process exciting and enjoyable.<br />Use Sunstore for your solar needs, you will not regret it.

We are approaching 2 years since Cape Fear Solar installed a system on our home, and I’m still very pleased with our system and our overall experience. When I contacted Cape Fear Solar for a quote, they sent a friendly and knowledgeable associate to our home who worked with us to design a system to meet our needs. They were helpful in answering our questions and did not pressure us into a sale. The process of planning, installing, and getting set up was very smooth, and someone from CFS was constantly in contact with us keeping us informed. They even went as far as to challenge Progress Energy when we were initially denied for their solar incentive. This resulted in us getting a $5,000 rebate from Progress to put towards our system. Over the years, I have referred several friends to Cape Fear Solar, and they have all reported similar and great experiences. Making the leap to change to powering your home with solar can be intimidating, but the financial benefits and peace of mind knowing that we are reducing our harm to our Earth is so valuable. Working with Cape Fear Solar made this process feel easy and gave us the confidence that we were doing the right thing. In my experience, switching to solar has been a great decision financially, and it feels good to be part of the solution rather than part of the problem. Thank you Cape Fear Solar for making this possible.

Bill and Daniel are amazing! Bill helped us design a solar unit for our home and he made it so easy for us to understand the entire process from solar production, costs, and installation. He was very transparent through all aspects of the project and had immediate answers to our questions. His team communicated with my HOA and Dominion Energy so we didn't have to lift a finger through the entire process. The installation team was respectful to our home and were efficient with their time. Right now, we have $0 electric bills and we couldn't be happier with our system! Thank you Bill and Daniel for providing such a high level of service and following through with all that you offer. I would defiantly recommend reaching out to Super Green Solutions if you are interested in getting solar…Now is the time!!!

I got a small residential rooftop solar system installed by Alder and they were great. In the sales process, they were very professional and attentive to any questions I had. Communication was good while the system was getting permitted and while we scheduled our installation. The installation went smoothly and the crew was friendly. I got the system turned on quickly after installation and I am now producing my own power and it feels great.
