South Carolina Solar Installer Checklist: How to Verify and Protect Yourself
South Carolina's solar market has grown rapidly, with over 250 companies now operating across the state. The combination of generous state tax credits, net metering policies, and abundant sunshine has attracted both legitimate installers and predatory operators. Before signing any solar contract in SC, you need a systematic approach to verify the company and protect your investment.
This guide provides South Carolina homeowners with a comprehensive vetting checklist, explains the state's 25% solar tax credit (and the lies some companies tell about it), and identifies SC-specific red flags that should make you walk away.
South Carolina Solar Licensing
Understanding SC Contractor Requirements
South Carolina requires solar installers to hold appropriate contractor licenses. Understanding the licensing landscape is your first line of defense.
| License Type | Issuing Authority | Scope |
|---|---|---|
| Electrical Contractor | SC Department of Labor, Licensing, and Regulation (LLR) | Required for all solar electrical work |
| General Contractor | SC LLR | May be required for larger installations or structural modifications |
| Mechanical Contractor | SC LLR | May be required for solar thermal installations |
| Specialty Contractor | SC LLR | Limited scope; verify that solar is within the specialty |
How to Verify a South Carolina License
- Visit the SC LLR website
- Use the "Licensee Lookup" tool
- Enter the contractor's name or license number
- Verify:
| What to Check | What to Look For |
|---|---|
| License status | Active and current |
| License type | Appropriate classification for solar work |
| Expiration date | Not expired or about to expire |
| Disciplinary actions | Any past or pending complaints |
| Bonding | Required bonds on file |
| Insurance | Workers' compensation and general liability |
SC LLC Verification
Many solar companies in South Carolina operate as LLCs. Verify the company's corporate status:
- Search the SC Secretary of State database for the company name
- Confirm the LLC is active and in good standing
- Check the registered agent — this should be a real person or registered agent service in SC
- Note the formation date — be cautious of companies formed recently (less than 2 years)
Warning: Some fraudulent companies create multiple LLCs to shed complaints. If a company recently changed names, investigate the previous entity.
The 25% Tax Credit — What Companies Get Wrong
Understanding the SC Solar Tax Credit
South Carolina offers a 25% state tax credit for solar installations, in addition to the 30% federal Investment Tax Credit (ITC). Combined, these credits can offset up to 55% of your system cost. However, solar companies frequently misrepresent how this credit works.
| Credit | Rate | Maximum | Carryforward |
|---|---|---|---|
| Federal ITC | 30% of system cost | No state cap | 5 years |
| SC State Credit | 25% of system cost | $3,500 per year | 10 years |
| Combined | Up to 55% | Varies by system cost | As above |
Common Tax Credit Lies
| The Lie | The Truth |
|---|---|
| "You'll get the full $3,500 credit in year one" | The SC credit is capped at $3,500 per year. If your total credit exceeds $3,500, you carry the remainder forward for up to 10 years. |
| "The tax credit is a check from the government" | Tax credits reduce your tax liability — they are not direct payments. If you owe no state income tax, the SC credit provides no benefit that year (though you can carry it forward). |
| "We'll guarantee your tax credit amount" | No solar company can guarantee your tax liability or credit eligibility. Your actual credit depends on your income, filing status, and total tax obligation. |
| "The credit covers the full 25% immediately" | The annual $3,500 cap means a $30,000 system generates a $7,500 state credit, but you can only claim $3,500 per year — taking over 2 years to realize the full benefit. |
| "Everyone qualifies for both credits" | You must have sufficient tax liability to benefit from tax credits. Retirees with minimal income may not benefit from the state credit. |
How to Verify Tax Credit Claims
Before trusting any company's savings calculations that include tax credits:
- Consult a tax professional — Have a CPA or enrolled agent review your tax situation
- Calculate your state tax liability — Review last year's SC tax return (SC1040)
- Understand the carryforward — Know how long it will take to realize the full credit
- Get the credit amount in writing — Ask the company to document their tax credit assumptions
- Do not count credits you cannot use — If your tax liability is low, the credit may be worth less than claimed

South Carolina-Specific Red Flags
SC-Specific Warning Signs
| Red Flag | Why It's Dangerous |
|---|---|
| "Your tax credit will cover the down payment" | Tax credits are received when you file taxes — months after purchase. You must finance or pay the full amount upfront. |
| "We're SCE&G/Duke Energy approved" | Utilities do not approve or endorse specific solar companies. They only approve system interconnection. |
| "Sign now before the tax credit expires" | The SC solar tax credit does not have an expiration date for residential installations. There is no deadline pressure. |
| "We're based in Charlotte/Atlanta but licensed in SC" | Out-of-state companies may be less responsive for warranty and service issues. Verify their SC licensing carefully. |
| "We'll handle everything with your utility" | You should understand the interconnection process yourself. Some companies misrepresent utility net metering policies. |
| "Our system qualifies for special SC rebates" | South Carolina does not currently offer statewide solar rebates beyond the tax credit. Check dsireusa.org for verified programs. |
Pressure Tactics to Watch For
South Carolina's consumer protection laws prohibit certain high-pressure sales tactics, but enforcement requires reporting. Watch for:
- "This price is only good today" — Artificial urgency
- "Your neighbor just signed" — False social proof
- "The tax credit is going away this year" — False deadline
- "I need to call my manager for approval" — Theatrical negotiation tactic
- "This government program ends soon" — Non-existent program
Understanding Your Solar Contract in SC
Key Contract Terms to Review
| Contract Element | What to Verify | Common Issues |
|---|---|---|
| System price | Total cost per watt ($/W DC) | Price above $3.50-$4.00/W may be overpriced |
| Equipment specs | Panel brand, model, wattage, inverter type | Substitution of cheaper equipment |
| Production estimate | Annual kWh estimate with methodology | Overestimated production |
| Installation timeline | Specific start and completion dates | Vague or missing timeline |
| Payment schedule | Tie payments to milestones, not dates | Large upfront payments requested |
| Cancellation terms | 3-day right to cancel clearly stated | Cancellation rights buried or hidden |
| Escalation clause | Annual rate increase for PPAs/leases | Hidden escalation that compounds over time |
| Buyout provision | Terms for purchasing the system | Unfavorable buyout formula |
Cancellation Rights in South Carolina
South Carolina provides a 3-day right to cancel for home solicitation sales under Section 39-5-145 of the SC Code:
- Applies to sales made at your home totaling more than $50
- The company must provide a written cancellation form
- You must send written cancellation within 3 business days
- The company must refund all payments within 10 days
- The company must pick up any equipment within 20 days
Important: Mark your calendar the moment you sign. If you have any doubts, exercise your cancellation right immediately. For more on cancellation, read our guide on canceling door-to-door solar contracts.
Financing Options and Traps
Comparing Solar Financing in SC
| Financing Type | How It Works | Pros | Cons |
|---|---|---|---|
| Cash purchase | Pay full cost upfront | Lowest total cost; maximizes tax credits; you own the system immediately | Requires significant cash on hand |
| Solar loan | Finance the system over 10-25 years | You own the system; eligible for tax credits; fixed payments | Interest adds to total cost; dealer fees may apply |
| Solar lease | Rent the system for 20-25 years | Low or no upfront cost; maintenance included | No tax credit eligibility; no equity; hard to sell home |
| PPA | Pay for power produced at a per-kWh rate | No upfront cost; pay only for production | No tax credits; escalating payments; complex contracts |
Dealer Fee Warning
Many solar loans include a dealer fee — an origination fee charged by the lender and financed into the loan. This fee is typically 15-30% of the system cost and can add $5,000-$15,000 to your total cost.
| Loan Type | Typical Dealer Fee | Advertised Rate | Actual Cost |
|---|---|---|---|
| Low-APR loan | 20-30% | 0.99-2.99% | Higher than it appears due to fee |
| Standard loan | 5-15% | 5.99-8.99% | More transparent overall cost |
| No-fee loan | 0% | 7.99-10.99% | Sometimes cheaper in total despite higher rate |
Rule of thumb: Always calculate the total cost over the life of the loan — not just the monthly payment. A $30,000 system with a 25% dealer fee financed at 1.99% over 25 years can cost more than a $30,000 system with no dealer fee financed at 7.99% over 15 years.
For more on dealer fees, see our solar dealer fees explained guide.
Common Lenders in South Carolina
| Lender | Typical Products | Known Issues |
|---|---|---|
| GoodLeap | Solar loans | High dealer fees; aggressive collection practices |
| Mosaic | Solar loans | UCC-1 filings on equipment; slow dispute resolution |
| Dividend Finance | Solar loans | Loans sold to debt buyers; communication issues |
| Sunlight Financial | Solar loans | Company faced financial difficulties; loan servicing concerns |

FAQ
How do I verify a solar installer's license in South Carolina?
Visit the SC Department of Labor, Licensing, and Regulation website at llr.sc.gov and use the Licensee Lookup tool. Search by the contractor's name or license number. Verify that the license is active, the classification covers solar work (typically an electrical contractor license), and there are no disciplinary actions. You can also call LLR at (803) 896-4300 for verification assistance.
Is the South Carolina 25% solar tax credit still available?
Yes, the South Carolina solar tax credit of 25% of the total system cost is currently available for residential solar installations. The credit is capped at $3,500 per year against your state income tax liability, with unused amounts carrying forward for up to 10 years. This credit is separate from the federal 30% Investment Tax Credit. However, your ability to use the credit depends on having sufficient state tax liability. Consult a tax professional to understand your specific situation.
What should I do if a solar company lied about the tax credit?
If a solar company made false representations about the SC tax credit — such as claiming you would receive a check from the government, guaranteeing a specific credit amount, or misrepresenting how the credit works — you may have a claim under the South Carolina Unfair Trade Practices Act (UTPA). Document exactly what was said (dates, names, written materials), file a complaint with the SC Department of Consumer Affairs, and consider consulting with a solar fraud attorney.
Can I cancel a solar contract in South Carolina?
Yes. South Carolina law provides a 3-day right to cancel for home solicitation sales (sales made at your residence) over $50. You must submit written cancellation within 3 business days of signing. The company is required to provide a cancellation form with the contract. Send your cancellation by certified mail and keep proof of delivery. If you are beyond the 3-day window, cancellation becomes more difficult but may still be possible if the company committed fraud or breached the contract. See our guide to canceling solar contracts for details.
