Frequently Asked Questions
How much do solar panels cost in Charleston?
Solar panel costs in Charleston typically range from $2.50-$3.50 per watt. A standard 8kW residential system costs $20,000-$28,000. The 30% federal residential tax credit expired on December 31, 2025, so this is the full out-of-pocket cost. South Carolina state and local incentives, net metering, and SRECs may help reduce your net cost.
Who is the best solar installer in Charleston?
The best solar installer in Charleston depends on your needs, budget, and project type. Check ratings, reviews, certifications (NABCEP), and experience on this page. Get quotes from at least three installers to compare.
How long does solar installation take?
Physical installation takes 1-3 days. The full process from contract to Permission to Operate typically takes 6-12 weeks, including design, permitting, installation, inspection, and utility interconnection.
Do I need permits for solar panels?
Yes. Solar installations require building and electrical permits. Your installer handles all permitting, including HOA approval and utility interconnection. Some jurisdictions use SolarAPP+ for same-day automated approvals.
What solar incentives are available in Charleston?
The 30% federal residential clean energy tax credit (ITC) expired on December 31, 2025. However, South Carolina may offer state-level incentives such as rebates, performance-based incentives, or solar renewable energy certificates (SRECs). Net metering policies vary by utility - check with your local utility in Charleston to see if they offer full retail credit for exported solar power. Your installer should walk you through all available incentives during the quoting process.
How much can I save with solar panels in Charleston?
Savings depend on your electricity rate, system size, and sun exposure. A typical 8kW system offsets $1,400-$2,400 per year in electricity costs. Over 25 years, total savings typically range from $25,000-$50,000. Your installer can provide a detailed savings estimate based on your specific utility rate and energy usage.
Should I get battery storage with my solar panels?
Battery storage ($12,000-$18,000 installed) is worth considering if you have time-of-use electricity rates, experience frequent power outages, or want energy independence. Without favorable net metering, batteries help you use more of your own solar power instead of exporting it at lower rates. Popular options include Tesla Powerwall, Enphase IQ Battery, and Franklin WH.
What equipment should I look for?
Top-tier solar panels include REC, Q Cells, Canadian Solar, and Silfab. For inverters, Enphase microinverters (25-year warranty) and SolarEdge optimizers are the most popular. Your installer should offer multiple equipment options at different price points and explain the trade-offs.
