How payback works

Estimated payback

Saved per year
Solar's return is its payback period: annual bill savings against net system cost. In 2026, without the federal credit, that payback is longer but still real where rates and net metering are favorable.
Spot a fair quote in Florence
A typical solar installation here runs $12,400–$16,200. A trustworthy quote shows a production estimate (kWh/year) and the net cost after incentives, not just a monthly payment. Be cautious of door-to-door pressure.
- Get the production estimate in kWh and the net cash price.
- Confirm the net-metering rate your utility currently pays.
- Compare buying vs lease/PPA; ownership keeps the long-run return.
What changes your price
- System size (kW). Sized to your annual usage and roof space; bigger arrays cost more but produce more.
- Panel tier & inverter. Premium high-efficiency panels and microinverters cost more per watt.
- Roof complexity. Steep, multi-plane, or shaded roofs add labor and may need more equipment.
- Battery storage. Adding storage roughly increases project cost by half but adds backup power and self-use value.

Why it matters
Why it pays to do it right
Lock in your electricity rate
Solar trades a volatile monthly bill for a fixed up-front cost, hedging against future utility rate increases over the system's life.
Payback is the real question
With the federal credit gone in 2026, the honest math is production times your local rate versus net cost. We show that payback plainly, no inflated promises.
Net metering rules drive the return
Where your utility still offers it, net metering credits the power you export, and that buyback rate is often the single biggest swing factor in your return. Several states have scaled it back, so confirm your utility's current policy.
Pairs with a sound roof
Panels last 25+ years, so install on a roof with plenty of life left. If your roof is near end-of-life, replace it first.
Local conditions
Solar in Florence
The Pee Dee region's Florence area averages about 4.9 peak sun hours per day, strong for the Southeast, and South Carolina's net metering requirement means that excess solar production earns a retail-rate credit against future Duke Energy or Pee Dee Electric bills. The combination makes rooftop solar a real performer in Florence.
Peak sun hours
~4.9/day
The Coastal Plain's open skies deliver consistent production per installed kW across the Florence area year-round.
Utility rate
~13 cents/kWh
The rate you offset drives the payback; at 13 cents per kWh, right-sizing to your load keeps the economics solid.
Annual output
~1,410 kWh/kW
A typical Florence-area production factor per installed kW, reflecting the Pee Dee's strong sun and low shading on most residential roofs.
Net metering and incentives
South Carolina law (SCPSC Order 2017-512C) requires Duke Energy Progress and Pee Dee Electric to offer net metering, crediting excess solar generation at the retail rate against future Florence utility bills. That buyback rate, combined with roughly 4.9 peak sun hours per day, drives the payback math in Florence. South Carolina also offers a 25% state income tax credit on the net cost of a solar system, spread over up to ten years, which meaningfully shortens the payback period for Florence homeowners.
Permits
Rooftop solar in Florence requires a building permit, electrical permit, and utility interconnection approval with Duke Energy or Pee Dee Electric.
FAQ
Solar questions, answered for Florence
Is solar worth it in Florence without the federal credit?
Yes, for many Florence homeowners. The combination of South Carolina's 25% state income tax credit (spread over up to ten years), net metering at retail rate, and about 4.9 peak sun hours per day keeps payback in the 9--14 year range for most systems. The federal 25D credit expired December 31, 2025, so the state credit and net metering now carry most of the financial case.
How does net metering work in Florence?
Under South Carolina's net metering rules, Duke Energy Progress and Pee Dee Electric credit excess solar production at your retail rate and apply those credits to future bills. Confirm your utility's current rate schedule and any system-size caps before signing a contract.
What is the South Carolina state solar tax credit?
South Carolina offers a 25% income tax credit on the net cost of a solar system, claimable over up to ten years. It applies to most residential grid-tied systems in Florence and stacks with net metering savings for the strongest overall return.
How do I size a solar system for my Florence home?
Start with 12 months of Duke Energy or Pee Dee Electric bills to find your average monthly kWh usage, then divide by the monthly output per kW for Florence (roughly 117 kWh per kW per month). A licensed installer will size the array and confirm the roof can support it.
