Panel pricing guide
Solar Panel Prices in South Africa
Understand panel-only retail prices versus fully installed system cost per watt — and why the gap exists.
Direct answer: Panel-only prices often sit around R3.5–R6.5/W, while our current all-in installed grid-tied assumption is about R19.0/W (hybrid ~R26.0/W), based on 450 W modules.
Installed assumptions as of 2026-07-24 · Installed per-watt figures are all-in guide prices including panels, inverter, mounting, labour, CoC and VAT. Hybrid pricing includes a typical lithium battery (about 2 kWh per kWp). Panel-only retail prices exclude installation.Panel price vs installed system price
A cheap panel advert is not a turnkey solar system. Installation adds inverter, mounting, cabling, labour, compliance and VAT.
Typical panel counts
- 3.00 kW: 6–8 × 450 W panels (≈ 13.3–16.8 m²)
- 5.00 kW: 11–13 × 450 W panels (≈ 22.8–28.8 m²)
- 8.00 kW: 17–19 × 450 W panels (≈ 34.2–43.2 m²)
- 10.00 kW: 22–24 × 450 W panels (≈ 43.7–55.2 m²)
- 12.00 kW: 26–28 × 450 W panels (≈ 51.3–64.8 m²)
- 16.00 kW: 35–37 × 450 W panels (≈ 68.4–86.4 m²)
Warranty and degradation
Most modern modules offer 10–15 year product warranties and 25+ year linear performance warranties. Our financial models assume gradual annual output decline — see the methodology on your personalised report.
Frequently asked questions
What is a typical solar panel price in South Africa?
Retail panel-only prices often fall roughly between R3.5 and R6.5 per watt, while fully installed grid-tied systems are closer to R19.00 per watt all-in in our current assumptions.
Why is installed cost much higher than panel cost?
Installation adds the inverter, mounting, cabling, labour, compliance and VAT. Comparing a panel sticker price to an installed quote is misleading.
