What you're paying for: a 5 kW system in Sandton
Roughly 40% of a fully-installed quote is the panels themselves; the rest is split between inverter, mounting, cabling, labour, and the certificate of compliance (CoC). Here's a typical decomposition for a 5 kW system installed in Sandton:
Solar panels (10–12 × 450W) Tier-1 monocrystalline (Canadian Solar, JA Solar, Trina) — the cheapest part to swap brand on | R35 000 |
Hybrid inverter (5–6 kW) Sunsynk, Deye, Goodwe, or Solis. Single biggest cost lever you can negotiate. | R19 300 |
Mounting & rails Galvanised or aluminium roof rails, plus marine-grade clamps near the coast | R7 900 |
DC + AC cabling, BoS MC4 connectors, breakers, isolators, surge protection, earthing | R8 800 |
Installation labour 1–2 day install with a 2-3 person team — varies by roof complexity | R12 300 |
Permit + CoC certificate Required by your municipality before grid-tie commissioning | R4 400 |
| 5 kW total — installed in Sandton | R87 500 |
At Sandton's tariff (R3.08/kWh), what does this earn you back?
A 5 kW system at Sandton's PVGIS yield (1 820 kWh/kWp) generates about 9 100 kWh/year. At 60–85% self-consumption (no battery vs. with battery) and the local tariff, that's roughly R1 401–R1 985/month off your bill, before tariff escalation.

FAQ — solar cost in Sandton
How much does a solar system cost in Sandton?
A grid-tied solar system in Sandton costs between R57 500 (3 kW) and R172 500 (10 kW), fully installed. Adding a battery adds roughly R30,000–R80,000 depending on capacity.
Why is solar more expensive in Sandton than other cities?
Sandton prices track the national mid-market average. The biggest variables are roof complexity (single-storey IBR roofs are cheapest), distance from your DB board, and inverter brand.
What's the cheapest part of a solar install I can negotiate on?
Inverter brand and battery (if included) are the two biggest cost levers. A Goodwe inverter is typically R5,000–R10,000 cheaper than the equivalent Sunsynk; a 5.1 kWh LiFePO4 battery from a tier-2 brand is R10,000–R15,000 cheaper than a Pylontech US3000C. Don't compromise on mounting, cabling, or earthing — failures here cost more to fix than you saved.
What's NOT included in the headline price in Sandton?
Most quoted prices include panels, inverter, mounting, cabling, basic BoS, labour, and CoC certification. They usually exclude: battery backup, DB board upgrades (often needed in older homes), special roof access (slate, complex pitches), monitoring subscriptions beyond year 1, and SARS Section 12B claim assistance.
Does the price include the SARS Section 12B rebate?
No — quoted prices are gross. The Section 12B rebate is claimed via your ITR12 income-tax return after installation. For an individual taxpayer in the 36% bracket installing a 5 kW system in Sandton, the deferred tax benefit can recover R20,000–R30,000 over the depreciation period.
