Installed cost by system size
Every figure below is the fully installed price including VAT, the inverter, the battery capacity shown, mounting and labour. It excludes municipal registration fees and any distribution board rework your home turns out to need.
| System | Battery | Installed price | Typically suits |
|---|---|---|---|
| 3 kW hybrid | 5 kWh | R55 000 – R90 000 | A flat or small home running lights, plugs, TV and wifi through load shedding. |
| 5 kW hybrid | 5–10 kWh | R75 000 – R120 000 | The most common residential system. A 2–3 bedroom home without electric geyser or pool. |
| 8 kW hybrid | 10 kWh | R120 000 – R180 000 | A family home with a heat pump or geyser element on the backed-up circuit. |
| 10 kW hybrid | 15 kWh | R150 000 – R250 000 | A large home, or one with a pool pump and borehole to carry. |
What the parts cost on their own
Useful for checking an itemised quote line by line. If a quote is not itemised, ask for one that is. It is the single most effective thing you can do to compare installers fairly.
| Solar panel (per panel, 550–590 W) | R1 350 – R2 700 |
| Installed cost per kW (all-in) | R15 000 – R18 000 |
| Labour, 5 kW system | R10 000 – R15 000 |
| Labour, 8 kW system | R14 000 – R20 000 |
| Labour, 10 kW system | R18 000 – R25 000 |
| Battery storage, added | R25 000 – R75 000 |
What actually drives the price
Battery capacity. Storage is usually the largest single line and the biggest difference between two quotes for the same array. Compare usable kWh, not nominal kWh, because depth of discharge differs by chemistry, and a 10 kWh battery you can only draw 8 kWh from is an 8 kWh battery.
Single phase versus three phase. A three-phase supply needs a three-phase inverter or a multi-inverter setup, which costs materially more than the single-phase equivalent of the same capacity.
Roof type and pitch. Tile roofs take longer to mount than IBR or corrugated sheeting, and flat roofs need ballasted or tilt-frame mounting. This lands in the labour line rather than the equipment line.
Distance to the distribution board. Long cable runs mean thicker cable and more labour. It is the most commonly underestimated cost in a first quote.
Compliance and registration. A certificate of compliance is not optional, and most municipalities require registration as small-scale embedded generation before commissioning. Check whether both are in the quote or excluded from it.
What the same system produces in each province
Cost is only half of payback. The other half is yield, and that varies by province. Each 1 kW of panels produces roughly its province's peak sun hours in kWh on an average day, before real-world losses of around 20%.
| Province | Peak sun hours/day | 8 kW array, daily | Certified installers |
|---|---|---|---|
| Northern Cape | 9.6 | About 61 kWh | 13 |
| Western Cape | 9.1 | About 58 kWh | 78 |
| Limpopo | 8.9 | About 57 kWh | 18 |
| North West | 8.8 | About 56 kWh | 10 |
| Free State | 8.6 | About 55 kWh | 10 |
| Gauteng | 8.5 | About 54 kWh | 203 |
| Mpumalanga | 8.3 | About 53 kWh | 20 |
| Eastern Cape | 7.8 | About 50 kWh | 18 |
| KwaZulu-Natal | 7.4 | About 47 kWh | 40 |
The tax position in 2026
Individuals cannot claim anything. The Section 6C rebate, worth 25% of panel cost up to R15 000, applied only to panels brought into use between 1 March 2023 and 29 February 2024. It was not extended, and no replacement residential incentive has been introduced since.
Businesses can. Section 12B allows a 100% deduction in the first year for qualifying renewable energy assets under 1 MW; larger assets are written off 50/30/20 across three years. Section 12B has no expiry date.
The enhanced allowance has closed. The 125% Section 12BA allowance applied only to assets brought into use between 1 March 2023 and 28 February 2025.

Solar installation cost: common questions
How much does solar installation cost in South Africa?
Between R55 000 and R250 000 installed for a residential hybrid system including battery and VAT. A 5 kW system, the most common size, runs R75 000 to R120 000. Larger systems cost more in total but less per kilowatt, typically R15 000 to R18 000 per kW all-in.
How much does solar panel installation labour cost?
Labour on its own is typically R10 000 to R15 000 for a 5 kW system, R14 000 to R20 000 for 8 kW and R18 000 to R25 000 for 10 kW. A single 550 to 590 W panel costs R1 350 to R2 700 before installation. A quote that does not separate labour from equipment is hard to compare, so ask for an itemised one.
Is solar still worth it in South Africa?
It depends on your tariff and how much you use during daylight. Solar displaces electricity you would otherwise buy, so the higher your tariff and the more you consume in the day, the faster it pays back. A battery adds cost and shortens outages but does not itself generate anything, so backup and savings are two separate decisions that get bundled into one quote.
Can individuals still claim a solar tax rebate?
No. The Section 6C rebate for individuals, worth 25% of panel cost up to R15 000, applied only to panels brought into use between 1 March 2023 and 29 February 2024. It was not extended. Businesses can still claim under Section 12B, which allows a 100% first-year deduction for renewable energy assets under 1 MW.
What is Section 12B and who qualifies?
Section 12B of the Income Tax Act lets a business deduct the full cost of a qualifying renewable energy asset under 1 MW in the year it is brought into use. Larger assets are written off 50/30/20 over three years. The enhanced 125% allowance under Section 12BA applied only to assets brought into use between 1 March 2023 and 28 February 2025 and has closed.
Do I need municipal approval to install solar?
In most South African municipalities a grid-tied or hybrid system must be registered as small-scale embedded generation before it is commissioned. The application generally needs a certificate of compliance and a signed electrical drawing. Requirements and turnaround times differ by municipality, so confirm your installer handles the submission for yours.
How much does a solar battery cost on its own?
Adding storage to a system costs roughly R25 000 to R75 000 depending on capacity and chemistry. Battery capacity is usually the single largest swing factor between two quotes for the same panel array, so compare kWh of usable storage rather than the headline system size.
How long does a solar installation take?
The physical installation of a residential system is usually one to three days. The longer part is paperwork: the certificate of compliance, and the municipal small-scale embedded generation registration, which varies by municipality. Ask for both timelines separately when you compare quotes.
Why do quotes for the same system size differ so much?
Because nominal size describes the panels, not the system. Battery capacity, inverter brand and whether it is single or three phase, mounting hardware for your roof type, cable runs to the distribution board, and whether the certificate of compliance and municipal registration are included all move the total. Two quotes for a 5 kW system commonly differ by R30 000 to R50 000.
