Solar geysers in Johannesburg
A solar geyser heats your water directly from the sun, and Johannesburg gets about 6.2 peak sun hours a day. Water heating is one of the larger electricity loads in many homes, so it is often worth pricing on its own. Request solar geyser quotes for Johannesburg, or read more on our solar geysers page.
Solar in Johannesburg: common questions
How much does solar cost in Johannesburg?
A 5 kW grid-tied solar system typically costs roughly R55k–R80k installed in Johannesburg (about R11 to R16 per watt), with no battery. Roof type, brand and installer all move the price, so treat this as a guide and compare written quotes.
Is Johannesburg sunny enough for solar?
Johannesburg receives about 6.2 peak sun hours a day on a well-angled panel. PVGIS models a 5 kW system there at around 731 kWh a month on average, from about 634 kWh in February to 831 kWh in August. An installer's site assessment gives the real figure for your roof.
Are there solar rebates or tax incentives in Johannesburg in 2026?
Not for homeowners. The Section 6C rooftop solar incentive covered new PV panels brought into use between 1 March 2023 and 29 February 2024 (it expired on 29 February 2024) and has not been renewed; solar geysers never qualified. Businesses can still claim accelerated allowances for renewable energy under Section 12B. Confirm the details with a tax practitioner.
Should I choose a solar geyser or a solar PV system?
A solar geyser only heats water, so it costs less than a full PV system but powers nothing else. A PV system produces electricity for the whole home and, with a battery, can keep essentials running during outages. You can request quotes for either, or both, and compare.
