Solar Water Heaters: A Bright Solution to Load Shedding in South Africa


In South Africa, where load shedding is a common occurrence, the need for reliable and sustainable energy sources has never been greater. One such solution is solar water heating. Not only does it offer a way to reduce energy costs, but it also provides a dependable source of hot water during power outages.

The Power of Solar Water Heating

Solar water heaters harness the power of the sun to heat water, reducing the need for electricity. This is particularly beneficial in South Africa, where sunshine is abundant. By using solar energy, households can have access to hot water even during periods of load shedding.

Solar Geyser Conversions vs Full Solar Geysers

There are two main types of solar water heaters: solar geyser conversions and full solar geysers.

Solar Geyser Conversions

A solar geyser conversion involves integrating a solar collector into an existing electric geyser system. The solar collector heats the water, which then flows, via a circulation pump and solar controller called a GeyserWise into the geyser for storage. This system is cost-effective as it utilizes the existing geyser and only requires the addition of a solar collector.

Full Solar Geysers

A full solar geyser, on the other hand, is a complete system with its own storage tank located on the roof. The solar collector heats the water, which is then stored in the tank. This system is more efficient as it reduces heat loss, but it is also more expensive due to the cost of the storage tank and its installation.

The Benefits of Solar Water Heaters in South Africa

With load shedding being a regular occurrence in South Africa, having a reliable source of hot water is essential. Solar water heaters provide this reliability. They also offer significant cost savings over time, as the sun’s energy is free. Additionally, by reducing reliance on electricity, solar water heaters contribute to environmental sustainability.


Solar water heaters offer a bright solution to the challenges of load shedding in South Africa. Whether you choose a solar geyser conversion or a full solar geyser, you’ll be investing in a sustainable and reliable source of hot water for your home.
