Solar Geyser Installation & Prices

A solar geyser uses South Africa's abundant sunshine to heat water, cutting the electricity your geyser uses and keeping you less dependent on Eskom. Whether you want a complete new system or a conversion of your existing geyser, choosing the right setup makes all the difference.

Types of solar geyser systems

Installers will talk you through a few choices:

Evacuated tube vs flat plate: evacuated tubes tend to perform well in cold weather and frost-prone areas, while flat plate collectors are robust and simple
Direct vs indirect: direct systems heat the water itself; indirect systems heat a fluid that passes through a heat exchanger, which helps in frost areas or with hard water
High pressure vs low pressure: high-pressure systems give mains-pressure showers; low-pressure systems are simpler but give weaker flow
Retrofit kits: add collectors to your existing electric geyser rather than replacing it

Solar geyser installation and price factors

We do not quote a fixed solar geyser price. What drives the cost of solar geyser installation:

Tank size in litres and the number of collectors or tubes
Whether it is a full system or a retrofit conversion
Roof type, pitch, orientation and access
Pipework, valves, pumps and controllers needed
Electric backup and timer settings for cloudy days

SANS 10106 covers the installation of solar water heating systems, and a qualified plumber should issue a CoC for the plumbing work.

Is a solar geyser worth it?

Heating water is one of the biggest electricity costs in many homes, and much of South Africa gets strong sun for most of the year. A well-sized, correctly installed system can reduce how often your element needs to switch on. Savings depend on your household's hot water use, the system type, how the backup element is controlled, and how well the system is maintained. Ask installers to explain their sizing and expected performance for your household rather than relying on general claims. Good installers also explain how to check the system and what maintenance it needs, such as cleaning collectors and inspecting valves and anti-frost protection.

Choosing a plumber for solar geyser installation

The cheapest price is not always the best value. When your quote arrives, check:

Registration: ask for the plumber's PIRB registration and whether a Certificate of Compliance is included where the work needs one.
Scope: make sure the quote lists materials, labour, call-out fees and any making good of walls, ceilings or paving.
Guarantee: find out how long the workmanship is guaranteed and what manufacturer warranties apply.
Timing: confirm when the work can start and how long the water will be off.

Our service puts your request in front of a plumber in your area so you can check these points before you commit. It costs nothing and there is no obligation to accept the quote.

What to include in your request

Your household size or daily hot water use
Whether you want a full system or a retrofit of your current geyser
Your roof type and which direction it faces
Whether your area gets frost or has hard water

Frequently asked questions

Can my existing geyser be converted to solar?

In many cases, yes. A retrofit kit adds collectors and a pump to your current geyser. Your installer will check the geyser's age, condition and position before recommending it, and may suggest replacing a very old geyser at the same time.

Will a solar geyser give hot water on cloudy days?

Most systems keep an electric element as backup, controlled by a timer or controller, so you still have hot water in poor weather. Savings depend on your usage and climate.

Do you install solar geysers?

No. We are a free quote service. An independent installer quotes you directly and is responsible for the installation.
