Installation prices

Solar geyser systems

Nine configurations across close-coupled, flat-roof, split and retrofit systems. All prices include supply and standard installation within Cape Town.

150 L

Thermosyphon Close-Coupled

Geyser and collectors installed together on the roof. Natural circulation — no circulation pump required.

200 L

Thermosyphon Close-Coupled

Same natural-circulation design with larger storage — suited to families with higher hot water demand.

150 L

Flat-Roof Thermosyphon

R23,500 – R25,000

Mounting structure positions the collector at the correct height for natural circulation on flat roofs.

200 L

Flat-Roof Thermosyphon

R26,000 – R28,000

Natural circulation with 200-litre storage for larger families on flat-roof properties.

150 L

Flat-Roof Pump System

R25,000 – R29,000

Circulation pump moves water between collector and geyser — for flat-roof layouts where a pump is preferred.

200 L

Pumped circulation with 200-litre storage for larger households on flat-roof properties.

150 L

In-Roof Pump Split

Collector on the roof, geyser concealed inside the roof space, connected via circulation pump. Neat, hidden installation.

200 L

In-Roof Pump Split

R31,400 – R34,000

Split installation with concealed 200-litre tank — suits higher-demand households wanting a tidier roofline.

Lowest price
Retrofit

Use Your Existing Geyser

Common questions

Pricing FAQs

Are these solar geyser prices final?

No. The prices shown are indicative ranges. Final pricing depends on the system configuration, roof type, installation requirements, pipe runs, electrical work and site conditions. We confirm an exact quote after a free on-site assessment.

What is the cheapest solar geyser option?

The solar retrofit — using your existing geyser — is our lowest-cost option, from R18,700. It is only suitable if the existing tank is in good condition and compatible with the proposed solar collector and circulation system.

What's the difference between close-coupled, flat-roof and split solar systems?

Close-coupled systems place the geyser and collector together on the roof and use natural thermosyphon circulation. Flat-roof systems mount the same components on a suitable frame for low-pitched roofs. Split systems place the collector on the roof and the geyser inside the roof space, using a circulation pump.

Do I need a 150L or 200L solar geyser?

As a rough guide, a 150L system suits 1–3 people and a 200L system suits 3–5 people, but household habits, bathrooms and peak usage matter. We recommend the right capacity during the assessment.

Do the prices include installation?

Yes — the ranges shown include supply and standard installation within Cape Town. Additional work (structural reinforcement, extended pipe runs, extra electrical) is quoted separately if the assessment finds it's required.
