Choosing the right solar geyser isn’t only about the sticker price — it’s about long-term performance, reliability, and support. SunScan specifies and installs high-pressure Solar Geysers sized to your household and roof conditions, using proven components and accredited installers across the Western Cape. 
 
Whether you prefer a compact, roof-mounted thermosiphon like SunSyphon, a split-system with a discreet tank and robust flat-plate collector like SunSaver, or our premium evacuated-tube option SunSeeker for cooler or coastal microclimates, we’ll guide you to the best fit. Pricing depends mainly on tank size (typically 100–300 L for most homes), collector type, roof pitch and covering, pipe runs, and whether a Full pumped system retrofit kit is required. 
 
Every installer will quote clearly showing what’s included — hardware, valves, lagging, labour, and compliance items — so there are no surprises on install day. During a short site survey, installers confirm sun exposure, shading, and existing plumbing, and will advise on the most economical way to integrate with your current cylinder or replace it if it’s near end-of-life. We also size with real-world usage in mind: families who run a dishwasher and washing machine daily, or enjoy longer showers, may benefit from stepping up one tank size for comfortable reserves in winter. 
 
All SunScan systems are installed to South African standards by our accredited network and are backed by manufacturer warranties and after-sales support you can reach.

Frequently Asked Questions

A solar geyser uses solar panels (collectors) to absorb sunlight and convert it into heat. This heat is transferred to water stored in an insulated tank, providing hot water for household use.

Yes, but their efficiency may be reduced. Most solar geysers have an electric backup system to ensure a continuous hot water supply when sunlight is insufficient.

Yes. The system heats water during the day and stores it in an insulated tank, which keeps it hot for use at night or early in the morning.

A well-maintained solar geyser can last 15 to 20 years. Regular servicing and proper installation can extend its lifespan.

The periodic maintenance includes:

  • Cleaning the solar panels to remove dirt and debris
  • Checking for leaks or blockages in pipes
  • Flushing the system periodically to remove sediment buildup
  • Ensuring the backup system functions properly
