The Microcare solar geyser controller uses PV panels to heat the water instead of EV tube or flat plate technology. The advantage is that no plumbing is needed. Connect up to your existing geyser and start saving money from day one.
The controller costs R8900 and you just add your own panels. Alternatively you can buy the kit which includes 3 x 275W HV Panels, Controller, Wi-Fi & Thermistor for R18900.
