[rev_slider_vc alias=”Solarent”]


Solarent was launched in January 2010 specifically to sell solar water heating systems into the residential and commercial markets on a “rent-to-own” basis and is recognised as one of SA’s pioneers pursuing making solar affordable through financing. Today the company has installed over 1500 systems. In 2013 Solarent was appointed as a certified supplier to the City of Cape Town’s solar water heating program.

During 2014 the company launched its new and innovative solar water heating solution – Heatbox. Designed by the team in collaboration with a leading manufacturer, Heatbox is 35% cheaper than its nearest competitor and has an efficiency rating comparable with the high end systems.   Sales to date have exceeded expectations and prospects for capturing the lion’s share of the market look very favourable. Heatbox is SABS and Eskom approved.

The system is exclusive to Solarent, however market demand has forced the company to consider bulk supply to other distributors and negotiations are underway which could see as many as 20,000 systems being supplied under an OEM basis nationally.
