Ostrich leather tannery's cost and energy savings quantified after two-and-a-half years of operation with solar

Cape Karoo International (CKI), is the result of a merger between Klein Karoo International and Mosstrich, and is the world’s leading producer of ostrich leather, feathers & meat products with our tannery division boasting an 80% global market share in its supply of ostrich leather. Despite this prestige, our responsibility towards sustainability remains. In fact, ever more so. With our dependence on fossil fuels ever increasing, we decided to seek opportunities for improving on the energy security of our business.

Solar cooking with evacuated tubes

Evacuated glass tubes are central to a host of solar thermal applications. Several years ago innovators began harnessing evacuated glass tubes for cooking, putting them in a horizontal orientation and adding a reflective concentrator wing on each side, and then using an oblong narrow cooking tray that slides inside the tube. Various tube manufacturers have responded to this innovation and now offer much larger evacuated glass tubes designed expressly for solar cooking.

Centurion Building: Lessons and savings from solar thermal in the residential sector

A report on one of SOLTRAIN's demonstration projects in the residential sector in Cape Town has been published.

The Centurion Building's solar thermal system (shown below) with heat pump backup was commissioned in 2018 and has saved 470MWh of electricity (a reduction of 69%) and R220,000 since commissioning.

The building is an old hotel that has been re-purposed as apartments for retirees. There are 134 apartments, with some retail outlets on the ground level.

SOLTRAIN Funded Solar Hybrid Project

In 2020, SOLTRAIN awarded bursaries to qualifying research students in its five partner countries. One of the recipients was Kago Rabasoma from University of Botswana.  His project involves fabricating a working model of a solar absorber and nocturnal radiator hybrid system (“SAANR”). The system is intended to harness solar energy during the day to produce hot water and then use nocturnal radiation to produce cool water. The hot water can then be used in the evenings for domestic purposes such as washing and bathing, and then the cool water can be used during the day. The main supervisor of this work is Dr Kevin Nwaigwe with co-assistance from Dr Ditiro Setlhaolo.
