Solar Panels at UFS Qwaqwa Campus
Revolutionising electricity with sun power: Solar panels at the Qwaqwa Campus.
Over the past few years the University of the Free State (UFS) has been planting panels, now the time has come to reap. Solar farms produced a return on investment in the form of R1.4 million in savings as a result of photovoltaics (PV) between January and March 2019. Nicolaas Esterhuysen, an electrical engineer at the Department of University Estates also reported a 2.34% decline in electricity usage between 2013 and 2018. 

Solar panels are the future 

According to Esterhuysen, the solution to a power crisis lies in “either becoming more energy efficient or generating our own at a cheaper cost”. All campuses have managed to save a total of R5.4 million in 2018 through producing our own power (solar PV) and actively managing the instantaneous load demand with building management system (BMS) software.

Overall, ground-mounted PV installations at all campuses contribute 2609 kilowattpeak (kWp) under standard conditions. The Bloemfontein Campus accounts for 979kWp of that amount while the South Campus generates 762kWp, with the Qwaqwa Campus producing 748kWp, and the Paradys experimental farm bringing in 120kWp to the grand total (to be commissioned June 2019).

Rooftop PVs generate electricity through the 80kWp Muller Potgieter Building, the 255kWp Bloemfontein Campus computer lab, the 35kWp Qwaqwa Campus computer lab, 135kWp Qwaqwa Campus Mandela Hall, and 416kWp Thakaneng Bridge panels. This is a total of 921kWp. 

Winter is coming with tariff terrors 

A 15.63% electricity tariff increase is projected this year in light of the annual winter adjustments commissioned by Eskom and Centlec. To gear up for the associated spike in power use over this season, University Estates advises the Kovsie community to use energy efficiently. “Think twice before switching on the heating and make sure to switch it off when you leave the office,” advises Esterhuysen.

In addition to generating electricity, saving initiatives such as implementing light-emitting diode (LED) lighting with motion sensors and actively managing demand at peak times have been implemented.

What’s next?

The next step is to rethink dated mechanical installations that are used to heat some of our older buildings. Replacing similar installations across all of the campuses are some of the ways the university intends to escalate energy efficient in future.

Africa’s lost voice during the Second World War echoes throughout book

If you pick up any historical record on the Second World War, you would see that, to a large extent, Africa has been missing from the history pages until now.

Africa and the Second World War (WW II) is a book edited by Prof Carolyn Brown from Rutgers University and Prof Judith Byfield from Cornell University in the United States. The book is the outcome of various papers presented during a workshop at Rutgers University and at a conference on WWII hosted at Cornell University.

The co-editors of the book were invited by Prof Jonathan Jansen, Vice-Chancellor and Rector of the University of the Free State (UFS), to launch the book at the UFS. The Centre for Africa Studies at the university, in collaboration with the UFS Sasol Library, presented the launch on Tuesday 16 August 2016.

Bestowing honour upon Africa’s role during WW II
Many people do not know that WW II started in Ethiopia with the Italian Invasion. This is generally omitted from discussions or complete histories of WW II. The present book explores the experiences of male and female combatants, peasant producers, women traders, missionaries, and sex workers during the war. “Many people are not aware that Africa produced most of the mineral and agricultural during the war,” said Prof Brown.

Book to reach a greater audience for discussion
The co-editors hope that the book reaches people who teach WW II history, as many talk about only the nationalist movements. “The opening of the book also talks about the importance of South Africa during WW II,” said Prof Byfield. The authors hope that people will read the book to start thinking comparatively about the war.
