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.

Department Old Testament receives visiting professor from the USA
2009-05-19

Prof. Arie Leder, professor in Old Testament at the Calvin Theological Seminary, Grand Rapids, Michigan in the United States of America (USA) set foot on the African continent for the first time when he visited Prof. Fanie Snyman of the Department Old Testament in the Faculty of Theology at the University of the Free State (UFS). Prof. Leder is a visiting professor at the Department of Old Testament.

During his two-week-long visit to the faculty he amongst others lectured to undergraduate and master’s students. The lectures addressed issues related to the first five books of the Old Testament with the focus on the interpretation of the Hebrew text. The mentioned historical books of the Old Testament were discussed with the postgraduate students of the faculty. During the meeting of the Discussion Group for Biblical Sciences, Prof. Leder presented a public lecture with the theme, “Lady Wisdom and Sir Folly: Preaching Esther for such a time as this”.

According to Prof. Snyman, the agreement with Prof. Leder was to present the same lectures as what he would have delivered at the Calvin Theological Seminary. “The aim was to compare the standards, course content and presentations of the lectures that are presented by the respective departments, with each other. We compare well with the Calvin Theological Seminary and we do not have to be ashamed of ourselves. The feedback of the students about the exposure to another lecturer from another institution was also positive,” said Prof. Snyman.

The possibility of future collaboration was also discussed, specifically with the objective of both institutions publishing articles in the respective journals of both institutions. A further positive result of Prof. Leder’s visit is that colleagues of the Calvin Theological Seminary will be approached to act as external examiners for postgraduate students,” said Prof. Snyman.

The Calvin Theological Seminary libraries are some of the best equipped theological libraries in the world and as a result of the collaboration between our two institutions, staff of this faculty will get the opportunity to visit the Calvin Institution and to utilise the facility.
