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.

Inaugural lecture: Prof Pieter Verster
2005-02-16

Prof Pieter Verster from the Department of Missiology at the University of the Free State (UFS) will deliver his inaugural lecture on Wednesday 23 February 2005 at 19:00 in the CR Swart Auditorium on campus.

The topic of the lecture is Die begronding van die sending by Paulus in die lig van sy erkenning van die godheid van Christus.

Pieter Verster started his theological training in 1973 at the UFS and continued it at the University of Pretoria (UP). He obtained the degrees BA (cl) from the UFS in 1976; BA Hons (Greek cl) from the UP in 1979; MA (Greek) from the UFS in 2000;

a BD (cl) from the UP in 1979; a Post-graduate Diploma in Theology (cl) from the UP in 1980; a DD (Missiology and Religion Studies) from the UP in 1985 and a DD (Dogmatics and Ethics) from the UP in 1989.

He was honoured for academic excellence (UFS 1975), overall excellence (UP 1979) and research excellence (UFS 2004). He has visited various overseas universities and institutions in the Netherlands , Switzerland , Germany and the USA ,.

Prof Verster has also published various articles in academic journals and his books include Wie het die waarheid beet? for which he received the CUM/RSG writers’ competition prize in 1996. He has also published short stories in Tydskrif vir Letterkunde and Dolos and poems in inter alia Literator and Litnet.
