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.

Appeal Court Judge delivers inaugural lecture at the UFS
2009-09-16

 
Judge of Appeal, Belinda (BJ) van Heerden an expert on child and family law, recently delivered her inaugural lecture as Professor Extraordinary in the Department of Criminal and Medical Law in the Faculty of Law at the University of the Free State (UFS). With the topic Chicken soup Jurisprudence: Implementing children’s rights in South Africa she focused, amongst others, on the history of the implementation of children’s rights in South Africa. The picture of today is a whole lot different than that of twenty years ago. “We have invested in our children, we have begun to treat them as worthy citizens,” she said. According to her, children’s rights is one of the best success stories of our South African democracy so far. At the occasion were, from the left, front: Prof. Hennie Oosthuizen, Head of the Department of Criminal and Medical Law at the UFS; back: Judge Van Heerden, Prof. Driekie Hay, Vice Rector: Academic Planning at the UFS; and Dr Neels Swanepoel of the Department of Law of Procedure and Law of Evidence at the UFS.
