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.

Vishuis’s fourth Varsity Cup victory about more than rugby

For Vishuis, it is about more than just rugby.

This is what Henco Posthumus, captain of House Abraham Fischer’s rugby team, had to say after his team was crowned the national Varsity Cup champions for an incredible fourth time. According to the flyhalf, the title of the leading residence team in the country is “special for the guys”.

Vishuis is the most successful residence team in the history of the tournament. Apart from their four titles, they have played in a total of five Varsity Cup finals.

On 11 April 2016, the residence from the University of the Free State (UFS) launched a great comeback in Stellenbosch to beat Patria (Pukke) by 37-29. This victory ensured that Vishuis was unbeaten in 2016.

Great fighting spirit


The Kovsies started off well against Patria, but were behind 16-29 shortly after break, and had to “delve deep”, according to Posthumus. “To be behind in this way is not what one would prefer. For some reason, we have been in similar situations before, and we know how to make a comeback,” he said.

“We looked one another in the eye and decided that we are not going to lose again in the final.” In last year’s final in Bloemfontein, when Posthumus played at fullback, Vishuis got stuck against Mopanie (Tuks) at the end of the match, and they wanted to prevent this from happening again.

Heymans a hero


According to the Vishuis captain, one of his team’s assistant coaches, Franco (Vaatjie) van der Merwe, spoke harshly to the players when they were behind. The victory was clinched in the dying moments, with the second try of scrumhalf, Ruben Heymans, when the score was 29 points each. Heymans was a star, and the well-deserved Man of the Match.

Posthumus said it is a great privilege to carry the title of Varsity Cup champions. His team has worked hard to reach the top.
