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.

Although Prof Jaap Steyn will be honoured officially for his contribution to Afrikaans as an academic language at the end of this month, he only became aware of his nomination after he had won the award.

According to this research fellow in the Department of Afrikaans and Dutch, German and French at the University of the Free State (UFS), he is grateful for the recognition. He has recently been awarded the Jan H Marais Prize for his outstanding contribution to Afrikaans.

Former Kovsie honoured together with Prof Jan van der Watt
According to a statement by the South African Academy for Science and Arts, the award was jointly made to Prof Steyn, who is probably the best-known South African language historian, and Prof Jan van der Watt van Nijmegen from the Netherlands. The prize money of R500 000, which they will share, will be presented in Stellenbosch on 30 May 2017.

Prof Steyn is a former Kovsie, who was a research professor at the UFS from 1985 to 1997, and at the age of 78 is still a research fellow. “After the announcement of the prize, I learnt that I was nominated by two of my colleagues,” he says.

His most difficult work was probably also his best
Over the past 50 years several of his publications, biographies, and books have seen the light. He believes that nothing one does is perfect. His most difficult work was the biography of NP van Wyk Louw. “It was probably also my best work,” he says. “The book I enjoyed working on most, was the biography of the author MER, or ME Rothmann.”

Prof Steyn has also received awards such as the Stals Prize, the Louis Hiemstra Prize, the NP van Wyk Louw medal, and honorary membership from the South African Academy for Science and Arts.

He says the staff in the Department of Afrikaans and Dutch, German and French are very friendly and helpful to still render him assistance as a research fellow.
