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.

Student organisation tackles difficult questions in debate

“South Africa is consumed by a monster, namely the lack of critical thinking and dialogue with regard to our problems. Now is the time to make radical changes.” This is according to Nombuso Ndlovu, who spoke at the first debate in a series of Commercio and the UFS Business School.

“Young people are more interested in social gatherings than applying their minds to the problems of South Africa,” she said. Nombuso is the CEO of Commercio.

Commercio is the student organisation in the Faculty of Economic and Management Sciences. Two teams, one positive and one negative, debated the topic: Is South Africa’s current economic direction viable?

What emerged from the debate was that our students are well-aware of what is going on in our economy and that people cannot just sit back and expect government to deliver. Every individual has a responsibility. South Africa has a “democratic deficit” society, a “corruption-stricken economy” and “economic activism” is necessary to get the economy on the right path.

Prof. JP Landman, Visiting Professor at the Business School, economic advisor, analyst, columnist and also managing director of the Aardklop Arts Festival, was the expert panel member. He said the critical issue in South Africa is “how do you distribute wealth while keeping things going?”

“It is fantastic that South Africans have developed a collective repulsiveness for corruption.” People must know what underpins society and where aggression comes from.
