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.

“Change is facilitated through education, not by means of radicalism, violence, or revolution.” Speaking at the Bloemfontein Campus of the University of the Free State (UFS) on Thursday 12 May 2016, the German Ambassador, Walter Lindner, urged students to engage in profitable dialogue instead, keeping their values and ideals in mind while changing the system from the inside.

The Institute for Reconciliation and Social Justice (IRSJ) hosted a full day of dialogues and discussions, the highlight of which was a critical dialogue with Ambassador Lindner, entitled “Universities as agents of transformation in society—Germany’s experience with the student protests of the 1968 movement and the difficulties it has reconciling with its past.” This was followed by a student colloquium, hosted by the Student Representative Council, which concluded with the second in the Africa’s Many Liberations seminar series, co-hosted by the IRSJ and the International Studies Group (ISG), with the title of “Fanon and the relevance of personal and collective decolonisation in today’s South Africa”.

Mr Lindner related his experience of student protests in Germany during the late 1960s, drawing certain parallels with South Africa’s own recent protests. According to Ambassador Lindner, it is “the impatient youth that drives forward change”, but cautioned against radicalism as a long-term solution.

Pointing out the various challenges facing humankind today, such as the lack of natural resources, unbridled climate change, and population growth, Mr Lindner stated that politicians (and the youth of today) would do well to focus on these greater issues, rather than focusing on the more mundane issues with which they are faced on a day-to-day basis.

The subsequent dialogue session was facilitated by Tali Nates, Director of the Johannesburg Holocaust and Genocide Centre. A diverse array of questions and comments, both radical and more conservative, was directed at the ambassador, which he handled with unflappable aplomb.
