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.

The practice of mourning loss

Among international delegates from over 60 nations and more than 1 300 participants, Dr Jennifer Githaiga presented her paper on the practice of mourning – the African way.

Her paper questioned the language used in psychology to ‘pathologise’ African people’s mourning practices. Drawing from her doctoral research, she explained the role of maintaining close bonds with family members after they pass away. Rather than severing these bonds, Dr Githaiga argued that continued attachment beyond death plays a significant role in healing the trauma of loss.

Dr Githaiga’s entitled her paper ‘The “pathology” of post-bereavement bonds: cultural positioning in qualitative inquiry.’ She presented this at the Tenth International Congress of Qualitative Inquiry (ICQI). A conference that has become one of the most important events on the calendar of qualitative researchers across the globe. The event was hosted at the University of Illinois in Urbana-Champaign from 21 - 24 May 2014. The theme of the conference this year was ‘Qualitative Inquiry and the Politics of Research’.

Dr Githaiga is currently a postdoctoral fellow at Trauma, Forgiveness and Reconciliation Studies at the UFS. During the congress, she also found herself in the role as ambassador to Kovsies. Not only did she rub shoulders with highly-regarded Profs Kenneth and Mary Gergen, but also spoke with leading scholars in the field of qualitative research interested in our university.
