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.

A real indaba it was
2010-09-07

No expert panels! No rubrics! Only a fair measure of healthy anxiety that goes with public speaking!

These features describe the meeting that staff members from the Faculty of Education recently had at Indaba Lodge on the banks of the Modder River. The purpose of this get-together was to create a time and space where staff members could not only celebrate their own research efforts, but also acknowledge, support and validate one another’s work.

The day kicked off with the dean’s research vision for the faculty. Thereafter seven staff members doing their Ph.D.s were introduced. Their presentations were followed by inputs from the guest speaker, Prof. Rob Pattman from the University of KwaZulu-Natal (UKZN). He congratulated the presenters on their cutting-edge research, their eloquence and the manner in which they managed to communicate complex matters in simple ways. Ideas he shared from his own research on social identities and critical agency (with a focus on gender and race) served to affirm the relevance of the topics presented by the Ph.D. candidates in transforming the education system as well as the South African society as a whole.

A festive lunch, in honour of retiring Prof. Johan van Staden, brought an affective dimension to the Indaba in the form of heart-felt goodbye messages from colleagues who had shared his academic life for more than 20 years.

After lunch five master’s students had the opportunity to share their research in the form of poster presentations. A lively interest among participants and critical, but constructive questions characterised this session. A potpourri session followed, comprising work in progress, completed surveys, research awards and innovative research methods.

The wrap-up by Prof. Dennis in no uncertain terms affirmed that researchers in the Faculty of Education not only crossed the Modder River, but also the proverbial Rubicon on 21 August. It was envisaged that henceforth:
- Supervision will take on a collaborative character.
- Soon a research forum for Ph.D. students and their supervisors will be established where these students and supervisors can start practising their agency.
- Instead of relying on outside experts who come and “tell” faculty staff members what to do, insiders should start building their own vibrant research-based practices by forming reading groups to discuss seminal works (e.g. Foucault and Freire) and research methodologies (e.g. Burke’s Pentad).

The Indaba was aptly concluded by one of the participants who, on behalf of all attendees, thanked and congratulated the dean on the initiative to give impetus to research. Analogous to the 2010 slogan, Feel it, it is here!, he said: “I feel so inspired and empowered, I can almost taste it!”
