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.

Mr Rantooa Moji has recently joined the UFS Council by virtue of being chairperson of the university’s Institutional Forum (IF).  The IF’s function is to advise Council in accordance with the Higher Education Act and UFS Statute.
 
Born and bred in Qwaqwa, Mr Moji is a junior lecturer in Chemistry at the university.  He completed his BSc (Hons) in Chemistry at the then UNIN (Qwaqwa), which is now part of the UFS.  He also completed an MA (HES) at the University of the Free State.
 
Fascinated with Chemistry
“I pursued science mainly due to my school background, but I also have a keen interest in the subject.  The diverse applications of Chemistry in daily life have always fascinated me and that is why I chose to pursue it,” he says.
 
During his postgraduate studies at the UFS, Moji was exposed to education and management trends in higher education.  He has subsequently become involved with labour relations issues through the personnel union Nehawu.  He says he has a passion for the welfare of workers and therefore fulfils a number of roles in the union, including representing members in disciplinary and grievance hearings, being part of the negotiations team, and representing the union on a number of institutional committees, such as the Health Care Committee.
 
Passion for worker’s welfare
Says Mr Moji: “I feel that my experience as an academic and a union activist puts me in good stead to ensure that the views and aspirations of employees are taken into account in the Council’s deliberations and decision-making.”
 
Mr Moji is married, with two daughters and one son.
