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.

Some of Africa’s top young minds gathered at the University of the Free State to discuss new ways of thinking about education on the continent.

About 50 current and past recipients of the prestigious Mandela Rhodes Scholarship from across the continent gathered on the Bloemfontein Campus to attend the Community of Mandela Rhodes Scholars Summit from 29 September to 1 October 2012. The theme for the summit was Re-Imagining Education in Africa and recipients from South Africa, Kenya, Nigeria and Uganda attended.

Prof. Jonathan Jansen, Vice-Chancellor and Rector of the university, addressed the Mandela Rhodes scholars and told them as Africa’s next generation of leaders they have to be courageous, caring and agents of change. “You cannot re-imagine education unless you have imaginative leaders”, he told them. Referring to leaders like Martin Luther King, Chief Albert Luthuli, Ghandi and Nelson Mandela, Prof. Jansen told them in order to lead, they should have the capacity for caring, contemplation, courage, change,contrition,conciliation and clarity.

Mandela Rhodes Scholar and Convener of the Summit, Andrew Gasnolar, said the insights gained will be utilised by recipients in their spaces. "A consistent element which cropped up was that our privilege requires us to do the right thing. Active citizenry is required in which we all actively take a part in the education situation - from adopting a student to adopting a school to taking up teaching."
