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.

He is excited about the young minds he saw and interacted with at the graduation ceremony of the University of the Free State (UFS). This is what Max du Preez, one of South Africa’s leading journalists and political analysts, said after receiving an honorary doctorate.

According to Du Preez (Humanities), he was inspired by the Winter Graduation ceremony on 30 June 2016 in the Callie Human Centre on the Bloemfontein Campus. He is happy to finally also call the UFS his alma mater. He grew up in Kroonstad and is a true Free Stater, but previously graduated at the Stellenbosch University.

The UFS awarded four honorary doctorates – the others to Prof Joel Samoff (Humanities), Trevor Manuel and Dr Reuel Jethro Khoza (both Economic and Management Sciences) – and two Chancellor’s medals at the morning ceremony on 30 June 2016. Chancellor’s medals were awarded to Antony Osler and Marguerite van der Merwe (née Osler).

Manuel impressed by amount of soul

At the Chancellor’s Dinner, which was held in the Centenary Complex on the Bloemfontein Campus on 30 June 2016, Du Preez said he feels honoured. He said South Africans must embrace the diversity of the country, and the UFS is a good example. “If the University of the Free State can make it, South Africa can make it.”

Manuel, a former South African Finance Minister, said he is honoured by the amount of soul he experienced from Dr Khotso Mokhele, UFS Chancellor, and Prof Jonathan Jansen, Vice-Chancellor and Rector of the UFS. “We cannot tolerate what is wrong (in the country) and need to push the boundaries of what is right,” he said.

UFS stands out regarding understanding


Dr Khoza, a distinguished thinker and businessman, also thanked the UFS at the Chancellor’s Dinner. “We shall strive to be known less for what we say, but rather more for what we do,” he said about the country.
According to Prof Samoff, Professor in Africa Studies at Stanford University (USA), “South Africa has committed itself to building a democratic, non-racist, and non-sexist society”. “Where the University of the Free State stands out, is in its understanding that societal change – ‘transformation’, to use the current terminology – is not an outcome, but a process. A difficult process.”
