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.

From disregard to acknowledgment - the role of the Griekwas in South Africa
2006-03-09

The University of the Free Sate (UFS) is working in conjunction with the Griekwa nation on an initiative titled: From disregard to acknowledgment - the role of the Griekwas in South Africa.

The Griekwa National Conference (GNC) requested that research be conducted in conjunction with the UFS on various aspects linked to the Griekwa language, -culture, -history, - leadership, their role in the South African community (past and present) and the conservation of their historical cultural heritages. Four possible research focus areas  have been established, namely a documentary film, the Adam Kok house, ethno historical research and reading material for Griekwa leaders.

A historical meeting took place yesterday at the UFS where the Supreme Chief of the Griekwa nation was present. From left are Prof Frederick Fourie (Rector and Vice-Chancellor of the UFS), Chief Cecil le Fleur, (chairperson of the chiefs council of the GNC), Supreme Chief Alan Andrew le Fleur I, Rev Kiepie Jaftha (Chief Director: Community Service) and Prof Piet Erasmus (Department of Anthropology at the UFS).
