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.

Prestige Scholars Programme invests in promising academics

Whilst many academics find it challenging to have sustainable funding for specific projects, it is often just as challenging to find relevant exposure and good mentorship programmes to fully prepare academics toward becoming full professors.

Prof Jonathan Jansen, Vice-Chancellor and Rector of the UFS, designed the Vice-Chancellor’s Prestige Scholars Programme (PSP) specifically targeting newly-completed post-doctoral students who are already members of the academic staff.

The goal is to select the most promising young scholars and to make substantial institutional investment in their development.

To date, the PSP has produced 2 Fulbright scholars; 10 National Research Foundation (NRF) rated scholars; 1 NRF Blue Skies research project and 14 NRF Thuthuka-funded projects. These scholars work with the best academics at leading universities on three continents.

Prof Jackie du Toit, co-director of the programme, explains that while the PSP does not provide funding, it is a great programme to empower scholars by means of assistance towards generating funding from outside sources.

Prof Du Toit co-directs this programme with Proff Corli Witthuhn, Vice-Rector: Research and Niel Roos from the Department of Africa Studies.

“The PSP bases its approach to funding on the philosophy that young scholars are to be encouraged towards financial independence, based on a viable postdoctoral project that would sustain their scholarship for five to eight years post PhD. We believe that the cachet and long-term sustainability of existing funding programmes such as Fulbright outweighs the short-term benefits of automatic funding from the PSP. We also endeavour to teach young scholars to work cleverly within institutional parameters, rather than leave them floundering once they step off the active PSP.”
