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.

Our Abe Bailey scholars are packing for the UK

Academic excellence and strong leadership has become synonymous with our university, as our two Rhodes scholars for 2011, and the recent announcement of our two Abe Bailey scholars from the UFS have shown.

Nida Jooste and Ryan Lamb are two of the proud recipients of Abe Bailey Travel Bursaries and will be heading off to the United Kingdom on 26 August 2011, to visit several universities in England and Scotland. These two were chosen from hundreds of UFS applicants and will join Abe Bailey bursary holders from the rest of the country.

Both students are academic achievers, but also excel in other fields. This is what set them apart from the rest of the applicants for the bursaries.

Ryan (23), a Medical Physics honours student at our Faculty of Health Sciences, received the Senate Medal for the best bachelor’s degree student at the UFS. He was one of a hundred students at the Brightest Young Minds Summit this year and was one of the 2008 delegates to the World Youth Forum, hosted by the International Association for Poetry and Solidarity in Italy.

This young man is the founder of a group called Poets Anonymous, which provides a platform where poets, artists and dancers in Bloemfontein can express themselves.

Nida (21) is a very familiar face on our Bloemfontein Campus, as she served as the Deputy Chairperson of the Interim Student Council for the past year.

This fourth-year LL.B. student says she has known about the Abe Bailey bursary since her first year, but had to wait to apply, since the scholarship is only open to final-year students and junior lecturers. She applied last year, but did not even make it to the short list for candidates.

“I realise now that I was not involved enough then. Luckily I became much more involved in campus activities during the past year and also improved my academic performance greatly,” she says.

Nida and Ryan both hope to use the opportunity to learn new approaches to solving problems. Ryan says he is looking forward to the opportunity to network with other bursary holders and to share experiences with them, before returning to the UFS to implement what he had learned.

Nida says she also hopes to see how universities in First-World Countries operate, in order to apply that knowledge when she returns to the UFS.
