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.

Rolene Strauss, Stefan Janse van Rensburg and Shimla’s Young Guns team awarded certificates of excellence by Dean: Student Affairs.

On her ninth day as Miss South Africa, Rolene Strauss, a fourth-year medical student at the UFS, together with Stefan Janse van Rensburg, captain of the Shimla’s Young Guns who won the U/20 Varsity Cup title, addressed a group of male students.

Residents of the JBM men’s residence, as well as the Shimla Young Guns, were inspired and motivated by Rolene and Stefan.

“Kovsies is where I come from; this is why I am who I am today. One day I will call my autobiography, Life as a garden, because I see life as a big garden where we all grow as flowers. In the Kovsie garden we are flowers with our roots firmly anchored in Kovsie soil.

“I take from Kovsies the ability to adapt, to appreciate and to care. With these positive characteristics, people around me experience freedom, love and kindness,” Rolene said.

Stefan told the group of students that it is important to surround yourself with people who can lift you up, especially in difficult times.

Rudi Buys, Dean: Student Affairs at the UFS, presented Rolene, Stefan and the entire Young Guns team, together with their coach, Jaco Swanepoel, certificates in recognition of excellence.
