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.

UFS athlete Wayde van Niekerk proved himself as a world-class contender yet again. He grabbed silver in the 400 m sprint at the 2014 Commonwealth Games in Glasgow on Wednesday 30 July 2014.

Van Niekerk, who achieved a time of 44.68 sec in this race, took the lead at the first bend and held onto this position through the back straight before Kirani James of Granada pulled away over the final 150 m.

Lalonde Gordon of Trinidad and Tobago came third with a time of 44.78 sec.

This Commonwealth silver medal sees the Bloemfontein athlete’s magnificent year come full circle. Earlier this year, Van Niekerk broke the 15-year-old national record at the Diamond League meeting in New York with a time of 44.38 seconds.

Another star from the Free State, former Kovsie Kate Roberts, who took part in the mixed triathlon relay at the Commonwealth, also pocketed a silver medal. Her team mates were Richard Murray, Henri Schoeman and Gillian Sanders.

In addition, Neil Powell – Shimla Rugby alumnus from 2001 – played a central part in obtaining a gold medal at the Commonwealth Games. Powell is the coach of the Springbok 7s team that placed first at the Games in July 2014. 
 
On a more local level, Kovsie alumnus and SA athlete, Johan Cronje, was nominated for the Sportsperson of the Year. You can vote for him by sending ‘SPORT 4’ via sms to 43043.
