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.

Kovsies shine at USSA Cross Country Championships

Kovsie cross-country athletes Boy Soke and Thandi Malindi were included in the USSA squad for 2010 at the World Student Cross-Country Championships in Canada. The final team will be announced after the SA Cross-Country Championships. They recently participated in the USSA Cross-Country Championships that were held at the University of Johannesburg. According to Mr DB Prinsloo from KovsieSport at the University of the Free State, the UFS team did extremely well at the recent USSA Cross-Country Championships.

Kovsies won the women long-race team competition (8 km), while the men came second in the men’s long-race team (10 km) competition. In the short-race team competitions (4 km for men and women) the UFS men finished fourth and women ended in fifth place respectively.

Thandi Malindi, the UFS Women Cross-Country captain, was the first Kovsie over the line (third place), followed by Nelmarie Loubser (4th) and Maryna Swanepoel (6th), who also won the team competition in the 8 km (long race) with 13 penalty points against the 14 penalty points of the Maties who finished second.

Mr DB Prinsloo from KovsieSport at the UFS praised the Kovsie athletes for the manner in which they ran the race. “Thandi gave her all; so much so that she had to be admitted to hospital due to dehydration. Nelmaré ran the hills with a smile on her face and Maryna, who suffered from low blood sugar, persevered until the end so that a Matie athlete could not pass her. You all showed to us what ‘vasbyt’ really means,” Mr Prinsloo said.

Kovsies performed above expectation in the short race (4 km) for women. “Our women finished fifth in the team competition. If one takes into consideration that the Kovsies were represented by 400/800 athletes, i.e. Elri Richter (400/800), who came seventh, Anneri Ebersohn (400/400 hurdles), who ended in sixteenth place and Yvonne Eyssen (heptathlon) who ended in twentieth place, it makes this performance even better,” Mr Prinsloo commented.

In the men’s short race (4 km) where the Kovsies were represented by young first-year 800 m athletes, the UFS did excellently by finishing in fourth place. Hanne Naudé (18th), Lebohang Mpure (19th), Abri Horak (26th) and Gerrit Viljoen (34st) ran their hearts out!

The long race (10 km) for men, which was run on an extremely difficult course, was another highlight – also for the Kovsies. The Kovsies finished second in the team competition. Boy Soke (4th), Windy Jonas (8th), Schadrach Mochelenyane (10th) en Michael Tlhoro (21st) represented the Kovsies with honours. Unfortunately Johan Cronjé and Dumisane Hlaselo had to withdraw from the race due to injuries.
