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 becomes Varsity Netball champions – again

Kovsies has become the first team to successfully defend the Varstiy Netball title when they beat Tuks 49-42 in the 2014 final in Pretoria on Monday 20 October.

University of Pretoria (Tuks) might have been unbeaten for the entire 2014 tournament, but this did not hinder Kovsies in becoming the Varsity Netball champions for a second consecutive time.

From the outset, both these furiously focused teams fought hard and only after ample turnovers could Kovsies finally manage to open the score board.

The Mostert sisters, Karla and Tanya, won a couple of crucial balls, leaving the UFS dominating possession in the opening exchanges.

When Tuks eventually got to scoring, they could not stop the UFS from rushing to a 9-3 lead after the first ten minutes. The visitors had established a 13-5 advantage by the first break, keeping the Pretoria crowd quiet.

The home side came back shooting in the second quarter with great determination, fighting their way back into the game. Tuks ran hard, needing to work hard against Kovsies, who still managed to be in the lead with 22-16 at half-time.

Kovsies made good use of their power play early in the third quarter to stretch their lead further to 30-22. They made the most of their opportunities, going into the final quarter with a 39-31 upper hand.

Even though Tuks made a couple of changes during the final break, they could not avoid defeat in the end.

Kovsies’ Lauren-Lee Christians was also the player of the match, while the champion’s captain, Karla Mostert, was announced as the Player of the Tournament.

This hard-working defender made a number of crucial interventions alongside her sister Tanya in the final. Karla proved that she was the fans’ tournament favorite, claiming the most votes and winning a Samsung S4.
