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.

The UFS produces some of the finest teachers in the country
2015-03-02

 

The quest for producing well-grounded, excellent and prolific teachers at the UFS is bearing fruit. Numerous accolades have over the years been bestowed on some of the UFS Qwaqwa Campus's finest graduates.

"For us as the faculty, it is gratifying and rewarding to learn about the achievements of our students. These achievements do not only validate our efforts, but inspire us as well,” says Dr Dipane Hlalele, Assistant Dean in the Faculty of Education at the UFS.

Dr Hlalele also revealed that, in the recent past, the faculty at the Qwaqwa Campus has experienced an increase in the enrolment figures for teacher training.

"Numbers in our initial teacher education programmes grow in leaps and bounds and we produce some of the best teachers in the country. We are proud to say that on graduation day, our students receive at least two things, i.e., their qualifications as well as entry into the teaching profession," added Hlalele.

Some of the shining examples that Dr Hlalele referred to, are Tebello Tshabalala (English), Mthobisi Khumalo (Mathematics), Thabo Mohapi (Physical Sciences), Lehlohonolo Khanye (Accounting) and Yvonne Tsotetsi (Business Studies). All of these are educators at Lekgulo Senior Secondary School in Qwaqwa and have each produced a 100% pass rate in the 2014 examinations.

There is also Nape Motloung, whose excellent Mathematics results at Botshabelo's Lefikeng High School have placed him as the Top Mathematics Educator in the Free State. Motloung's consistent excellent results have also placed his school in the Top 10 of the Best Performing Schools in Mathematics. This has also won his school R100 000 from the Free State Department of Education.

At yet another Qwaqwa school, Sekgutlong Secondary, Malefetsane Mokomotoane's Mathematics results over the years have earned him a runner-up prize in the category Excellence in Teaching Mathematics at the 2014 National Teachers Awards hosted by Minister Angie Motshekga.

"I am proud to have had 98% of my learners pass Mathematics, with 10 distinctions," said an elated Mokomotoane, who has just been appointed Principal of Selelekela Secondary School in Qwaqwa.

"Having achieved an average of 59%, my highest ever, has taught me and my learners that through hard work, anything is possible," added Mokomotoane.
