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 attracts excellent and diverse students

When Thato Monkoe and Matshediso Mokoena sat for their final matric examinations in 2014, all they had on their minds was not just passing, but passing well. Little did they know at that time that passing well would place so much responsibility on their shoulders.

 

Both Thato and Matshediso come from rural and disadvantaged backgrounds. They are first-year students at the Qwaqwa Campus of the University of the Free State, and are the first in their respective families to study at a university.

 

Thato describes his situation as “sad and good at the same time”.

 

“It is good, because I am the first one at home to have completed my matric and to have gone on to study at a tertiary institution. At the same time, it is sad as I feel sorry for my siblings who, for various reasons, did not have similar opportunities when they opted out of school”, said Thato, a BEd student.

 

”Now my sister and brother, as well as the entire family, perceive me as the one with brains, and this makes me uncomfortable. However, I am up for the challenge to be the first one to graduate with a degree in my family”.

 

Matshediso Mokoena, a BSc student, who obtained distinctions in Mathematics, Physical Sciences, and Life Sciences last year, concurs with Thato.

 

”As much as my family is supportive, there is always pressure as they expect the best from me,” she said.

 

“The pressure does not only come from my family. My entire community looks up to me, and they can’t stop talking about my achievements”, Matshediso revealed.

 

Both Thato and Matshediso are, however, happy that the dark cloud of doubt about academic achievement in their families has finally disappeared.

 

“At least someone in my family is hard at work carving her future, and willing to set a good example. That person is me”, said Matshediso, who aspires to be a medical doctor, and has a younger sister in Grade 8.

 

Thato and Matshediso are just two of hundreds of students making good use of the University of the Free State’s commitment to attract excellent and diverse students at both undergraduate and postgraduate levels, as reflected in the Strategic Plan 2015-2020.
