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.

Make the right choices and you will succeed, Prof Jansen advises learners
2014-05-30

“You can make a choice today that will end up with you being pregnant, having babies, being unemployed, sitting at home like some of our brothers and sisters, uncles and aunts. Or you can make a different decision – and that decision is about you working so hard that you earn entry into the University of the Free State, get your degree and become great, not only in South Africa, but in the world.”

This was the message from the UFS’s Vice-Chancellor and Rector, Prof Jonathan Jansen, who addressed prospective Kovsies during our Open Day on the Qwaqwa Campus on Saturday 24 May 2014. Prof Jansen advised all learners to always make the right decisions.

“The first right decision is to pass well. You must go for 60%, 70% and 80% passes. Set yourself a target and do not just strive to pass, but to pass well,” Prof Jansen told a packed Rolihlahla Mandela Multi-purpose Hall, with learners coming from as far as Ficksburg, Lindley and Koppies.

“The second thing that you need to do, is to believe in yourself. Do not believe people who tell you what you can or cannot do. Believe in what you can do,” said Prof Jansen.

“Thirdly, you have to get up and do things for yourself. You have to work hard, sleep less and study hard. Don't accept excuses. If you can do these three things, then the best place to study is the University of the Free State. Believe that the sky is the limit.”

“We learned a very valuable lesson here today,” said Tumelo Mofokeng from Nkarabeng Secondary School in Kestell.

The fun-filled programme included performances and messages of encouragement from current students who have been part of the unique Leadership for Change Programme. This programme equips first-year students with skills to reflect, dialogue and engage on issues of diversity and leadership.
