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.

Now is the right time to talk, says Njabulo
2015-04-20

Studying at a multicultural campus adds a lot of colour and spice towards every student’s experience, and it also offers some necessary challenges.

This belief is held by the Qwaqwa Campus SRC member responsible for RAG, Community Service & Dialogue, Njabulo Mabaso.

“Our multi-culturalism should be our uniting force, especially at this time in our country. What started as a one-person protest against the Cecil Rhodes statue at UCT should be used to broaden our view in relation to challenges that we are still facing as students and as a country. We need to talk more”, said Mabaso, a final-year BEd FET Languages student.

“Now is the right time for us to really talk about issues affecting us as young adults. Matters of collective interest like pregnancy rates, alcohol and substance abuse, sexism, crime, xenophobia, etc. need to be tackled”, added Mabaso, a weightlifting fanatic.

“As the student leadership, we intend working closely with community structures as we come from the very same communities. We must not wait for Mandela Day to do good.”

“My portfolio, together with Arts and Culture and Sports Affairs portfolios, can create that necessary social cohesion that we as students and our communities need so much.”

Mabaso said that all perceived taboos should be dealt with.

“Our programme this year encourages open dialogue. Nothing should still be treated as a ‘no-go area’ if we are to survive the scourge of HIV. We must talk openly, despite the cultural challenges that might restrict us. We must talk about homophobia. We must talk about rape. In fact, how many students – male and female – really understand what rape is? Does culture even recognise the ‘no’ factor associated with rape? It is important that we should not leave it until it is too late. We must not wait until it is his word against hers. We must deal with these matters now. The right time to engage is now”, he added.
