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 Bloemfontein Campus of the University of the Free State was abuzz with excitement as first-year students arrived at their new homes and residences, brimming with enthusiasm at starting a new chapter in building towards a professional career.

Although there were some mixed emotions about leaving the nest, most students were excited about the times ahead as they moved into their residences on 20 and 21 January 2017.

Student life and building a career

“I am looking forward to a new adventure, to student life and living at university. Also to build my future here,” said Veruska van Schalkwyk, as her parents, who had driven all the way from Springbok in Northern Cape, helped her unpack at Harmony residence.

Veruska, who will be studying Nursing, said she loved TV programmes like Grey's Anatomy. “Nursing has always been my passion and something I loved. I have always loved helping people.”

University provides a prosperous future

For Okuhle Gubevu, who will also be a first-year in Harmony, the UFS is the ideal place to further her career. “Out of all the research I have done, the University of the Free State is the one university that has a prosperous future for me in my ventures to become an accountant,” she said. “Because of that and because it is not too far from home, I decided on the UFS.”

Mopeli Lebohang will be staying in Outeniqua residence and is keen to work hard. “I heard the course I am studying, B Accounting, is the third toughest course at the university,” he said. “I am excited, because I like challenges.”
