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.

A magnificent Winter Graduation Ceremony

The way to immortalise a person, is to live by his example. PhD and master's graduates were imbued by the following message from Dr Khotso Mokhele, Chancellor of the University of the Free State (UFS), during the UFS Winter Graduation Ceremony: to follow Nelson Mandela's majestic example is to guarantee that his life was not in vain.

Dr Mokhele honoured the graduates for their achievements "that clearly did not come easy", referring to the sacrifices on their part and the role of their support structures.

He also praised members of the UFS' leadership team who contributed academically to the excellent standards. Prof Teuns Verschoor, former Vice-Rector: Institutional Affairs, and Prof Driekie Hay, Vice-Rector: Academic, were especially mentioned for their role as respectively co-promoter and promoter of two PhD graduates.

A total of 63 doctorates and 414 master's degrees were awarded to graduates from South Africa, Nigeria, Lesotho, Uganda and Zimbabwe on Thursday 27 June 2013.

On the previous day, the School of Open Learning kicked off the graduation event by conferring 320 qualifications.

The graduates, most of them full-time educators, received qualifications ranging from certificates to diplomas.

"I hope that you will plough back what you have learned and that this qualification will make you a better educator, an inspired one, one that will relentlessly put your efforts into increasing a better future for our children," Prof Hay said, highlighting challenges in South Africa's education system.

"Become enthused, obsessed and passionate to change the education system. Be the change agent in your schools to contribute in giving the quality education our children so desperately need," she said.

An exceptional moment at this year's graduation ceremony was when the two daughters of an academic, Prof Dave Lubbe of the Centre for Accounting, obtained their master's degrees. "It is indeed a highlight in my career that my daughters received their master's degrees cum laude at the same graduation ceremony, under my supervision!"

Prof Lubbe's two daughters, Nandi Lubbe and Leandi Steenkamp, both received their MCom with distinctions in Accounting. They completed their degrees under the supervision of Prof Lubbe and Nandi also won the Dean's medal as the best M student in the Faculty of Economic and Management Sciences.
