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.

To be an ambassador for the University of the Free State (UFS) is a goal of the Odeion String Quartet (OSQ) and that is exactly what it will do through international visits to Tanzania and Austria. The OSQ, the only residential university quartet in South Africa, will play concerts abroad, share knowledge and build relationships.

It visits Dar es Salaam, Tanzania, from 17 to 20 November 2016 and Austria from 29 November to 4 December 2016. The quartet, which constitutes string lecturers at the Odeion School of Music, consists of Samson Diamond, Sharon de Kock, Jeanne-Louise Moolman and Prof Anmari van der Westhuizen Joubert.

A humbling experience
The OSQ was invited by Hekima Raymond, founder and conductor of the Dar Choral Society, to Tanzania to assist the symphony orchestra. Raymond is a self-taught pianist and conductor and was nominated for a BBC Outlook Inspirations award in 2016.

The quartet will lead the string sections of the orchestra, consisting of members from Uganda, Kenya and Tanzania, performing Beethoven’s fifth symphony and Verdi’s Requiem.

According to Diamond it is a humbling experience, an opportunity to extend their services and help establish the Dar Choral Society. “You are part of something really special, because the circumstances are remote if you compare it to what we have here.”

He means it is important to have a real African footprint and being involved there can later serve as a platform for UFS recruitment.

“You are part of something really special,
because the circumstances are remote if
you compare it to what we have here.”

South African and Austrian collaboration
According to Prof Van der Westhuizen Joubert it is an honour to play in Austria, as Europe is a centre for classical music. The OSQ will play concerts at the Alte Schmiede, Vienna, and the University of Salzburg.

The concert on 4 December 2016 at the University of Salzburg’s Mozarteum is a highlight because the UFS will have the opportunity to build relationships with the famous music school.

Prof Van der Westhuizen Joubert said it would be a South African/Austrian collaboration. “We will bring them South African works (Mokale Koapeng, AJ Feder, Arnold van Wyk and Peter-Louis van Dijk) and will be playing Austrian contemporary string quartets.”
