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.

“I’ve used each highlight of my career as a benchmark for greater accomplishments.”

These are the words of Bongani Njalo, who was selected as one of the Mail & Guardian 200 Young South Africans together with Adv Loyiso Makapela, Junior Lecturer at the University of the Free State (UFS) Law Faculty. Njalo was recognised in the Arts and Culture category for his outstanding contribution to the art scene.

Getting to know the artist

The fine art graduate has worked on different art projects in several cities, and is currently the project co-ordinator for the Program for Innovation in Artform Development (PIAD). PIAD is a programme developed by the UFS and the Vrystaat Arts Festival, which focuses on how technology, interdisciplinary and experimental arts can connect with and impact on communities.

Aspiring artist on the move

Soon, this young artist will be on the move again, as he has been accepted into the Internal Leadership Program in Visual Arts Management at Deusto Business School, taking place in Bilbao in Spain in November and in New York next March.

When asked about the nomination, Njalo simply said: “To be honest with you, I don’t feel any differently whatsoever. I now feel I have more work I’d like to do.”

A man of many talents

Not only was Njalo an intern at the Mandela Bay Development Agency where he compiled the book entitled Art & Artists of the Eastern Cape, but he also curated the Eastern Cape Artists Exhibition at the Grahamstown National Arts Festival in 2011.

In 2012, Njalo was invited to curate a group exhibition, Beehive, for the Cape Town International Month of Photography Festival, and in 2014 he won the David Koloane Mentorship Award.
