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.

South Africa and the rest of Africa might be standing on the edge of a cliff and therefore conversations are necessary to avoid tipping over. According to Prof Hussein Solomon that was why a conference to address these issues was recently co-hosted by the University of the Free State (UFS).

Prof Solomon, Senior Professor of Political Studies and Governance at the UFS, said the continent and country needed to make the right decisions. “These right choices refer to the correct economic, political, and social policies.”

International delegates attend
Delegates from India, Japan, Zambia, Lesotho and South Africa attended the conference, called A View from the Precipice: Critical Reflections on South Africa and Africa in the 21st Century, on 13 and 14 February 2017 on the Bloemfontein Campus. It was co-hosted by the UFS Department of Political Studies and Governance, Jawaharlal Nehru University (India), Centre for the Engagement on African Peace and Security, Southern African Centre for Collaboration on Peace and Security and Osaka University (Japan).

Prof Solomon said external actors provided a useful mirror as they gave an idea of how Africa and South Africa were viewed from abroad.

Creating a knowledge-sharing forum
“It is not just about sharing knowledge, but creating a forum for sharing knowledge,” said Prof Virgil Hawkins from the Osaka School of International Public Policy Studies.
Prof Hawkins, who is a visiting professor at the UFS, said a conference like this was one of the cornerstones of the relationship between the UFS and Osaka University. Prof Solomon is also a visiting professor at last mentioned university.

Highlights of conference
Prof Solomon said some of the discussions included that “the ANC government is in crisis and is dragging the rest of the country with it”. Another participant said that 80% of the jobs in the next 20 years had not been created yet – which put the relevance of tertiary education in the spotlight.
