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.

One of the UFS's newest members welcomed at international organisation.

Prof. Hussein Solomon

One of the University of the Free State’s (UFS) newest members of excellence was recently welcomed as a new member at the relatively new, yet influential, internationally renowned Our Humanity in the Balance (OHIB) organisation. Prof. Hussein Solomon, a month old Senior Professor in Political Science at the university, said he has always wanted to have made a difference in people's lives and dreamt of becoming part of an organisation such as the OHIB. Proofing of Solomon's dedication to his roots, he believes his focus must remain with the African continent. ''I would like OHIB to focus on making the secession process in Sudan as peaceful as possible as well as focusing on ending the ongoing conflicts in Somalia, the Ivory Coast and the Democratic Republic of the Congo. These are immediate goals. In the medium term we need to examine the issues of democratic transformation in countries like Swaziland and Zimbabwe.''

As this Kovsie has worked in peace NGOs, advised diplomats and acts as a serving officer in the South African Air Force and an academic, the compilation of the OHIB board consisting of academics, former senior diplomats and military people and peace activists would be nothing new to him. ''My role is essentially to bring these disparate communities together and to focus energies on a common project. At the moment much attention is being focused on current developments in Libya.''

Other accomplishments of this former Tuks lecturer include Visiting Professor at the Global Collaboration Centre at Osaka University in Japan, Visiting Fellow at the London School of Economics and also respective membership on the Security Council of the Gerhson Lehrman Group of Companies, the International Steering Committee of Global Action to Prevent War, and the International Advisory Council of the Toda Institute for Global Peace and Policy Research in Hawaii. Prof. Solomon was selected in 2008 to serve on the Nelson Mandela Chair of African Studies at Jawahrlal Nehru University in New Delhi, India.

His current area of research expertise include conflict and conflict resolution in Africa; South African Foreign Policy; international relations theory; religious fundamentalism and population movements within the developing world. His publications have appeared in several countries around the world including Switzerland, The Russian Federation and Japan.
