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.

Growth in scholarly books ‘is remarkable’

The UFS has shown steady growth in its output of scholarly articles. Dr Glen Taylor, Senior Director of Research Development, says “the UFS has shown remarkable growth in the output of scholarly book publications over the recent years." The 13,83 subsidy units from scholarly books in 2010 has grown to 98,52 in 2014, elevating the university to fourth position nationwide. 

“It is encouraging for the research office to see that the number of books has increased over the years, together with the units we receive for subsidy, but also the steady increase in the quality of our scholarly books in general,” he said.

Contributors to the growth in scholarly publications include Dr Christian Williams of the Department of Anthropology, celebrated journalist Zubeida Jaffer, as well as JC van der Merwe, the Deputy Director of the Institute for Reconciliation and Social Justice (IRSJ), and Dionne van Reenen, researcher and PhD candidate at the IRSJ. Dr Williams received the 2016 Distinguished Scholar Book Prize at the official opening of the UFS earlier this year. The book, National Liberation in Postcolonial Southern Africa: A Historical Ethnography of SWAPO’s exile camps, is the first full-length scholarly monograph on SWAPO and Namibians in exile. 
 
The 13,83 subsidy units from scholarly books in 2010 was approximately a 10% increase in outputs from 2005 to 2010. In 2010, the higher education institution sector as a whole produced 401,68 units from scholarly books. The UFS contribution of approximately 3,44% put the university in tenth position. 

“The increase in subsidy for scholarly books should stimulate the sector further, and an increase in scholarly books is expected, which complements the university research output strategy to become a leading research-intensive institution,” Dr Taylor said.
