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.

R8,2-million boost for UFS Qwaqwa campus
2005-01-21

The management of the University of the Free State (UFS) has approved an allocation of R6,8-mililon for upgrading of residences and R1,4-million for other upgrading of the UFS Qwaqwa campus.

According to the Head of the Qwaqwa campus, Prof Peter Mbati, the management also decided that a maintenance manager should be appointed, who will be responsible for dealing with routine maintenance on the Qwaqwa campus.

Prof Mbati said these developments were a major step forward for the Qwaqwa campus as it once again showed management’s commitment to the campus which was incorporated into the UFS in January 2003.

“We can systematically begin to tackle the huge backlog of needs – in terms of maintenance and upgrading – that has built up over many years.

“The new maintenance manager – once appointed – will also ensure that we shorten the turn-around time for addressing routine maintenance issues and in this way improve service delivery on this campus.

“This is not just a financial boost for the campus but I view it as a major boost for staff and student morale. With this commitment from management, staff and students should also commit themselves to the future of this campus,” Prof Mbati said.
