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.

Young academics empowered in research environment
2009-05-05

 
Young academics who attended the workshop are, from the left, Mr Lehlohonolo Mathengtheng, Department of Medical Virology; Dr Annelize Venter, Research Directorate; Mr Ferdi van der Walt (Facilitator), University of Johannesburg; Ms Telishia Flusk, Research Directorate; and Mr Dirk Strydom, Department of Agricultural Economics.
The Research Capacity Development Office under the auspices of the Directorate for Research Development Office endeavours to empower young academics at the University with skills to enable them to be established within the competitive mainstream of research. The Office recently organised a series of thematic workshops aimed at assisting young academics to acquire the “know-how” in terms of developing and writing proposals including, writing for funding. Such strategic support has lead to the University recording an increase in funding from the Thuthuka Programme of the National Research Foundation over the past five years. Thuthuka grants are made available on a competitive basis where applications are subjected to a peer-review process. This suggests that the quality of applications from the University is of a high quality.

The recent thematic workshops were facilitated by Prof. L Lategan, Dean for Research at the Central University of Technology as well as Mr Ferdi van der Walt, from the Research Office at the University of Johannesburg.
