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.

The student representative councils (SRC) from the Bloemfontein and Qwaqwa Campuses are currently visiting Rwanda, Uganda and Kenya as part of the university’s Global Leadership Programme (GLP). The student leaders left on 9 June 2013 for a two-week trip to these countries, meeting with NGO’s, businesses and political leaders to gain insight and leadership skills. Their trip will also include a visit to the Kigali and the Nyamata Genocide Museums.

The University of the Free State has a long history of mentoring and fostering student leadership through international partnerships.The GLP was established in 2011 by Prof Jonathan Jansen, Vice-Chancellor and Rector. The programme identifies the need for dynamic and innovative leadership in a country faced with many challenges.

During 2011 the SRC had the opportunity to tour the United States, but this year’s aim shifted to partnering with African Institutions. The focus is currently on the African continent and the lessons that can be learned from each of these countries. During the students’ visit to Rwanda – where they will spend six days – they will pay special attention to elements of leadership and reconciliation. This theme ties closely into the process of transformation and reconciliation at the Bloemfontein Campus.

The SRC has a travel-blog where they constantly post information, facts and their experiences during their visit to these African countries. They are set to return on Sunday 23 June 2013.
