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.

Kovsies ready for national "sêr" competition

A group of talented Kovsies, each with a smile, are busy packing their cases. After winning our annual “sêr” competition, the “sêr” groups of the Sonnedou and Veritas Residences are getting ready to represent the University of the Free State (UFS) at the National “Sêr” Competition, which is taking place at Stellenbosch University (US) this year.

After months of intensive rehearsals, tension and excitement, the two city hostels are getting ready to compete against other South African universities for the trophies for the best women’s and men’s “sêr” group.

This competition, which is taking place on 4 September, is a major event on the cultural calendar. Although our representatives are from city residences, they have worked as hard, if not harder, than the resident students.

Sonnedou also participated last year, when the competition took place at the University of Johannesburg (UJ). The group then came second and they are ready to bring home the first prize this year. Their repertoire include, amongst others, “Nkosi Sikeleli i'Afrika” and “Kinders van die Wind” by Koos du Plessis.

According to Herman Naudé, head student of Veritas and second tenor in the “sêr” group, the group is very excited about their participation in the competition. With songs like “Lief vir alles hier” by André Schwarts and “Sweet child O’ mine” by the group Guns ‘n Roses, they plan to fulfil the expectations of their fans and the adjudicators. “I really think we have a good chance to win this year,” says Herman. –Lize du Plessis
