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.

“We relied on outsiders to document our histories.” – Zanele Muholi delivers Women’s Day Lecture

“Our society is decaying because of hate crimes against LGBTI groups. You can’t say it does not affect you, because each of us is at least connected to one person [of LGBTI orientation].”

These words by Zanele Muholi, photographer and visual activist of LGBTI rights, who delivered the Women’s Day Lecture. The event commemorated Women’s Day and took place on Thursday 7 August 2014 at the Bloemfontein Campus. The lecture was hosted by the Centre for Africa Studies, as part of their Gender Studies Programme.

Muholi screened photographs featuring lesbian couples and recounted their all-too-real life stories. Her work emphasises the importance of queering the normative gaze by representing black lesbians in ‘straight’ portraits in a collection of works titled ‘Faces and Phases’. By focusing on lesbians in her work, Muholi shows that women in same sex relationships are just women, with the same dreams and aspirations as their heterosexual sisters.

But lesbian women carry an additional, grave fear – that of corrective rape. Muholi speaks on this topic in the video, ‘We live in fear’, which she screened during her talk. The documentary features the lives of lesbian women in Kwa Thema township in Johannesburg. Shockwaves spread through this settlement in 2008 after the brutal killing of a lesbian woman and the ensuing series of hate crimes against the LGBTI community.

Zanele describes her work as “documenting our own stories. For years we relied on outsiders to document our histories. We should do it ourselves.”
