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.

Women must fight for equal opportunities - Motshekga

“We will not know peace and prosperity unless all women are free. We must open opportunities for women and make sure that we achieve the necessary progress. I believe this would be the best way to honour the life of Charlotte Maxeke.”

This rallying call for action was made by the Minister of Basic Education, Ms Angie Motshekga (pictured), in her speech to commemorate the life of Charlotte Maxeke, a woman she described as “a heroine” to all South Africans.

The University of the Free State (UFS), in conjunction with the Free State Premier’s office, presented the annual Charlotte Maxeke Memorial Lecture at the Main Campus in Bloemfontein to once again honour this remarkable African woman as part of celebrating Women’s Month.

“We must ensure that we act consciously to extend equal opportunities, freedom and justice to all women,” she said. “We must put all our energies together in this task of uplifting women and children.”

She said that even though women had made considerable strides since the advent of democracy in South Africa, especially in government, much still had to be done to ensure equal opportunities for all women.

“There’s a 40% women representation in government, but the question we should ask ourselves is: What value does this representation bring to the life of an ordinary woman? What impact does it have on her life?” she asked.

She said women were still less represented in managerial positions. “Sexism requires the same amount of energy that we use to fight against racism,” she said.

She also announced that the government had decided to declare the graves of Charlotte Maxeke, Lillian Ngoyi and Helen Joseph as national heritage sites.

The well-attended lecture was entitled: United in action to make 2010-2020 a decade for women in Africa.

Among those present were members of the ANC Women’s League, who came in buses and mini-buses; Dr Allan Boesak and his wife; past and present Free State MECs; and the Vice-Rector of External Relations at the UFS, Prof. Ezekiel Moraka.
