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.

“I, too, am an African,” says visiting US drama professor
2013-03-06

 
Africans are of blood and of soil, says Prof Charles Dumas in his inaugural lecture at the UFS. Speaking on the topic I, too, am an African, Prof Dumas reminisced about his life and experiences on the continent.

What is an African? Is it those born in Africa, defined in racial and genealogical terms, or those who identifies with the continent in nationality and ancestral location? Did the descendants of enslaved Africans in the US, the Caribbean or Brazil lose their Africaness when their ancestors were put on slave ships to the New World?

These were some of the questions raised by Prof Charles Dumas, visiting senior professor in the Department Drama and Theatre Arts, in his inaugural lecture at the university.

Proclaiming attachment to the continent, Prof Dumas told his audience there are two types of Africans: Africans of the blood and Africans of the soil. In a speech titled, “I, too, am an African,” he stated that he lay claim to his ancestral birthright not because of blood relationship to an identifiable ethnic group or birthright to the continent, but because he earned it.

“I suggest another way that one can be an African, is through trial and struggle to be reborn an African in spirit. It is a ritual journey that may be taken by anyone. For, after all, if we are to believe the anthropologists who tell us that human life as we know it began in the Olduvai Gorge, genetically we are all African in origin.”

Prof Dumas, a senior professor at Penn State University in the USA, took the audience on a journey of his experiences on the continent, starting in 1978 when he first came to South Africa as a legal observer. Noticing the changes between Apartheid and today’s South Africa, he said this generation are committed to learn from each other – and that is the most important, he said.

“With their hopes and aspirations they earnestly desire to live in the new South Africa that we promised them. We must support them in their effort. It is time we stored our old baggage in the closet.”
