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.

More than 200 people, amongst them the Deputy Minister of Higher Education and Training, Prof.  Hlengiwe Mkhize, came together at our university to reflect on the life of ANC Women’s League stalwart Charlotte Maxeke, during the Charlotte Maxeke Memorial Lecture organised annually by the Free State Provincial Government and our university as a lead-up to National Women’s Day on Tuesday, 9 August 2011.

This year was the fourth memorial lecture and Prof. Mkhize delivered the main address under the theme “Women’s access to education, science and technology for economic growth and development in bringing about positive change, living in extraordinary times”

Prof. Mkhize told guests Charlotte Maxeke’s life was too rich and complex to capture during the night and listed many of Maxeke’s achievements during her life and times. These included Maxeke being the first woman to graduate with a science degree from the University of Wilberforce, Ohio.  Prof. Mkhize said Charlotte Maxeke’s science degree was not a personal achievement, because she went back to the people and served by opening the Wilberforce Institute in Evaton, Vereeniging, after her return from the United States.

Prof. Mkhize applauded our university for organising the lecture, saying the university’s commitment was appropriate for the contribution Charlotte Maxeke made to women’s empowerment.  She said government have a huge interest in our university and said the lecture provided an opportunity to dialogue and to use the experience to improve the country’s institutions. Delivering the last part of her address, Prof. Mkhize said she hopes the lecture will lead to great things, with the local community also becoming involved in organising the event.

Dr. Choice Makhetha, Acting Vice-Rector:  External Relations, announced at the event that the university will open a women’s memorial garden on Tuesday, 9 August 2011  to honour women who made a contribution in society.
