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.

Breakfast in aid of hungry students
2011-06-01

Our university again proved that it cares for the welbeing of its students when a sum of money was presented to the No Student Hungry Project during a breakfast function.

The Centre for Health and Wellness at the UFS organised the event, not only to introduce the scheme to staff and individuals and thank those concerned for their contributions, but also to present the project organisers with a donation of R50 000. Mrs Grace Jansen, wife of Prof. Jonathan Jansen, Vice-Chancellor and Rector and Dr Carin Buys, wife of Mr Rudi Buys, Student Dean, started the project this year after a study found that 20% of students at the UFS have to study on an empty stomach and that this often leads to students leaving the UFS prematurely.

Ms Tanja Malherbe, mistress of ceremonies, said that the project is blessed because it developed from the founder members’ love for the students. The project currently provides 6 000 deserving students with a meal per day.

Prof. Jansen said that although the university encourage academic success, the UFS is also ready to show its mettle on a humanitarian level. “We don’t want students to only study together, but also to eat together.” He added that food can promote a feeling of fellowship, gives comfort and is also a symbol for caring. “It is bad to be hungry, no matter what the colour of your skin. Especially when other people have food and you don’t.”He concluded by saying that we are blessed by giving to other people, and by giving, we also receive.

Ms Tarryn Nell, also from the centre, supported him by comparing caring to candlelight. “It drives the darkness away, involves compassion and gives direction. When two people can get things to change, the rest will follow.” She encouraged the audience to share their warmth, time, knowledge and resources with other people.

During the event, a picture summary also referred to two recent projects the centre hosted. The first was a free medical screening test for staff members and the second a temporary remembrance rose garden, representing the five main causes of deaths in the country. These causes are HIV, ischemic heart disease, stroke, tuberculosis and interpersonal violence.

The proceeds from Prof. Jansen’s book “We need to talk,” will be donated to the project. Persons wishing to make a contribution, can make a payment to the following account: ABSA 157085 0071, reference number 146 674 604, account number 0198, branch code 632 005. Deposit slips can be sent to pelserr@ufs.ac.za.
