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.

Mandela Day celebrated with R5 coin laying
2012-07-09

On 18 July 2012, the University of the Free State (UFS), in partnership with Pick n Pay Hyper in Bloemfontein, will celebrate Nelson Mandela Day with a special R5 coin laying ceremony.

The festivities kick off at 12:00 on the Red Square at the Bloemfontein Campus.

Emeritus Archbishop Desmond Tutu will make a special appearance at this event and also deliver a short message.

Schools in the vicinity, UFS staff and students and the public are invited to take part in the coin laying ceremony.

Ms Marissa van Jaarsveld, the coordinator of the Nelson Mandela Day celebrations at the UFS, says the money collected at the event will be used to benefit the No Student Hungry (NSH) campaign, as well as Bloemfontein Child Welfare. NSH is an organisation on the Bloemfontein Campus that provides food bursaries to hungry students with good academic records.

Requests have been sent to schools to collect R5 coins for the event and representatives from the schools will attend the coin-laying.

These schools will be acknowledged for their contributions and there are prizes up for grabs for the primary and high schools that collect the most money.

Learners will deposit their coin contributions during the 67 Minute programme of giving back to the community and they will take part in fun activities. Participating schools are encouraged to be as creative as possible when handing over their R5 contributions.

On the day, there will also will be people with tins at the main entrances to the university for those who want to make a contribution.

The NSH-campaign will also show its support for eradicating world hunger on this day by helping Pick n Pay Hyper in Bloemfontein to package food parcels for the Stop Hunger Now campaign. The packaging of the food parcels will also take place at the UFS.

Members of the public and the media are invited to attend the festivities.
