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.

Get your dual-frequency card
2015-07-28

 Staff members and students, who are the owners/drivers of motor vehicles, are kindly requested to purchase the dual-frequency cards that replace their current student or personnel cards.

The dual-frequency cards can be read by the distance readers at the entrance gates. Card holders will no longer have to swipe their cards or stop; the boom will open automatically and card holders will be able to drive through.

Please note that this arrangement only applies to valid card holders entering the campus – on leaving the campus, they will again have to swipe their cards past the card readers.

This improves the traffic flow and prevent possible delays at the gates.

Pay for your card

Electronic fund transfers: Absa Bank: 1 570 8500 71, Ref: 1 413 07670 0198, OR pay the R65 at the UFS Cashiers, Thakaneng Bridge. 

Take your existing personnel or student card, together with proof of payment, to the UFS Card Division, Bloemfontein Campus, Thakaneng Bridge, to have your photo taken and your new dual-frequency card issued.

The UFS Cashiers will provide assistance between 09:00 and 14:30, and the UFS Card Division between 09:00 and 15:00.

Your new card

Permission to access specific UFS buildings or facilities linked to your existing card, will automatically be linked to the new card.

The new card is marked ‘dual’ on the back in the right, bottom corner.

The UFS would like to thank you for your cooperation in the successful implementation of access control on the UFS Bloemfontein Campus.
