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.

Ms Patricia de Lille, the Leader of the Independent Democrats, recently paid a visit to the School of Management at the University of the Free State (UFS). She spoke to students in the MBA programme about the leadership challenges South African business leaders are facing.

Ms De Lille voiced her opinion on many current issues, such as corruption. “Business is standing back with its arms folded and leaving everything to government. In fact, business is doing something very similar to what it was doing during apartheid,” she said.

She added that a business leader and his or her business could be found behind every corrupt transaction. “It is a relationship involving more than one party. If someone accepts a bribe, someone else is paying a bribe,” she said.

Ms De Lille lashed out at business leaders who received extravagant salaries and bonuses even after they had been asked to leave the company. “South Africa needs a new generation of business leaders that truly know the difference between right and wrong,” she pointed out. “And it’s wrong to demand the rest of your contract’s money and bonus after you have been fired because you obviously didn’t do your work.”

Ms De Lille also focused on the role that South African business played. Business should engage with the government to identify problems and find solutions to speed up transformation. “We need young entrepreneurs that are patriotic and think out of the box,” she said.
