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.

Qwaqwa Campus graduates encouraged to face the world with confidence
2015-05-14

 

Speech: Nikiwe Bikitsha 

The Qwaqwa Campus of the University of the Free State conferred over 800 degrees during this year's graduation ceremonies that were held on 8-9 May 2015. These included four PhDs in Natural and Agricultural Sciences.
 
The guest speaker, eNCA's Nikiwe Bikitsha, encouraged graduates to make it their business to learn about everything, no matter where they go.
 
''Having a qualification does not mean that now there will be tasks that are beneath you. No task should ever be too insignificant for you to do,'' said Bikitsha.
 
''You should make it your business to know every aspect of your work because that is where you get opportunities. Find somebody to help you along. Asking questions sharpens your skills and broadens your horizons. Asking questions also communicates to your employers and associates that here is someone who needs to be groomed and nurtured.'' she added.
 
In his congratulatory message, UFS Chancellor, Dr Khotso Mokhele, challenged the graduates to face the journey ahead with confidence.
 
''The journey ahead depends entirely on you, '' he said.
 
''You may think it depends on your parents, your country or the government. But the truth is that this is your journey. What is critical now is the kind of choices you are going to make. There will be stumbling blocks along the way, but you have to make it through,'' said Dr Mokhele.
 
''As the university'’, he continued, ''we hope you are going to make transformative choices that will impact positively on our people, our country and our continent''.
 
Dr Mokhele paid a special tribute to the four PhD graduates, three of whom matriculated at  local Qwaqwa schools, with the fourth matriculating at Mafahlaneng, Tweeling.
 
World-renowned composer and playwright, Dr Mbongeni Ngema, provided musical entertainment.
 
Both ceremonies were attended by community, business and traditional leaders in the Maluti A Phofung area.
 
Also in attendance were over 500 grade 12 learners from Qwaqwa, Kestell, Harrismith and Bethlehem schools.
