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.

‘I’d rather wake up at 8’clock for nothing than to sit at home’
2015-08-26


Tawanda Kaseke is on a mission to give back to the community one holiday at a time.

Studying towards a degree is one aspect of being a student. Investing time in worthwhile extra-mural activities forms a significant part of your student years. Tawanda Kaseke demonstrates how volunteering time to a good cause makes for a responsible student and citizen.

 

The second-year Public Administration student’s moral obligation to community development led him to spend approximately two months of his June 2015 holidays volunteering. Serving as a volunteer Admin intern at Afrika Tikkun’s ignited his aspiration to assist children from underprivileged communities to access education.

 

From cradle to career: a journey from infancy to varsity and beyond

 

Afrika Tikkun is a non-profit organisation (NGO) that works toward a future where today’s children and youth are tomorrow’s productive citizens. The NGO adopts a cradle-to-career model, which invests in the development of disadvantaged children from early infancy through young adulthood into the world of work.

 

Raising funds for the “Like Change” movement – a division of the “From Cradle to Career” project - is Tawanda’s primary objective for his November to February summer vacation.

 

Tawanda encourages social media users to contribute by clicking on the “Like” option on the ‘Like Change’ Facebook page.  A private company automatically donates R35 towards the education of an underprivileged child on your behalf.

 

Making your mark begins with a dot; university holidays are Tawanda’s dot. A passion for community development and a willingness to volunteer one’s time can go a long way in making South Africa a better place.
