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.

The University of the Free State’s UFS) Family Maths and Family Science project has received a R1 million sponsorship from Old Mutual for 2013. This is a three-year project whereby the university’s School of Open Learning aims to demystify mathematics and science in the early school years, as stated in their mission. The launching ceremony took place on 1 February 2013 at the UFS Campus.

The sponsorship was made available by Old Mutual, but will be managed by the project management group, Ilima Trust.

The UFS received R30 million altogether from Old Mutual for the use on various projects.

Except for the Family Maths and Family Science project, the Schools make over project and the Internet Broadcasting Programme will also benefit from this donation.

“Ilima has a hands-on relationship with different projects and is the public face for the FM & FS sponsorship,” said Mr Graham McCulloch, Ilima Trust representative for the Free State.

“Today is the first step on the long road to improving math and science in the country,” McCulloch said.

Dr Cobus van Breda, Director of the Science-for-the-Future Unit  says the Family Math and Family Science Project makes science and math accessible to children and their parents in the early years, with the aim of developing positive attitudes towards these often difficult school subject.

“This project aims to empower educators, parents and student educators by iving support and training in hands-on teaching methodologies.”

Learners, educators and parents from 18 schools in Thaba Nchu and Botshabelo will benefit from this project. Teachers will receive training at the UFS and then return to their community to train parents and to teach learners. Teachers will also receive activity material to use in classrooms.

“The selection of the 18 participating schools took place by identifying feeder schools of secondary schools from the UFS School Change Project, trying to create a whole-school development,” Van Breda said.
