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 Centre for Education Development (CED) at the University of the Free State launched its Family Math & Family Science roll-out initiative in the Free State and Northern Cape Province at the beginning of 2009. As part of the quality assurance process, a Family Math & Family Science Summit was recently held at the CED to reflect upon the roll-out strategy during 2009. Delegates as far as Qwaqwa in the Free State and De Aar and Springbok in the Northern Cape province, sponsors and other role-players attended the summit to share information regarding the impact and best practices of the roll-out strategy.

The mission of the project is to demystify Math and Science for learners in the early school years by raising their levels of understanding and changing their attitudes towards Sciences and Mathematics. This is done by exposing learners to Family Math & Family Science activities on a regular basis in the classroom and integrating the activities into the curriculum.

A total number of 5112 learners from predominately rural communities in the Free State and Northern Cape provinces were actively involved in doing Math and Science activities during the first 3 terms of 2009. To achieve this, the CED trained 9 Subject Advisors to act as coordinators in their respective regions with the responsibility of training and supporting local teachers in the implementation of the progamme. One of the key elements of the success of the project is the fact that the CED also manufactures and issues the 134 participating teachers with sufficient training material like manipulatives and other activity material to be utilized in the classroom. Without the support of the sponsors, ABSA and SANRAL, the latter would not have been possible.

It is envisaged to include as many schools as possible in the Free State and Northern Cape province in the programme, depending on sponsorships received.
