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.

Examination format at UFS to change
2011-04-22

A new examination format is to be followed from the coming examination in May 2011 at the University of the Free State (UFS). According to this, the additional examination opportunity is to follow on the heels of the main examination.

According to the new format, students who qualify to write examinations will be compelled to write their papers during the first opportunity, and will only be allowed to write an additional examination once their applications for this examination have been approved. Students who qualify for re-assessment and special examinations will automatically be admitted to the additional examination and will therefore be exempt from the application process.
 
According to Dr Saretha Brüssow, Head: Teaching and Learning at the UFS, the Examination Committee requested the investigation of the double examination which applied previously, due to the pressure it caused on the university systems.
 
She said that, besides this release of pressure on systems such as the registration process, the back-to-back semester-based examination system might also lead to a possible improvement of the academic success rate, due to the shorter time span between the first and the second examination opportunities.
 
Students attended classes poorly in the past due to the second examination opportunity, which took place during the following semester after classes had resumed. “In some cases it is specifically the student at risk, who cannot afford to miss classes, who makes use of the second examination opportunity.”
 
Dr. Brüssow said the registration process was also affected by the previous format due to students who wanted to receive their results first before they registered. Other delays which occurred as a result of the second examination opportunity, were the first annual graduation ceremony which took place late in the year, the awarding of bursaries, and the finalisation of residence accommodation. Adding on to this problematic nature is students who occupy residences in the following academic year without a formal application in order to write during the second examination opportunity in January.
 
The new format is applicable to all students, except those in the Faculty of Health. Main and South Campus students can direct enquiries to addexam@ufs.ac.za. Qwaqwa Campus students should email addexam@qwa.ufs.ac.za.  Information on the new examination format is also available on www.ufs.ac.za.
