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.

Prisca Odero awarded ASA Presidential Fellowship

Dr Prisca Odero, a Centre for Africa Studies (CAS) fellow, received the African Studies Association (ASA) Presidential Fellow award in Indianapolis, USA, recently.

She was nominated for ASA by Dr Cyril Obi from the Social Science Research Council (New York), and was selected competitively, based on her PhD thesis and applied research work in rural development in Africa. Odero obtained her PhD in Africa Studies from the UFS at the July 2014 Graduation Ceremony.

On 22 November 2014, Dr Odero gave a public lecture at the Brooklyn College of the City University of New York. The event was hosted by the Political Science Department at the College.

Her paper, titled Sources and role of social capital in smallholder agricultural production: The value of membership of community groups to Zimbabwe rural livelihoods, sought to address the question of whether social capital contributed to the resilience of rural households in the face of economic difficulties and food security challenges. Dr Odero argued that the link between social capital and agricultural production is manifest in the ways in which farmers use social capital derived from membership of groups to alleviate agricultural production challenges.

Smallholder farmers in Zimbabwe, who face constraints in acquiring the necessary resources for production because of failing markets and reduced agri-industry productive capacity, employ a range of methods to deal with these challenges.  She presented an analysis of data collected through focus group discussions with representative groups and through a household survey.

Dr Odero’s research forms part of a book project. While books on agricultural development knowledge do exist, more studies analysing issues and offering solutions from an African perspective would help to address the gap in African knowledge production.
