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.

New infrastructure development project planned for the Bloemfontein Campus

The university community can look forward to two new infrastructure development projects on the Bloemfontein Campus. The construction of a new parking area for staff and students accommodated in the new Education Building, will begin as early as June 2015.

The project includes 113 parking places for students and 16 covered parking places for staff. According to Nico Janse van Rensburg, Senior Director at University Estates, the project will be tackled using several green approaches. “The parking area’s lighting will be solar-powered. The surface will not be the normal paving stone but will permit the water to drain into the ground and in this way be more environmentally friendly and minimise the greenhouse effect,” he says.

Several indigenous trees will beautify the area.

The new parking area will be situated opposite the UFS Sasol library’s student parking area, between the cricket field and the present parking area at the Education Building.

The second project involves a new roof structure at the Bloemfontein Campus’s main entrance security gate.

Since August last year, the university has been enforcing rigorous entrance controls. No person can access any of the five entrances of the Bloemfontein Campus without a valid entrance card. Should individuals not have a card, they must access the campus at Gate 5 in DF Malherbe Avenue where a temporary access card will be issued to them.  Scanning for visitors and service providers is also available at Gate 1 (Nelson Mandela Drive) and Gate 5 (DF Malherbe Avenue).

The  roof structure at the main entrance will serve as a security point. Primarily, it will provide shelter from the elements for those staff manning the area.

Nico says that the plan is to complete the projects before the end of the year. The projects are currently in the planning phase.

“The gate may possibly be closed for a day or two but the main work will be done during weekends. Certain lanes may also be closed from time to time to ensure the safety of both users and construction workers,” says Nico.

Staff and students will be advised well in advance if and when the gate will be closed.
