Characterization of solar photovoltaic modules in outdoor and indoor conditions

Author: Mkasi, Hlaluku W ; May, Siyasanga I ; Basappa Ayanna, Manjunath ; Pratt, Lawrence E ; Roro, Kittessa T Date: Oct 2019 This paper summarizes the results of solar photovoltaic (PV) module electrical characterization under outdoor and indoor conditions in the Republic of South Africa. Under outdoor conditions, the bi-facial PV modules on fixed racks and dual-axis ... Read more
The effect of soiling on the PV performance ratio for different PV systems

Author: Mienie, S ; Basappa Ayanna, Manjunath ; Pratt, Lawrence E ; Roro, Kittessa T ; Diale, M Date: Jun 2018 Soiling is an important and unpredictable factor that affects PV plant performance. Soiling is dependent on so many factors making it hard to quantify and accurately incorporate in PV prediction models and levelized cost of electricity (LCOE). ... Read more
Energy Storage

Author: Bladergroen, B ; Bischof-Niemz, T Date: Oct 2015 With the emergence of variable renewable energy (VRE) sources, such as solar photovoltaics (PV) and wind power, flexibility requirements in the power system are generally increasing. However, what is not so clear yet is what “increasing ... Read more

Integration of renewable energy and energy efficiency into high temperature applications

Author: Roos, T ; Surridge-Talbot, K Date: Oct 2015 Numerous economically important high temperature processes contribute to South African emissions; this is apart from the electricity generation sector which is responsible for half of South African emissions. Some are driven by fossil fuel ... Read more
A mini-integrated resource plan for a commercial entity in Gauteng Province: planning for energy autonomous businesses

Author: Senatla, Mamahloko ; Mushwana, Crescent Date: Aug 2017 Distributed renewable energy competitiveness is becoming a reality in most countries resulting in an increase of installed capacity in both developed and developing countries. Mexico, India, Germany, Zambia and South Africa have experienced ... Read more
A review of planning methodologies used for determination of optimal generation capacity mix: the cases of high shares of PV and wind

Author: Senatla, Mamahloko J ; Bansal, RC Date: Aug 2018 It is undeniable fact that energy systems all over the world are at the point of paradigm shift as a need for decarbonisation is eminent and unavoidable. The pressure to decarbonise mounts year after year. Since two thirds (67%) of all ... Read more
