Integration of biogas into the rural energy supply of solar home system powered households in South Africa: A case study of Tsware, Mailula and Muropo vilages in Limpopo.

Author: Tazvinga, Henerica ; Murambadoro, M ; Mapako, M Date: Oct 2011 This study indicates that it is technically feasible to combine solar home systems and biogas to meet the community's thermal needs, however more work needs to be done to arrive at the best possible financial implementation model. All ... Read more
Optimal dispatching of a photovoltaic-biogas hybrid system

Author: Tazvinga, Henerica Date: Aug 2018 This paper presents an optimal dispatching strategy for a photovoltaic-biogas hybrid system for an off-grid institution. The aim is to prioritise use of the PV system to meet demand whenever available. If the demand is less than the PV output, ... Read more
A sustainable operational method for micro-scale biodigesters in South Africa

Author: Semelane, Maphumzane S ; Tazvinga, Henerica ; Diakanua Nkazi, B Date: Aug 2018 This paper describes an investigation into sustainable operational methods for micro-scale biodigesters. The findings indicate a compulsory maintenance contract that ensures constant digester feeding for microorganism sustenance is essential. ... Read more
Technical model for optimising PV/diesel/battery hybrid power systems

Author: Tazvinga, Henerica ; Hove, T Date: 31 Aug 2010 A solar-based power supply system, such as a photovoltaic (PV)-diesel-battery system, is a particularly attractive option for decentralised power supply in southern Africa where solar radiation is ubiquitous in most countries. Such systems ... Read more
Women’s perceptions on the integration of solar powered home systems and biogas and its potential to improve gender disparities in energy

Author: Murambadoro, M ; Tazvinga, Henerica Date: Oct 2012 The extension of the national grid to rural areas has been hampered by several factors such as long distances, high costs of tension lines and the relatively low energy demand in rural areas which does not compensate the cost of long range ...
