“…Despite some success, as noted by van der Merwe and Brent (2020) [10], where over 2900 megawatts of renewable energy have been commissioned through privately funded projects worth approximately 13 billion US Dollars, the government's slow policy implementation for integrating independent energy sources into the grid raises uncertainty among investors. This lack of clear policy and approach in the renewable energy sector, as highlighted by Kannan and Vakeesan (2016) [11], has rendered the field less appealing. This underscores the importance of enhancing methods, data, and analytical techniques for energy assessments like the Photovoltaic Geographical Information Systems (PVGIS) [12].…”

“…South Africa's "favorable" geographic positioning implies that it may have great potential in using solar energy. Through the development of geodatabases built upon years of remotely sensed data on solar energy, a web-based tool-PVGIS, (version 5.2) presents capabilities of monitoring and assessing the solar potential of different locations [11,14,15]. In this regard, this research attempts to compare and assess the regional potential of solar energy between the two provinces, using data from the PVGIS tool and the Kriging technique, to study how the mentioned provinces could be suited for future solar technologies.…”

South Africa has committed to reducing its greenhouse emissions by sixty-five percent by 2030 in their National Integrated Energy Plan (NEIP). The lack of investment and development for renewable energy sources put the country on an uncertain trajectory in fulfilling its 2030 energy commitments. At the same time, the country has been labeled as a region with one of the highest solar energy potentials. Provinces such as Mpumalanga and Northern Cape are on opposite ends of the matter, with Northern Cape is one of the leading provinces for renewal energy, while the Mpumalanga province remains the host to eighty-five per cent of the country’s coal plants. Solar energy is an abundant renewable energy source and can be assessed using Geographic Information Systems (GIS) techniques. In this paper, the geostatistical technique, Kriging, is employed to predict, estimate, and compare the regional distribution, potential, and variability of annual optimum solar energy (irradiance) between the Mpumalanga Province and Northern Cape Province. Spot-based radiation data are available for solar energy analyses from the GIS Web-based tool Photovoltaic Geographical Information Systems (PVGIS). Kriging was used to estimate the spatial variability of solar energy at an average error of 1.98505% for the Northern Cape Province and 2.32625% for the Mpumalanga Province. It was identified that the Northern Cape receives the highest annual optimum irradiation and has a low overall spatial variation in irradiation over its provincial area. Mpumalanga receives lesser amounts of irradiation but has high overall spatial variation over its provincial area. Most of Northern Cape’s central to northwestern regions have the highest annual optimum irradiation ranging from 2583 kWh/m2 to 2638 kWh/m2, while Mpumalanga’s highest regions of annual irradiation occur primarily on its western and northwestern parts and ranges in highs of 2345 kWh/m2 to 2583 kWh/m2.

Rural Households’ Perceptions of the Adoption of Rooftop Solar Photovoltaics in Vhembe District, South Africa

2022

View full text Add to dashboard Cite

Rooftop solar photovoltaics have the potential to successfully electrify rural and scattered communities worldwide. However, access to clean, high-quality, reliable and affordable energy remains elusive for several households in rural areas of the developing world. To fully comprehend, unpack and proffer meaningful solutions to this mismatch, energy sources in use and types in areas where rural electrification through solar home systems are profiled. Furthermore, grassroot communities’ perceptions of rooftop solar photovoltaics (PVs) was explored. A case study design was adopted. Thirty (30) households were purposively sampled from three selected villages. Their perceptions on the adoption of solar photovoltaic home systems were analysed qualitatively using Atlas ti 8 software. Thematic network analysis was pursued. Households in the chosen villages use grid connections, paraffin, solar PV, firewood and candles to meet their energy needs. The chosen villages used energy for water heating, refrigeration, cooking, illumination, space heating, entertainment and ironing at the household level. In general, the participating households perceived solar PVs as a relatively cheap, easy-to-use, environmentally friendly alternative energy, and did not demand regular payments once installed. However, there was a discerning perception that solar was a weak technology that could not be relied on because it produces an inferior quality of energy, could be easily stolen and needed high capital investment beyond the reach of many consumers. The results obtained in this study highlight that the solar home system (SHS) rollout should be sensitive to rural communities’ financial situations and be innovative in that low-income households are included. In addition, there is a need for a robust awareness programme that highlights the energy availability, reliability, quality, cost effectiveness and legal, health and safety benefits of the SHS to the rural families in the district.
