Mapping distribution of SA solar resources

February 13th, 2012, Published in Articles: PositionIT

GeoModel Solar, a leading international provider of solar resource data, online site assessment tools, and expert consultancy, has released a new set of solar maps for South Africa, Lesotho, and Swaziland. The abundant global and direct solar radiation is now mapped in the best possible quality, which will support the development of photovoltaic and concentrated solar energy in the country. Marcel Suri, Managing Director of GeoModel Solar says the uniqueness of these maps is reflected in their very high spatial resolution of 250 m. The solar radiation received in some regions can vary by up to 20% within a distance of 10 km. Hence, it is very important to have access to data with high accuracy and spatial resolution, making it possible to predict a solar plant’s output with greater confidence. High reliability of maps was achieved thanks to the use of data from SolarGIS, the most accurate solar resource database available for Southern Africa. SolarGIS, developed by GeoModel Solar, has been extensively validated by a number of local ground measurements in partnership with Centre for Renewable and Sustainable Energy Studies, Stellenbosch University. The maps and data can be accessed through the SolarGIS web-based platform:
