Global Horizontal Irradiance kWh/km2 Malawi 0.5km 1994-2014 WBG

Global Horizontal irradiance (GHI) is the total solar radiation received by a surface horizontal to the ground. This value includes both the direct normal irradiance and the diffuse horizontal irradiance, and is of particular interest to photovoltaic installations; these data were created by GeoModel Solar.The map is an un-validated, satellite-derived estimate. As part of phase II of the WBG initiative, these maps will be validated through the use of ground measurement data, and until the data collection period is finished should be considered for policy use, rather than energy prospecting, following IRENA's classification of renewable energy data.
