GeoSUN Africa specialises in specifying, installing and monitoring on-site solar and weather stations in sub-Saharan Africa for CSP, CPV and PV clients. We are currently managing 9 such stations for PV, CSP and CPV clients. CSP projects are mandated to conduct on-site solar measurements for at least one year under the South African REIPPPP programme. Although REIPPPP does not mandate PV developers to conduct on-site measurements, they are encouraged to do so if PV plants are above 5 MW. CPV is classified under PV in the requirements for the REIPPPP programme, and likewise, no on-site measurements are required. CPV developers are however strongly encouraged to install on-site solar measurements.
