The demonstration discussed in this report illustrates the added value of the IRENA Global Atlas for initiating informed discussions on future solar developments in a region. The demonstration covers the ECOWAS region, with data sets supplied by ECREEE and involves a grid-connected and an off-grid scenario for solar photovoltaic, as a contribution to SE4All. The outcome of this demonstration will also be presented in the framework of the GEOSS AIP-6 and the results can be accessed as GIS layers at http://irena.masdar.ac.ae/?map=507.
