Solar Resource and PV Potential of the Maldives : Solar Model Validation Report (anglais)

This report describes accuracy enhancement of Solargis solar resource data for Maldives based on the ground measurements collected at four solar meteorological stations across the country. These solar meteorological stations were installed and operated by Suntrace GmbH company (Germany), and commissioned by the World Bank over the years 2015 to 2018 under the same activity. The data layers show long-term yearly and monthly averages of Direct Normal Irradiation (DNI) and Global Horizontal Irradiation (GHI), and they represent a period of the last 19 years, from 1999 to 2017. The data is calculated by aggregation of sub-hourly map-based time series calculated for the territory of Maldives with 1-km spatial resolution. The aggregated data layers are delivered in the format that is compatible with Geographical Information Systems (GIS). Additionally, printable maps are available in digital format and ready-to-use for large-format printing. The accuracy of the data layers is enhanced by the regional adaptation of the Solargis model with use of ground measurements acquired at four high-standard solar meteorological stations located in Maldives. The measurements helped to reduce systematic deviation of the data inputs to the Solargis model as driving factors of the accuracy in this region. Individual improvements of the Solargis model at the stations in Maldives are shown in the table below. As a result of the regional adaptation of the Solargis model, the calculated GHI and DNI data are more accurate and with reduced uncertainty.
