Solar resource mapping in Malawi : model validation report (Inglês)

This Model Validation Report shows method and results of preliminary validation of solar resource and meteorological data for the Republic of Malawi, Phase 1 of solar resource mapping and measurement services. The project is a part of technical assistance in renewable energy development implemented by the World Bankin Malawi. It is being undertaken in close coordination with Ministry of Natural Resources, Energy and Mining of Malawi, the World Bank’s primary country counterpart for this project. The project is funded by the Energy Sector Management Assistance Program (ESMAP), a global knowledge and technical assistance program administered by the World Bank and supported by 11 bilateral donors. It ispart of a major ESMAP initiative in support of renewable energy resource mapping and geospatial planning across multiple countries. This report documents validation of solar resources calculated by satellite model SolarGIS, and meteorological data derived from the CFSR and CFSv2 models. Inventory in Chapter 3 identifies the existing data sources inthe region: solar, aerosol and meteorological data. First, aerosol (Atmospheric Optical Depth, AOD) data fromthe MACC-II model is evaluated (Chapter 4, this data is used on the input to SolarGIS clear-sky model). Chapter 5 shows relative comparison of SolarGIS GHI and DNI to other modelled databases. Next, validation to high-quality solar resource measurements demonstrates stable performance of SolarGIS in geographic conditions, similar to Malawi. Chapter 6 validates meteorological parameters that are used for site-specific dataand for maps. Chapter 7 summarizes validation results in the estimate of uncertainty. Validation demonstrates stable performance of SolarGIS model in Africa. The validation and previousexperience indicate that using high-quality local measurements, the Solar GIS model output have significantpotential for reduction of uncertainty in geography of tropical Africa.
