Satellite-derived solar resource maps for Myanmar

Janjai, Serm; Masiri, Itsara; Laksanaboonsong, Jarungsaeng - In: Renewable Energy 53 (2013) C, pp. 132-140

Solar resource maps for use in solar energy applications have been produced for Myanmar. A satellite-based solar radiation model, originally developed for the tropics, was improved and applied for the region. A 13-year period (1998–2010) of imagery data from GMS 5, GOES 9 and MTSAT-1R...
