                         photovoltaic (PV) systems, solar PV generation in many sunny 
                         regions in Brazil will eventually become cost competitive with 
                         conventional and centralized power generation. Detailed knowledge 
                         of the local solar radiation resource becomes critical in 
                         assisting on the choice of the technology most suited for 
                         large-scale solar electricity generation. When assessing the 
                         energy generation potential of non-concentrating, fixed flat plate 
                         versus concentrating PV, sites with high levels of direct normal 
                         irradiation (DNI) can result in cost-competitive electricity 
                         generation with the use of high concentrating photovoltaic systems 
                         (HCPV). In large countries, where the transmission and 
                         distribution infrastructure costs and associated losses typical of 
                         centralized generation must be taken into account, the distributed 
                         nature of solar radiation should be perceived as a valuable asset. 
                         In this work we assess the potential of HCPV energy generation 
                         using satellite-derived DNI data for Brazil, a large and sunny 
                         country with a continental surface of 8.5 million km(2). The 
                         methodology used in the study involved the analysis of global 
                         horizontal, latitude-tilt, and direct normal solar irradiation 
                         data resulting from the Solar and Wind Energy Resource Assessment 
                         (SWERA) Project, and an estimate of the resulting electricity 
                         production potential, based on a review of HCPV generators 
                         operating at other sites. The satellite-derived solar irradiation 
                         data, with 10 km x 10 km spatial resolution, were analysed over 
                         the whole country, in order to identify the regions where HCPV 
                         might present a considerable advantage over fixed plate PV on an 
                         annual energy generation basis. Our results show that there is a 
                         considerable fraction of the national territory where the direct 
                         normal solar irradiation resource is up to 20% higher than the 
                         latitude-tilt irradiation availability. Furthermore, these sites 
                         are located in the most industrially-developed region of the 
                         country, and indicate that with the declining costs of this 
                         technology, distributed multi-megawatt HCPV can be a good choice 
                         of technology for solar energy generation at these sites in the 
                         near future.",
