The electricity rationing occurred in 2001 due to lack of rain, led the country to increase the participation of alternative energy sources. This need for new sources of energy makes the regional potential to be exploited, which configures the change of generation model from centralized generation to distributed generation. Among the alternative sources of energy, the solar energy is presented as very promising for Brazil, given that most of its territory is located near to the equator line, which implies days with greater number of hours of solar radiation. The state of Rio Grande do Norte (RN) has one of the highest levels of solar irradiation of the Brazilian territory, making it eligible to receive investments for the installation of photovoltaic solar plants. This thesis will present the state-of-the-art in solar photovoltaic power generation and will examine the potential for generation of solar photovoltaic power in Brazil and RN, based on solarimetrics measurements conducted by various institutions and also measurements performed in Natal, the state capital / A gera??o de energia el?trica no Brasil ? predominantemente renov?vel, com a gera??o interna hidr?ulica sendo superior a 70% do total de sua matriz energ?tica. O racionamento de energia el?trica ocorrido em 2001, devido ? falta de chuvas, levou o pa?s a incrementar a participa??o de fontes alternativas de energia. Esta necessidade por novas fontes de energia faz com que as potencialidades regionais sejam aproveitadas, o que configura a mudan?a do modelo de gera??o, passando de gera??o centralizada para gera??o distribu?da. Dentre as fontes alternativas de energia, a solar apresenta-se como uma fonte bastante promissora para o Brasil, tendo em vista que a maior parte do seu territ?rio est? localizada pr?ximo ? linha do equador, o que implica em dias com maior quantidade de horas de radia??o solar. O Estado do Rio Grande do Norte (RN) tem um dos maiores ?ndices de incid?ncia solar do territ?rio brasileiro, o que o torna apto a receber investimentos para a instala??o de usinas solares fotovoltaicas. Esta disserta??o apresentar? o estado da arte em gera??o de energia solar fotovoltaica e analisar? o potencial de gera??o da energia solar fotovoltaica no Brasil e no RN, baseando-se em medi??es solarim?tricas realizadas por diversas institui??es e tamb?m em medi??es realizadas em Natal
