Abstract

MARQUES, Derivan Dutra; BRITO, Alaan Ubaiara; CUNHA, Alan Cavalcanti da  and  SOUZA, Leandro Rodrigues de. Variation of the solar radiation over the Amapa state: a case study on Macapa, Pacui, Serra do Navio and Oiapoque during the period from 2006 to 2008. Rev. bras. meteorol. [online]. 2012, vol.27, n.2, pp. 127-138. ISSN 0102-7786.  http://dx.doi.org/10.1590/S0102-77862012000200002.

The objective of this study was to estimate the potential of solar energy through the variation of the global solar radiation (GSR) in the State of Amapá during two season's cycle (2006 to 2008). GSR historical time series were used from four collection data platforms (PCD's) distributed in a central area of the state. The results indicated that the distribution of RSG showed annual peak of about 4900Wh.m-2.day-1 on the Macapá station, due to its proximity to the equator line. At Serra do Navio, Pacuí and Oiapoque cities the values observed were 4000, 4400 and 3800Wh.m-2.day-1, respectively. We conclude that the studied sites in Amapá State have significant potential for photovoltaic use during a complete annual cycle. The potential for generating electricity proved to be attractive, both for use in traditional urban systems and in isolated systems in remote communities.
