Abstract
The presence of photovoltaic plants in the state of Maranhão is still timid when compared to other states in the federation. However, the photovoltaic power generation model has a great prospect of growth to next years. Studies to identify the regions of the state that are more favorable to installation of solar energy contribute for the managers of the power generation industry to make more rational decisions about the viability of their investments. This work deals with a feasibility study for the installation of solar photovoltaic plants covering the entire territory of the state of Maranhão using the multicriteria method (AHP) to weight the parameters or variables that can impact significantly the investment decision-making process. The parameters chosen for this study were: global solar radiation, normal separation and maximum temperature, power grid, road network, conservation units and indigenous territories. The data were normalized and standardized using the Quantum Gis software (QGis), which allows working with the Geographic Information System (GIS). Then the weighting matrix between pairs of criteria (judgment matrix) and the consistency ratio were calculated to ensure that the weights adopted in the peer relationships are consistent. The weights were used to weight as their only criterion layers and added up as information from the layers, multiplying by the restriction layer. A new layer of information was obtained, values varying from 0 to 0.795, which identify throughout the territory of the state of Maranhão, which regions are most suitable for the installation of solar plants. This new layer of information allows to order the most recommended places for investment in this business model, considering the criteria adopted.
