There methodologies also calculate the angle of inclination of the panels and other system components. A review of several articles by Grassi et al, aims to assess the performance of the photovoltaic system and day lighting system in sustainable buildings. The methodology to measure the efficiency of each system, considers aspects such as the selection of the type of panel used, the orientation of the building, the installation location, the area of the installtion, and the tilt angle. However, Fadee and Radzi provides an overview of multi-objective methods using evolutionary algorithms to solve optimization problems with respect to the positioning, sizing, design, planning and control, in order to increase reliability of renewable energy hybrid systems in remote areas.
