NOVELTY - System of photovoltaic panels comprises triangular panels (51, 61) and rectangular panels (54, 64). The triangular panel has a right-angled triangular shape. The photovoltaic cells in the rectangular and triangular panels have the same electrical efficiency characteristics and short circuit current (Istc) and a maximum load current (Imax) equal for all the cells.    USE - System of photovoltaic cells for capturing solar radiation.    ADVANTAGE - The system uses a photovoltaic panel conformation which can be combined in all possible insulation situations that may be obtained over the course of the solar year in order to make better use of the surfaces available for their application, i.e., south facing surfaces on the roofs of buildings for maximizing the effect of light capture and system yield.    DETAILED DESCRIPTION - System of photovoltaic panels comprises triangular panels (51, 61) with cells in the triangular panel near the hypotenuse equal to the number of cells near each side and rectangular panels (54, 64) with a number of cells on the shorter side equal to the number of cells on the side with the triangular panels and a number of cells on the longer side equal to the number of cells on the shorter side plus one. The sides of the triangle are equal, i.e. the triangular panel has a right-angled triangular shape. The vertexes of each side and the hypotenuse are cut with short sides, which are also equal to each other, near the cell on the end of the row and with a right-angled direction with respect to the side. The photovoltaic cells in the rectangular and triangular panels have the same electrical efficiency characteristics as each other and short circuit current (Istc) and a maximum load current (Imax) equal for all the cells in the production batch and assembly in the system in order to have a no-load voltage.
