The paper proposes a new methodology for the output optimization of solar panels, by increasing the amount of available solar irradiation. The connection and relationship between the orbital positions of the Earth around the sun offer the possibility to force a mathematical model for the available solar irradiation at different times and angles. By using this model, the optimal path for the solar panel to take year-round can be calculated in an offline medium. This approach differs from the already existing solutions, by shifting the computational weight into an offline environment where the optimization work is performed. This is combined with a second-order optimization meant to limit the number of activation instances of the positioning system, thus obtaining optimal irradiation with minimal waste. Using the trajectory thus created the use of low-power and low-cost controllers will be enabled and the commercial viability of systems with 2 degrees of freedom will be increased. The performances of the proposed method are validated in simulation, using the MATLAB/SIMULINK environments.
