This study focuses on improving the energy conversion performance of photovoltaic panels in the Philippines with monthly and quarterly tilt angle adjustments. The study employs a mechatronic approach to verify the performance of PV systems. A mathematicalmodel is used to estimate the daily extraterrestrial radiation received by a unit area in order to generate the optimal PV tilt angles in the Philippines. The simulation results proves that it is worth changing the tilt angle of a PV panel facing true south on a monthly and quarterly basis in order to achieve significant irradiance gains over panels fixed at the computed optimal year tilt. Experimental results show that energy gains of up to 10% over a year period could be achieved using this technique.
