Estimating the Optimum Tilt Angle of Solar Panels in Fujairah

A shift is taking place toward using renewable energy sources, with solar energy being one of the most prominent. The challenge with solar energy is that the power output is low or in other words, low efficiency. therefore, the sunbeam must be directed toward photovoltaics (PVs) to catch the maximum irradiance. The proposed solution is to use a MATLAB program to calculate the optimum tilt angle in Fujairah and the find the irradiance too, taking into account the location, day, declaration angle, and hour angle. also, by comparing the results found by our mathematical model with a real application called (PVWatts) which is developed by the NREL (US National Renewable Energy Laboratory) and by previous studies done before on the same topic. The results have been verified and the values are very similar.
