Influence of tilt angle on PV output for solar energy optimization in Iraq

It has been established through investigation that the optimal inclination of photovoltaic (PV) modules is a critical factor for harnessing the maximal quantity of solar radiation impinging upon solar arrays. The specificity of the requisite angle for each site is underscored, contingent upon the solar trajectory over daily, monthly, and annual cycles. The determination of this optimal angle is imperative for maximizing the yield from solar PV systems within the confines of Iraq. Worldwide locales have seen the application of varied methodologies for ascertaining the correct tilt angle. The efficacy of PV systems is observed to be significantly influenced by whether a fixed or a tracking system is employed to modulate the tilt angle. The present manuscript delineates the contemporary state of research and praxis pertaining to the influence of tilt angle on PV output, employing an array of optimization techniques. Furthermore, the work offers a disquisition on the determination of the most advantageous tilt angle to optimize energy acquisition in Iraq. The inquiry reveals that an optimal tilt angle for Iraq is discerned to be 38.3. This compendium is intended to augment the compendium of knowledge available to designers and scholars endeavoring to pinpoint the most favorable tilt angle for solar PV systems in any given Iraqi locale.
