In this paper, we are concerned about optimal tilt angle choice of solar panels installation in three cities in Albania. The optimal tilt angle of solar panels is a crucial parameter for a high performance of solar energy systems. Solar energy systems can be tracking systems or fixed systems, fixed tilt angle determination and adjustable tilt angle evaluation of solar panels is an important issue to solve. In this study, Bernard-Menguy-Schwartz (BMS) model is used to determine the yearly and seasonally optimum tilt angle of the solar panels in three cities in Albania. The determination of the optimum tilt angle is made considering the fact that the solar energy reaching the solar panels has maximum value for optimum tilt angle. The yearly optimum tilt angle of the solar panels for the cities: Tirana (41.3275° N, 19.8187° E), Kuksi (42.0807° N, 20.4143° E) and Vlora (40.4661° N, 19.4914° E) are respectively 38o, 39o and 37o. It should be noted that, the yearly optimal tilt angle of solar panels based on the above mathematical model is almost equal to the latitude of the location. A suggestion of seasonably adjustable tilt angle is made. In addition, seasonally or adjusted tilt angles of solar panels were compared with yearly optimal tilt angle.

The power generation of a photovoltaic (PV) system is significantly influenced by the tilt angle of the module. The system achieves the highest power efficiency when operated at the optimal tilt angle, which is typically considered in the design of system installation. In this study, the optimal tilt angle of photovoltaic (PV) modules is determined by using PVsyst software and analyzed through shadow simulation under specific boundary conditions. The study examines the power generation of photovoltaic (PV) panels at various inclination angles and illustrates the impact of inclination angle on PV panel power generation by using project-specific data. The study results indicate that the secondary optimization of the tilt angle by PVsyst, in conjunction with the geographic factors of a specific region in Hainan, reveals that the optimal installation tilt angle for maximum power generation benefit is 9°. This finding aligns with the best power generation and benefits from the actual installation, which is at 10° (adjacent to 9°). The conclusions drawn from the exploration emphasize the essential nature of EPC optimization for future projects, as it can serve as a valuable reference for the design of photovoltaic power generation systems.

Solar energy is the most abundant renewable energy source. This energy can be converted directly into electricity using solar panels. The fixed tilt solar panels are the most practical and the most widely installed throughout the world. Optimum tilt angle calculation has the advantage that it does not use expensive solar trackers. This research calculates the seasonal optimum tilt angle of solar panels for 17 cities in Iraq and 83 cities in 83 countries distributed around the world. Solar Panel Angle Calculator program was used in calculating the optimum tilt angles from vertical. The optimum tilt angle varies between 6° and 112° throughout the year. This angle for winter, spring/ autumn and summer seasons are found to be between 6° to 66°, 30° to 89° and 54° to 112°, respectively. All angles calculated from the calculator program are validated by comparing it with those obtained from equations. An excellent agreement was established. Cities which have approximately the same absolute values of the latitudes are have the same optimum tilt angles. Based on the results, adjusting angles four times a year is recommended. This work can serve as a guidance for installing solar panels.
