By the way, during the research several case studies selected from both hot and cold climates will be observed, researched and calculated in order to find the best design principles for PV panel designs. So, comparative design method is selected to compare cold climate PV panel designs with hot climate PV panel designs. According to the findings, before designing the PV panel to the roof or facade or to the site, it is the most important to know the latitude of the place. The reason is to find the correct optimum tilt angle. According to the investigations, tilt angle that is known as inclined angle of the photovoltaic (PV) panel, is changeable due to the location of place, climatic conditions and the solar radiation. In Cyprus, tilt angle is 20 ° in summer and 50 ° in winter. On the other hand, if the panels designed fixed in North

The annual performance was predicted using a Fortran computer subprogram constructed based on the analysis and connected to the TRNSYS simulation program. The subprogram was experimentally verified at different meteorological conditions and design parameters in a previous study by the authors based on the meteorological conditions of Cairo (Egypt). It is found that the optimum value of yearly maximum output energy (i.e. the yearly output energy at the maximum power point) can be obtained from PV modules oriented facing south with a tilt angle in the range of 20–30°. Besides, the yearly maximum output energy of the PV modules mounted at different tilt angles and orientations is obtained as a fraction of its optimum value at the optimum tilt angle and orientation.
