The PV panel performance to generate electrical energy depends on many factors among which tilt angle is also a crucial one. Among hundreds of research work performed pertinent to solar PV panels performance, this work critically reviews the role of tilt angles and particularly locating the optimum tilt angle using different methods.
Experimentally fixed optimum tilt angle of 15° for real-time Malaysian conditions. Every 5° change in tilt cause a cell temperature drop by 2.70°C at outdoor. PV electrical parameters emanate significantly low at indoor conditions. Photovoltaic (PV) system's performance is significantly affected by its orientation and tilt angle.
In the previous review, articles on PV panels focus were made on temperature and other ambient conditions without paying attention to approach of study. Hence, these articles bring out the information on finding the behavior of PV panels with tilt angles adopting these three techniques.
As the PV panel performance is found to be affected by number of parameters, their consideration in any single study is not reported. In future, wor k is required to carry out the location of optimum tilt angle. As a whole, the optimum tilt angles reported for locations exactly on the equator line, i.e., 0°
