Effect of tilt angle on the performance and electrical parameters of a PV module

What is it about?

The present article aims to investigate the effect of varying module tilt angle on the PV cell temperature and its electrical parameters at the laboratory environment and compare the results with those monitored at Malaysian outdoor conditions with a view to set an optimum tilt angle for best performance.

Why is it important?

Indoor and outdoor investigation on the effect of tilt angle on PV performance. • 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.
