The amount of solar irradiance falls onto photovoltaic (PV) panels depends highly on the tilt angle between the panels and the horizontal plane.Therefore, this angle must be chosen carefully so that the panels can absorb the largest possible amount of the solar beam.It is more convenient for the panels to be installed with the fixed tilt angle once
Noise exposure is one of the major occupational hazards in many places, and has several health effects, including hearing loss and psychological effects such as sleep disturbances and mental stress.The objective of this research was to determine the relationship between noise and stress and other risk factors that affect job stress.A cross-sectiona
