Introducion • On full bright sun, the photocurrent is maximum. • The photocurrent is less on a partial sunny day. * On a cloudy day, the photocurrent is maximum. • The output voltage and current of the PV module vary with the intensity of solar irradiation as well as the angle made by the sun with the solar panel. Since the sun's angle in the sky influences the intensity * A photovoltaic solar panel produces electricity in direct proportion to the amount of sunlight falling on of the light received by the Earth, the location of the sun affects how much energy a solar panel generates. * When the sun is overhead, its rays are the most direct it. • The stronger the intensity of sunlight, greater will be and intense. the output energy. • As it becomes lower in the sky, the same area of light Apparatus required with Specifications from the sun covers a larger area of the Earth.
