SOLAR <strong>RADIATION</strong> ON TILTED SURFACE<br />

The power incident on a PV module depends on:<br />

•the power contained in the sunlight<br />

•the angle between the module and the sun.<br />

The power density will always be at its maximum when the PV module is<br />

perpendicular to the sun<br />

However, as the angle between the sun and a fixed surface is continually<br />

changing, the power density on a fixed PV module is less than that of the<br />

incident sunlight.<br />
