Question

If the orientation of pv module changes from horizontal to vertical tilt angle will be

Answer 1

       The tilt angle depends on many factors.

• PV panels collect solar energy from sun and convert them into electricity.
• To get maximum efficiency we need to tilt the pv panels in such a way so that it can get maximum sunlight.
• The panel collect maximum when the sunlight is perpendicular to the panel surface.  
• The angle of the sun varies throughout the year, so the tilt angle for summer is different from winter.
• Even the latitude and longitude of a geographical region is important deciding the tilt angle.
