Translations:Tilt and azimuth/2/en

The sunlight that reaches the earth is strongest when it strikes a surface perpendicularly (with an angle of 90°), yet the position of the sun in the sky varies through the day and through the year for every location. This means that to capture as much sunlight as possible and maximize production, a PV module must be properly positioned. There are two important ways in which a PV module can be positioned relative to the sun:

• Direction relative to the cardinal directions (North, East, South, West).
• Angle relative to the surface of the earth.
