Dimentions

Surface

EPG BS
This is the surface area of the PV-panel excluding the support structure.

Orientation

EPG BS
The orientation of the PV-panel / solar collector is specified with respect to the north direction. The north direction corresponds to an orientation of 0 º and the south direction to an orientation of 180 º. A PV-panel/solar collector which has been oriented towards the south will give the most favourable yield. The orientation and the angle of inclination of a PV-panel / solar collector determine the amount of incident solar radiation as presented in BS 7120, Chapter 21, for different orientations and inclinations.

Angle of inclination

EPG BS
This parameter represents the angle of inclination of the PV-panel / solar collector. A horizontal surface has an angle of inclination of 0º, and a vertical surface has an inclination of 90 º. The most favourable angle of inclination is around 35 or 36 º. The angle of inclination and the orientation of a PV-panel / solar collector determine the amount of incident solar radiation as presented in BS 7120, Chapter 21, for different orientations and inclinations

EPG : To compute the shading reduction factor a minimal obstruction is assumed by default. This cannot be modified at the time.
