Solar Cell I-V Characteristic Curves

The above graph shows the current-voltage ( I-V ) characteristics of a typical silicon PV cell operating under normal conditions.

Solar Panel Orientation

Installing solar panels orientated directly east or west will typically only have a drop off in generation of about 25% compared to that of a south facing array. However, there is an argument to say that installing a system with an east and west split (e.g. 2kWp facing east and 2kWp facing west) can potentially have benefits over a system orientated due south.
