1REQUIRED INPUT

Enter the solar inverter size (Watts). The system size forms the basis of PV module string and solar array design recommendations.

2ASSUMPTIONS

Enter the open circuit voltage Voc (V) of the solar panels used in the system. Unlock the lock icon on top to change default values.

Enter the open circuit voltage’s temperature coefficient (%/°C) provided by the solar panel manufacturer. This is the percentage drop in power generation for every °C increase in the module temperature. Unlock the lock icon on top to change default values.

solar panels modules array Enter the minimum temperature (°C) at which the solar system is expected to operate and generate power.

Enter the solar energy panel wattage (Watts) provided by the solar panel manufacturer. Unlock the lock icon on top to change default values.

Enter the maximum input voltage to inverter (Vdc) provided by the solar inverter manufacturer. Unlock the lock icon on top to change default values.
