Abstract

The tendency today is oversizing the PV peak power compared to the inverter power. It makes sense in northern cloudy countries, but the question arises if something can be done with the excess power, mainly in summer? The harvesting of unused power can be made at low cost by using a dump resistor. It results in another type of “PV characteristic”, where the current gets lower at higher voltage, but it remains stable... READ MORE
