Technical and economical evaluation on the use of reconfiguration systems in some EU countries for PV plants

This paper shows the technical and economical evaluation of the application of a reconfiguration system for photovoltaic (PV) plants, considering the incentives system in some European Union countries. The reconfiguration system is an alternative to the distributed maximum power point tracking technique which used to increase the power production in the PV plants under the mismatch phenomenon. The reconfiguration techniques employ a microprocessor-based or field-programmable gate array-based system that modifies the layout of the PV plant through the change of the connections among modules. After having presented the main features working of the PV reconfiguration system allowing the improvement of the efficiency of the same plant and the relevant installation, the main strength and weakness points of the investment are evidenced in relation to different incentives policies in some country of UE
