Online Distributed Measurement of Dark I-V Curves in Photovoltaic Plants

Multi-channel recorder for I-V curves

The operation of nine – channel microprocessor controlled recorder to be used for concurrent recording of current – voltage characteristics in two or three electrode configurations has been described in the present study. The prototype version of the recorder as been designed for measurements associated with determination of oxygen stream density in the course of soil oxygen micro-diffusion. Th...

Energy Storage in Grid-Connected Photovoltaic Plants

Nowadays, photovoltaic (PV) plants are receiving a very great attention due to their intrinsic ability to directly transform solar energy in electrical energy. Nevertheless, electricity generated from photovoltaic plants can rarely provide immediate response to load demand, as these sources do not deliver a regular supply immediately compatible with consumption needs. In stand-alone PV plants, ...
