Abstract
A photovoltaic system includes: a plurality of solar cell modules each including a plurality of solar cells, at least one monitoring device configured to measure a module voltage of a corresponding solar cell module from among the plurality of solar cell modules, and a current measuring device that receives the measured module voltage from the at least one monitoring device and is connected to the plurality of solar cell modules through a power line to measure a module current of the plurality of solar cell modules.
Claims20
A photovoltaic system comprising:
- a plurality of solar cell modules each including a plurality of solar cells;
- at least one monitoring device configured to measure a module voltage of a corresponding solar cell module from among the plurality of solar cell modules;
- and
- a current measuring device that receives the measured module voltage from the at least one monitoring device and is connected to the plurality of solar cell modules through a power line to measure a module current of the plurality of solar cell modules.
A method of monitoring a photovoltaic system, the method comprising:
- measuring a module voltage of a plurality of solar cell modules;
- transmitting power generated from the plurality of solar cell modules and module data including the measured module voltage to a current measuring device;
- and
- measuring, by the current measuring device, a module current of the plurality of solar cell modules based on the received power.
A monitoring device for a photovoltaic system, the monitoring device comprising:
- a voltage measuring device connected to both ends of a plurality of solar cells included in a solar cell module to measure a module voltage of the solar cell module;
- and
- a communication interface configured to transmit module data including the measured module voltage to a current measuring device connected to the solar cell module.
