1 2017 1 SEI 190 33 1MW PLC Power Line Communication SSMAP While an increasing number of megawatt solar power plants have been constructed, some of them have already been facing problems with a degradation in power output due to initial failures, aging solar panels, or external factors. We have developed a string monitoring unit that uses power line communication (PLC) technology. These units monitor individual strings of hundreds of thousands of solar panels in real time without the need for connecting additional cables.
2 We installed the units at a megawatt solar power plant, and successfully detected irregularities in power generation by analyzing data collected from the units.
