| Popis: | 8th World Conference on Photovoltaic Energy Conversion; 1596-1599 Photovoltaic technology becomes interesting in Serbia from household prosumers, to small business sector entities up to large utility scale plants have been planned and built due to real economic reasoning in the time of disruption of typical fossil fuel energy agendas. In order to meet the expectations of investors, which is increasingly important after the feed-in period is over, the more measurement, monitoring and validation of onsite production are needed. Therefore, a solution based on real-time monitoring of the photovoltaic plant has been designed and realized based on existing Internet of Things platform. The device allows those real-time measurements of each photovoltaic panel string current, voltage and temperature, together with onsite environmental and weather data to be routed by the gateway to the distant cloud server for the advanced processing. Advanced processing is important to diagnose the possible underperformance of photovoltaic plant by calculating indicators such as performance ratio, and weather corrected performance ratio. Such underperformance from temperature factor has been confirmed at the rate of ±2%. Further research will be directed towards inclusion of broader reasoning behind underperformance as a tool to maximize investors assets. |
