Abstract:
The condition of the Solar Photovoltaic (PV) systems should be monitored continuously for obtaining better performance and timely maintenance. PV systems installed at different locations with monitoring capabilities provide information in advance about performances. Based on this information, maintenance can be carried out to improve the performance and life cycle of the system, thereby also reduce overall operating cost. Quality of several monitoring systems for local and remote application, based on the techniques of communication, such as, computer to computer, embedded system to computer (GSM) and embedded system to embedded system (GSM, GPRS). In different locations solar radiation, solar day, latitude, geographical zone are also different with sun earth astronomical relation. For getting peak data and actual data is differing with weather condition and seasonal basis. It is difficult to measure correct data by conventional monitoring system. Those monitoring techniques are sometimes unable to collect required data for long time and at specific time duration. A new technique is proposed as a solution to overcome the limitations of other techniques. The proposed technique uses distributed Point to Point (P2P) communication (Ethernet), for the collection of data, with a standard supervision graph and data server. A dedicated computer server will collect actual data with distributed P2P connection and will store in server’s database view as a graph and data sheet. In order to study and evaluate the performance of proposed technique, measures actual data values. By the technique we can easily get hourly, daily, monthly and yearly performance data of a PV system.
