Three-Year Performance Evaluation of Single Junction Amorphous Solar Cells Grid-Connected Power Station in Libya

الملخص EN

Photovoltaic (PV) conservation of solar energy is one of the most promising sources of future energy.

Grid-connected PV systems are widely used in many countries, but in Libya it is just started.

A PV grid-connected of 24 KWP PV system has been installed as a pilot project to deliver AC energy to the Tripoli University electric grid; the system is of single junction amorphous solar cells which were erected in Sep.

2009; it consists of 240 Mitsubishi thin film amorphous PV Modules of MA100T2 type capable of supplying 100 Watts of DC power each, five inverters of type SMA Sunny Mini Central, and the system is equipped with a data logger to record all important parameters.

In this paper the evaluation of the PV system performance was carried out according to the European guidelines of the PV system operation.

The results of the measured parameters, namely, the performance ratio, AC energy yearly yield, the temperature dependent, and the system efficiency, showed that the system is performing better than the deigned parameters.
