Performance coefficient can be defined as the conversion coefficient of radiation to usable energy in Solar Power Plants. We can list the main factors that affect this rate as follows:
Field Location (Temperature, wind etc.)
Losses (Inverter, dust, shading etc.)
Project and Design
Quality of Care
Irradiation on site, PV string temperature and values of energy meter are collected and delivered to web server through a microcomputer in according to IEC 61724 Standards.
Performance coefficient, real-time and estimated power production can compared. With this comparison, it is possible to calculate operational efficiency and awareness of faults that can cause performance loss.
