  • The developed monitoring system enables system degradation to be identified via the calculation of the residual difference in power generation between the computer model and the actual PV power plant. and irradiance, temperature and system output power are gathered from a 28.8kW grid connected solar power system.
  • Mathematical model consists of a photo current, diode, series resistor and a parallel resistor.
  • The photocurrent is directly proportional to the light falling on the cell. During darkness, the solar cell is not active; it works as a diode. It produces either voltage or current.
  • The major inputs for the proposed PV model were solar irradiation, PV panel temperature and PV manufactures data sheet information. In this study, the Astronergy HSM6610P225 PV module is taken as example.
  • With increased solar irradiance there is an increase in maximum power output and short circuit current.
  • with an increase in the cell temperature, maximum power output decreases whilst the short circuit current increases.
