For these reasons, monitoring that registers the DC production at least on the junction box level is strongly recommended. The availability of the monitoring data should be 99% or higher. Periods in which either data for irradiance or production is not available, should not be included in the analysis of the PV plant.
To analyze the profitability and the energy yield of a utility scale PV plant, the measurement of the generated energy at the revenue meter located at the connection point assigned by the utility would be sufficient.
The temperature of a PV module follows from its heat balance. As a linear approximation and neglecting the thermal capacitance of the module, the heat dissipated to the environment is proportional to the solar radiation received by the module. Moreover, the heat dissipated is proportional to the difference between module and ambient temperature.
