The variation of solar cell Vocduring irradiation may alsobe empirically characterised by an expression similar to thefirst equationfor Isc: Voc= Voc0- C'log (1 + Phi/ Phix) . In general, the open circuit voltage of a silicon solar cell can be representedas: Voc= kT/qln (1 + Isc/ I0) .
The irradiation on the PV modules is calculated from the climate data, which usually contain the ambient temperature and the solar irradiation in hourly resolution. This requires a series of partial steps: Calculation of the geometry of module area and angle of irradiation (tracking)
The direct component of the solar radiation is determined from the air mass: I D = 1.353 × 0.7 (A M 0.678) The airmass can be determined from the Air Mass formula: A M = 1 cos θ
The data provided by PVGIS contains both irradiance and irradiation values. There is little doubt that the very best way to measure solar radiation is to use high-quality sensors on the ground. But to be useful, these measurements should fulfill a number of conditions: Only high quality measurement sensors should be used.
The first step for simulating photovoltaic systems is modeling the irradiation. The irradiation on the PV modules is calculated from the climate data, which usually contain the ambient temperature and the solar irradiation in hourly resolution. This requires a series of partial steps:
Calculate the power for every value of voltage and current by using the equation below. P = V × I Thus, by using these measured values all the other parameters of the PV module can be obtained.
