An individual silicon solar cell has a voltage at the maximum power point around 0.5V under 25 °C and AM1.5 illumination. Taking into account an expected reduction in PV module voltage due to temperature and the fact that a battery may require voltages of 15V or more to charge, most modules contain 36 solar cells in series.
You have learnt previously that the power output of a photovoltaic solar cell is given in watts and is equal to the product of voltage times the current (V x I). The optimum operating voltage of a PV cell under load is about 0.46 volts at the normal operating temperatures, generating a current in full sunlight of about 3 amperes.
Typical PV module produces power with maximum power voltage of around 17V when measured at a cell temperature of 25°C, it can drop to around 15V on a very hot day and it can also rise to 18V on a very cold day.
The voltage from the PV module is determined by the number of solar cells and the current from the module depends primarily on the size of the solar cells. At AM1.5 and under optimum tilt conditions, the current density from a commercial solar cell is approximately between 30 mA/cm 2 to 36 mA/cm 2.
PV module efficiency is the ratio of the electrical power output Pout, compared to the solar power input Pin, hitting the module. Pout can be taken to be PMAX, since the solar cell can be operated up to its maximum power output to get the maximum efficiency. The efficiency of a typical solar array is normally low at around 10-12%.
Selected PV module max power voltage at STC x 0.85. Maximum power voltage is obtained from the manufacturer’s specifications for the selected photovoltaic module, and this quantity is multiplied by 0.85 to establish a design operating voltage for each module (not the array). Selected PV module guaranteed power output (in watts) at STC.
