While individual solar cells can be used directly in certain devices, solar power is usually generated using solar modules (also called solar panels or photovoltaic panels), which contain multiple photovoltaic cells. Such a module protects the cells, makes them easier to handle and install, and usually has a single electrical output.
According to the standard IEC61215 10.9.2, when the operating current of the PV module exceeds the photo-generated current of a single cell or cell group in the module, the cell or cell group is in a reverse bias state at this time and consumes power, which causes the hot spot effect (IEC61215, 2005).

A PV module is made up of many cells connected together, and the electrical behavior of PV module is similar to PV cells. Therefore, the PV module parameters are also similar to solar cell parameters.
Solution It is given that at 300 W/m2, maximum output power is 42 watt, and at 700 W/m2 maximum output power is 98 watt. Since the cell temperature is constant, the PV module's maximum power output at any solar radiation condition will linearly depend on the solar radiation power input.
The electric current generated by solar PV is directly proportional to the amount of light falling on it. Suppose, a solar PV module produces 5 A current under 1000 W/m2 input solar radiation, then under 500 W/m2 input solar radiation, the PV module will only produce 2.5 A current (because input radiation is half).
