This current is called the short-circuit current (Isc), which is the maximum current the solar panel can produce under short-circuit conditions. Check the solar panel specifications, you should see somewhere between 80-105% of the Isc value in full sun at midday in summer. Normally around 8-10A for a 200W solar panel and 4-5A for a 100W solar
Solar panels or photovoltaic (PV) modules have different specifications. There are several terms associated with a solar panel and their ratings such as nominal voltage, the voltage at open circuit (Voc), the voltage at maximum power point (Vmp), open circuit current (Isc), current at maximum power (Imp), etc. All these parameters are crucial
Solar modules are measured at STC, Standard Test Conditions, to benchmark the standard performance specifications: Light irradiance of 1,000 W/m 2. Solar cell temperature of 25°C. Maximum power measurement at STC divided by the surface area of the module tells us the module efficiency.
