A solar panel has a Vm of 17.2 V and Im of 2.32 A. What is the power of the solar panel?
Answers
Answer:
i think this is not english
Answer:
power = Voltage (V) x Current (I) so a panel Vm is the Voltage at maximum power output and Im would be the current at a maximum output. A 12 volt circuit usually has DC Volts of 17V at the maximum panel output while the battery will show 14 +/- Volts when fully charged. The voltage of the panel is necessarily higher than the battery to charge it. The power output of the panel is somewhat irrelevant since it is dynamic and not constant. What is relevant for the system characteristics, that the ability of the panel to generate more energy than can be stored and sized well enough that panel power will replenish what you use in load from the battery and panel source. This panel has characteristics of a 30 watt output / charging power source.
