Hi, I have a solar power that i would like to calculate its power ( in watt), when i expose it to the solar and calculate the voltage that this solar supply without charge i found 10V, but i would like to know the power in ( watt) in order to compare it with the value given by the manufacturer (16 watt crêt), i connect directly a lamp to the solar power and calculate the voltage (9.3 V) and current ( 0.55A) so the power is about 5 watt, what is the solution to find the right power ???
