solar panel how to calculate power

[yassin.kraouch]

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 ???

go for the manufacturers detail otherwise you have to calculate yourself using dummy load circuit test ,read ammeter reading and voltage reading at bright day sun putting perpendicular facing towards sun p=v*i

no this is not the solution, look at this link it give the answer Measuring the Power of A Solar Panel - Solar
