Hi,
I am sorry to differ, but be assured that the rated output on a panel is possible and is indeed easily exceeded.
I have a 40W panel rated at a maximum of 2.23A which can regularly output over 2.5A.
Panels are rated at a solar insolence of 1,000W per sq m. In Australia on very clear days solar insolence can easily exceed this figure and if this happens in the morning or in windy conditions which will keep the panel cool, current figures will exceed the panel specifications.
So, please change the word impossible to something which is actually accurate.
Failure to achieve the rated output is regularly caused by recovering batteries that are fully charged, panels not optimally aligned to the sun, or panels supplied by a dodgy supplier.
If I was buying panels, on delivery, I would set them up optimally in good sunshine ensuring they were not hot and measure the S/C current. If it did not provide the rated Isc, they would be returned as faulty.
take care
Mike
