G'day folks, | nylon fabric and is simi-flexiable. I measured the output at 20 volts open | circuit and 380mA in noon sun. This is over 5 watts and the sun is not as | bright this time of year so it should do even better in the summer when the | sun is higher overhead.
Calculating the wattage of solar panels by using the open circuit voltage and short circuit current does not represent a real world operating condition, albeit a common method used by manufacturers to mug the unwary. >From bitter experience (hill top solar powered microwave telephone network repeaters) I reached the conclusion that once you have got the nominal solar panel/system voltage matched all you are interested in is current into and out of the battery. Batteries operate in a world of current, Ah capacity, watts are virtually meaningless, only giving a rough guide to panel dimensioning for a given load.
