What are the KW hrs per sq meter for Seattle in summer? I can't find the area chart for there and don't know the zip code. I ASSume it would be similar to Victoria's.
I did get the sunlight figures off the other site for Seattle of 4.83 high, 1.6 low, 3.57 average.
If I understand Mr Wiz's calculations you could predict the actual amps and so amp hrs expected for given sized panel compared with its "name" wattage and amps specification. I am suspecting in Seattle/Here you would need twice the panel wattage to get the specified amps it says on the label.
Thanks
