It must be my panel then
It is a 40 watt on (iirc) and was from a reputable UK manufacturer (or so the advert said

)
I am using it right now at the "Valentines meet" at Shirebrook. When the sun is clear, though low in the sky it is right now producing ~2 amps, but as soon as a cloud moves over the sun it drops to less than 1 amp. I know from experience that on a "normal" cloudy day it is often down to 1/10 of an amp.
Funnily enough, the other 80-90 folks here have been talking about this just an hour ago whilst watching the amps go up and down with the clouds.
So if every one elses work well on a dull day, it must be just the make of mine is not as good
So, what makes of panel do you folks have that you find provide useful amps even on a dull day (and what Wattage are they and can anyone quote currents for, say a sunny summers day compared to a dull spring day) ?)
Yours, jealously,
John
