Hi,
It really depends where you're located.
Here in the UK we can get a really "grey" week or more in mid winter where little if any battery charge would be obtained. A 7 Ahr battery can only suppoprt a 100 mA continuous drain for less than three days. Personally, I would not consider a "10 Watt" panel, nor a 7 Ahr battery, to be "compatible" with a 1 watt (100 mA, 10v) continuous load. At the other extreme, in a more "favourable" location and time, the battery could become fully charged in a day, with many hundreds of percent "excess" power.
But (in that other thread) I believe that Werk expected the drain to be significantly less than 100 mA; I can't comment myself as I haven't made any practical measurements.
Cheers, Alan.
