What I *actually* want to know is the 'average over the year' *watts*
from a panel.Â* I could work it out backwards from the above


well it's not difficult e.g assume you live in cambridge, a 1kW panel
would give you 863kWh/year, so a 250W panel a quarter of that is
215kWh/year or 0.6kWh/day, an average 25W


Average insolation is indeed about 10% of peak.

I get emails enthusing about how Gridwatch shows how great solar power
is. And why is coal still on the BIG dial

They are never posted at midnight Or in te winter.
