That "just under" 1 kW over the year average is that in a 24 hour period 

Or is it just the daylight hours whatever they might be?..

He said kilo Watt hour per day, not kilo Watt.

A kilo Watt hour per day is on average (1 kilo Watt * (1 hour / 24 
hours)), so on average 1/24th of a kilo Watt, averaged over 24*365.24... 
continuous hours.

It was something like 340 kWh in 365 days, you'll get more of it in longer days 
of summer and very little of it in winter.

> Or is it just the daylight hours whatever they might be?..

clearly none of it will be outside daylight hours!  but the lower/weaker summer 
sun means even less that just the shorter day length.

e.g. in each of december and january you'd expect 12kWh per month so 0.4 kWh per day

but in may, june and july you'd get 41 kWh per month, so 1.3 kWh per day

Quite, you're never going to get a kW of power out of a 350W panel, but for 
about 7 months of the year, you'll get over a kWh of energy.
