What about storms? I can't even imagine flying a big powerful kite during a storm/
That is very, very unlikely. I have never seen a location (outside of some extreme cases, like high altitude glaciers) where you get >1000 watts per square meter for any length of time.

What you are likely referring to are equivalent sun-hours - the adjusted hours of sun you can get that would add up to 1000 watts per square meter. In my area for example (San Diego) we vary between 5 and 6.5 hours of equivalent direct sun a day. This does NOT mean that you get 6.5 hours of 1000 watts per square meter; it means you get 14 hours of sun that is equivalent to 6.5 hours of "STC" sun (which is how panels are tested; 1000 watts per square meter of radiant energy.)
To be more accurate, we get between 5000 and 6500 watt-hours per square meter per day.
To convert that to electrical energy, you multiply by the panel efficiency and by the area. So if you have two square meters of panels, and they are 18% efficient (which would be very good) then you'd get 1.8 and 2.3kwhr a day out of the panel.
I don't have charts for Canada, but the closest I can get (near Vancouver) gets you between 1400 and 6200 watt-hours per square meter per day. So for you those two meters of panels would get you between 500 and 2200 watt-hours per day.

The data was from Environment Canada and what it stated was "peak sun hours of 6 per day, average, for that area in June".
We measure about 1000 watts/square meter in the area so I equated it to that. I then tacked on an hour on each side of that for the other 12 hours of daylight and a PMMT.
Perhaps the calibration is not set correctly and it is less than 1000 watts.
What max values do you measure per square meter?

Note: It would be less per square yard as it is smaller.
During a normal summer day at best incidence, around 750-800 watts. The only time I have seen close to STC power (i.e. 1000 watts per square meter) is right after a rain.
