That seems to duplicate what I am seeing in my ERDA Pacific Regional Solar Heating Handbook (Mar 1976 during the other "energy crisis"). It gets worse in winter. I can copy the chart for about 2 dozen western US cities if you like. It gives total solar radiation for each month. It does not talk about Canada but the trend is clear.
We were hearing about that "cheap PV array" that was only a year or two away then too. Still waiting.
I would love to have a solar PV array but I still can't get the numbers to work. I am too poor to have a $30,000 solar energy hobby. At my age, even if these things performed better than they advertise, I would never live long enough to get my money back.
