Hi Wayne;

Well I don't know about Nova Scotia, but the the
rule of thumb is about 1000W/m^2 normal to the Sun.
( Aimed directly at the Sun. ) Plus or minus the
amount of atmosphere the light has to pass through
and and the humidity and dust.

   Got a chance to check out my meter, works great, very sensetive. At
9.30am, got 1020 watts, at noon got 960 watts, so it does not take much
change in conditions to change it, i could not see much difference in
sky conditions. In shade will drop to about 25 w, and will jump up
instanly when sun is on it. Just changing it side ways or up and down 1
deg will change reading. Reflection will put it put it up some, so
reflection of snow should help. I would highly recomend it, works
better than expected. Now i can see why my panels dont always put out
same btus  everyday.  Wayne

 I had my readings wrong, should have been 1020 w at noon. Yesterday at
9.30 was 750w, 10am was 830w, then it clouded over. i need 800 to
10000w for panel to work good. Wayne
