Document Summary
Sun supplies energy at the position of the earth at an average rate of 1372w/m^2 at the top of the atmosphere and about 50% of this is delivered to the earth"s surface. For any location on the earth"s surface, this must be adjusted the inclination of the surface to the sun"s direction, then averaged over the day and night hours, and finally averaged over the year. In ontario, the annual averaged solar radiation energy (insolation, r) is r = 3. 5kwh/m^2 per day. If this was delivered continuously over the 24hr day then the intensity would be 146w/m^2 however in reality it is a higher value at noon and zero at night. Insolation is lowest at the winter solstice (dec. 21) and highest at the summer solstice (june 21) Going south from the canada-us border, r increases from 3. 5 to 7 kwh/m^2 per day at the us-mexico border.
