Reference tables tell us that on June 15th in the Northeastern United States, the Sun's average irradiance is 1,060 watts/m^2. Using the equation below, we can calculate the irradiance absorption of a surface: Sun's Irradiance (w/m^2) x Area of Exposure (m^2) x duration of exposure (hr) = irradiance absorption. What is the irradiance absorption of a 15 m x 10 m roof that experiences 10 hours of direct sunlight on June 15th? Remember: before calculating irradiance, find the area by multiplying length time width
