WebApr 13, 2024 · Assuming direct normal solar irradiance is I, then $\ I * cos( \theta$) gives the irradiance on a tilted surface in W/m2.Integrating this over a period of time: (J/m2) and the same integral over dω (angle) is in Wh/m2.. Edit: Although the unit is in Wh/m2 (Watt Hour per sq meter) but the integration is on dω(angles). This is where I am getting confused. WebInsolation refers to the amount of energy (in Joules or more commonly kilowatt hours) per unit area for a given time. For solar array sizing the most useful units are in kWh per m² per day.. Irradiance is another term thrown around. Solar irradiance is the amount of power (in Joules per second or Watts) arriving at any moment.
