How Radiation and Energy Distribution Work in Solar PV
Irradiance and Solar Energy. Irradiance is the power of solar radiation per unit of area, expressed as W/m 2. Irradiation or solar energy is the solar power accumulated over time, expressed as J/m 2 or Wh/m 2. The higher the irradiance, the more energy is generated. In the PV industry setting, the term irradiation is not conventional.
