Irradiance is the power of solar radiation per unit of area, expressed as W/m2. Irradiation or solar energy is the solar power accumulated over time, expressed as J/m2 or Wh/m2. The higher the irradiance, the more energy is generated. In the PV industry setting, the term irradiation is not conventional. coast guard.teletalk.com.bd WebMay 26, 2005 · Solar Radiation Conversion (mJ/m to W/m) ...
