In a new weekly update for pv magazine, Solcast, a DNV company, reports a mixed picture for solar irradiance across North ...

Scientists in China have analyzed the impact of soiling of PV module performance and have found that tilt angle has the ...

As the distance from a point source of radiation increases, the irradiance decreases. The relationship between irradiance, \(I\), and distance, \(d\), can be shown to follow an inverse square law.

Other areas may benefit from enhanced solar irradiance due to stabilising atmospheric conditions on the cyclone’s periphery.

A lamp illuminates a screen of area \(2.0m^{2}\), which is \(4 m\) away. The irradiance at the screen is \(0.02Wm^{-2}\). a) Calculate the power of the incident beam. b) If the screen is moved to ...
