Irradiance Meter

The Irradiance meter was use to measure the Light source or Sunlight in Watt per meter square.

Due to the fact that the halogen light source is not distributed evenly on the Solar panel. Several readings have been taken on the Solar panel on the individual cells (total 4 x 9 ) = 36 readings.

Average value is set at around at 50 Watt per meter square .
