SOLAR CELL MODULE: System Description

Operating conditions

• The 12V battery is recharged according to the amount of power generation of the solar cell module. Therefore, the 12V battery is not recharged when power generation amount of the solar cell module is low.
  REFERENCE CONDITIONS
  
  

  Item	Environment
  Solar radiation amount	Sufficient amount of solar radiation is required. Example) Weather: Fair, Ambient temperature: 25°C, Period of time: 11:00 - 14:00
  Solar cell module condition	Solar cell module must be in sunlight. The surface of Solar cell module must be free from fallen leaves or dirt.

Recharging 12V battery

• When electromotive force α (unit: V) of the solar cell module exceeds 12V battery voltage in the sun, the 12V battery is recharged at a current responsive to α.
• The 12V battery is not recharged when electromotive force α falls below battery voltage.
