FAQ
Light Emitting Diode (LED) is a device which emits light when an electric current passes through it. A Solar lantern) is a lighting system consisting of a lamp, battery and electronics, all placed in a suitable housing, made of metal, plastic or fiber glass, and a PV module. The battery is charged by electricity generated through the PV module. The lantern is basically a portable lighting device suitable for either indoor or outdoor lighting, covering a full range of 360 degrees. A LED based solar lantern system aims at providing solar electricity for operating LED lights for specified hours of operation per day. 

The broad performance specifications of a white Light Emitting Diode (LED) light source based solar lantern system are given below.
   
  Features
The system should be provided with 2 LED indicators: a green light to indicate charging in progress and a red LED to indicate deep discharge condition of the battery. The green LED should glow only when the battery is actually being charged

There will be a Name Plate on the system body which will give:
Name of the Manufacturer or Distinctive Logo.
Model Number
Serial Number
Year of manufacture
 
 Quality And Warranty
Components and parts used in White LED solar home lighting systems should conform to the latest BIS / international specifications, wherever such specifications are available and applicable. A copy of the test report / certificate stating conformity of BIS / international standards must be submitted to the test centre.
The PV module will be warranted for a minimum period of 15 years from the date of supply and the White LED solar lantern system (excluding the battery) will be warranted for a period of at least 5 years from the date of supply. The battery
should be warranted for a period of atleast two year.
