the hows whys of solar lights
The hows & whys of solar lights

Solar light brighter, healthier&cheaper than kerosene lamps

  • Brighter than kerosene lights
    • 15-20 times better quality light
      • 150-200 lumens vs. 10-20 lumens (kerosene ‘dibri’)
  • No smoke
    • Virtual elimination of soot-related health hazard
  • Cheaper than kerosene lights
  • No moving parts, very little maintenance
  • Near-zero heat
    • Can sit very close to lamp: boon to villagers & shopkeepers
  • Above all, endless source of energy
solar lighting options for the poor middle class
Solar lighting options for the poor & middle class

3 options

1. Central charging station with lanterns on rental for low-income villagers

  • Regular income for the rural entrepreneur
  • Micro-financing by MFI/RRB/CB for purchase of lanterns by the poor

2. Solar lights with small panels for relatively well-off villagers

  • Direct purchase & use

3. Village adoption

  • Options 1 & 2 practical for both urban & semi-urban customers
    • Low-income areas
    • Shops/mandis (marketplace)
    • Emergency lights

Solar Charging Station (SCS)

The Concept

  • Solar charging stations
    • At RO/KSK/LPGD or Any central location
  • Direct charging during the day
    • Batteries inside the lanterns

Solar Charging Station (SCS)

The Concept

  • Customers pay rent for lantern & a fee for charging lantern on a daily/monthly basis
    • Every evening, Customers bring the discharged lantern and take a charged lantern with them
    • Alternatively, the charging station owner arranges for delivery & collection of lanterns
