      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 scs17 l.jpg
    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
