During the time when we builded up the hostel in Masange the villagers asked permanently for support to get light.
A group with 10 members geting a solarlight and every week each member pays a small amount into the group bank as long the light is payed off. Always when in the group bank is enough money another member can join the group and pays also weekly a small amount to the bank in the group. It goes on and on and can be a neverending project as long everybody has got a light.
