Off-grid energy systems are the main electricity source in rural Bedouin villages in the Negev. Due to the need for electricity, Bedouin households took upon themselves the responsibility of buying and installing photovoltaic (PV) systems. This project is the first of its kind to investigate and collect data on the PV systems installed at the recognized and unrecognized Bedouin villages and to assess their future electricity needs. The project aims to find how heavily Bedouin households rely on the PV systems to provide them with the electricity needed in their daily lives, they use the diesel generators when the PV system are not able to produce energy. Also to find how the generated electricity from PV systems shape the villager’s daily life. Our preliminary research shows that the electricity supply provided by the PV systems is limited and in most households it is not enough for basic appliance usage. Enlarging the current installed photovoltaic system emerged as an urgent need.
