DEVELOPMENT OF A SOLAR AID BOX FOR UNDERSERVED COMMUNITES IN THE RURAL AREA In the west bank of PALESTINE Prepared by: Ammar Sha’ar Farah Mahmoud Hiba Dweikat Supervisor: Dr. Tamer Khatib Dr. Mohammed Othman 1 Problem Statement 2 About 1.1 billion people around the world have no access to electricity. In Palestine there are about 600 families live in vulnerable herding remote areas that are not connected to the grid. Lack of electricity services implies laborious work in many domestic tasks to secure basic needs. The existing solutions and alternatives Small, lightweight, decentralized and autonomous generation. 3 SolenX Combination of appliances; LED lamps, Mini Insulin Refrigerator, Mosquito Shocker, Battery Charger and USB ports.
