We report an innovation that utilizes solar and wind energy in a compact and Apractical way. A mobile solar and wind-powered mobile generator that produces A1.5 kW has been designed and constructed at the University of Bahrain, in Acollaboration with Long International, Bahrain. The renewable-energy system was Aerected on a trailer and is self-contained. It contains 16 solar panels with Aeach panel capable of producing 75 W (Vsc = 17 V and /sc =4.45 A), 2 Rutland Awind-power generators (output 50 Wat a wind speed of 9.8 m s ʹ). 20 deep cycle Abatteries [each of 12 V with 100 Ah (ampere-hours)], a charge controller, and a Avoltage inverter (Power 1500 VA. 6.5 A, frequency 50 Hz). The cost of each watt Ain this mobile station is BD 3.3. i.e. USD 8.6. The system has the advantage of Abeing easy to install (maximum erection time 10 min by two people), produces no noise, looks good. is environmentally friendly, reliable and educational.
