The benefits of photovoltaic hybrid systems are (a) improved reliability and energy services, (b) reduced emissions and pollution, (c) provide continuos power supply, (d) increased operational life, and (e) reduced cost, and more efficient use of power. A photovoltaic diesel hybrid has been installed and operated successfully at the middle and top stations of the Langkawi Cable Car resort facilities. The operational concept of the hybrid system is that solar will be the first choice of supplying load and excess energy produced will be stored in battery. Diesel generator set will be a secondary source of energy. A microprocessor-based controller to manage the energy supplied and load demand controls the system. The hybrid system consists of diesel generators with electronic control system, lead-acid battery system, solar PV, inverter module and system controller with remote monitoring capability. This paper presents the performance of the hybrid systems.
