Abstract: This study aims to analyse the influence of tilt angle on energy yields and performance ratio of photovoltaic (PV) systems with three PV technologies over the selected cities in Southeast Asia. 10 kWp grid connected PV generator is proposed with net-metering option in Jakarta, Jayapura, Kuala Lumpur, Singapore and Bangkok. Simulation is carried for three different PV technologies positioned at tilt angle (0° to 90° with 15° step variations). It is observed that, PV generators performance in Southeast Asia is in order of Si-amorph, Si-mono and Si-poly. Energy yield is moderate in PV generators at 0° (horizontal) and at zenith, i.e., 90° the output is little. PV generators positioned at 15° tilt angle in Jakarta, Jayapura, Kuala Lumpur and Bangkok shows better energy yields and performance ratio (PR). In similar, PV generator positioned at close to 0° tilt at Kuala Lumpur and Singapore City shows better energy yields and PR.
