Abstract

Malaysia is a country that has plentiful of solar energy and annual average daily solar irradiation for Malaysia have magnitude of 4.21-5.56 kWh/m², sunshine duration more than 2,200 hours per year. Unfortunately, Malaysia has the main energy source which is oil and gas. In addition to limited stock of negative effects of fossil fuel combustion on the environment have forced many countries to inquire into and change to environmentally friendly alternatives that are renewable energy to sustain the increasing energy demand. There is no greenhouse gases release in this technology, therefore a lot of countries are now focusing more on the technology of renewable energy. Among CSP technologies, system that is suitable for small scale plant and modular which is suitable for small scale area is Parabolic Dish system. This project purpose is to investigate the ability of Parabolic Dish system for weather in Malaysia and make comparison of solar efficiency solar energy in converting electricity due to temperature effect between manual stirling dish system with single axis solar tracker system. This project requires parabolic dish mirror, stirling engine, voltmeter, single axis solar tracker system and thermometer. The stirling engine is a heat engine that converts heat energy into mechanical work to drive a generator then converts mechanical energy into electricity, the stirling engine uses a permanently enclosed volume of gas such as air or helium for mechanical work performance. The dish focuses the sun ray on the cylindrical glass bulb of the stirling engine to heat it up, then the air inside the bulb heats up and pushes a piston which turns an electric generator which produces electricity.
