Abstract
This research aims to study the use of wind and solar energy to generate electricity from solar chimneys system installed on roof-deck of high-rise buildings. The principle of operation is that the energy from the temperature difference within the solar chimney system generates the movement of hot air inside the chimney to drive the propellers and DC generators to generate electricity. The system comprises of three main components: heat storage unit inside the chimney wind turbine and DC generator unit. The research operation was divided into 2 trials. The first was a comparative study of temperatures at different positions within the chimney by experimenting with two types of heat-accumulation surface materials, black steel plates and asphalt. And the second trial was a comparison of the amount of electricity generated. Results from the trial showed that different measurement positions had a significant effect on the temperature that occurs within the system. The position of P2, which is the position at the base of the chimney, is where the average temperature is highest. By surface material, black steel plate can collect heat and provide higher electrical energy than asphalt surface material. The maximum temperature inside the chimney is 64 degrees Celsius and the maximum voltage is 12.63 volts, 40 milliamperes.
