Estimation of sky illuminance for solar energy technology applications in Malaysia / Harizal Omar

The aim of this project is to produce sky illuminance and sky irradiance for Malaysian sky. Therefore, the sky luminance and sky radiance should be measured first in order to get the instantaneous incident of solar energy which is illuminance and irradiance. Furthermore, illuminance is one of the mo...

Therefore, the sky luminance and sky radiance should be measured first in order to get the instantaneous incident of solar energy which is illuminance and irradiance. Furthermore, illuminance is one of the most important elements in daylight. Therefore, sky scanner is selected to be the equipment that will produce the luminance and radiance data. But, the radiance is also needed in order to determine the ratio of the luminance to radiance which is global luminous efficacy. Then, the value of this ratio will be used to convert the solar radiation to be a global illuminance. The sky scanner is designed to measure luminance and radiance of 145 points of sky dome shaped. The daily measurements had been done from 6.30 am to 6.30 pm every day for one month. The sky scanner required a personal computer in order to install the data from the measurement that had been done. In Malaysia, solar energy studies and applications are considered new. The applications of solar energy in Malaysia can be classified into two categories which are thermal systems and photovoltaic systems. Thermal systems mean the conversion of solar energy into thermal energy and photovoltaic systems mean the conversion of solar energy into electrical energy (Sopian, Yusof, Baharudin, 2000). The latest addition to these categories is the use of natural lighting from solar energy (Zain- Ahmed, 2005). Solar energy is expected to play a very significant role in the future especially in developing countries, but it has also potential prospects for developed countries. Hopefully, the results of the ratio between illuminance and irradiance or luminance and radiance which is around 98.20 lm/ W is very useful in order to develop our country to be more efficient in sustainable development. 2005 Thesis https://ir.uitm.edu.my/id/eprint/75060/ https://ir.uitm.edu.my/id/eprint/75060/1/75060.pdf text en public degree Universiti Teknologi MARA (UiTM) Faculty of Mechanical Engineering Zain Ahmed, Azni
