Temperature Control And Investigation Of Parabolic Dish Based Concentrating Solar Power (CSP) In Malaysia Environment

In the Renewable Energy Act 2011, the focus is on solar energy particularly the solar Photovoltaic, whereby the solar thermal, such as the Parabolic Dish Concentrating Solar Power (CSP) is not given enough attention. This could be due to the lack of a thorough investigation of implementing solar CSP...
