Renewable energy generation is becoming more prevalent on today’s electric grid. The challenges of increasing the percentage of renewable energy will be dealing with the intermittent nature of renewable sources. This book outlines various existing solar technologies. The understanding of each technology and its associated challenges provide a suitable basis to recognize advantages and drawbacks, more importantly it gives the technological development of solar dish concentrator. Three experimental models with various geometrical sizes and diameter of about 0.5m of solar dish concentrators are used to analyze the effect of geometry on a solar irradiation and temperature and in maximizing the solar fraction under Malaysian environment. These models are used to analyze the performance of parabolic concentrating collector’s parameters such as reflector materials, aperture diameter, depth of concentrator, size of focal point and temperature at the focal point with different solar irradiations to increase the thermal efficiency.
