This report focuses on the design of an LED-based solar simulator, which is widely used in testing Photovoltaic (PV) panels and other products. In recent years, solar power was used in almost every industry, such as Photovoltaic systems installed on the rooftops for residential, small level commercial, public lighting systems and large-scale Photovoltaic power generation. Government launches incentives policies, awareness of environmental issues, plus the lower consumer prices promoted the solar energy uses. However, due to limitations of present technology, efficiency of Photovoltaic systems is unsaturated. Even if there is a small increase in the efficiency, there will be a significant growth for the total energy. Therefore, testing the efficiency and checking the quality of Photovoltaic panel is an extremely important step. The aim of the project is to understand how to make a LED-based solar simulator, with high intensity, can be continuously operated and is expected to meet the International Electrotechnical Commission (IEC) standard: IEC 60904-9. Moreover, the personal motivation for making the LED-based solar simulator is the conviction that solar power is a cleaner, safer and environmental friendly energy. Under laboratory conditions, the solar simulator provides a controllable indoor test facility for testing the PV panels and modules by continuously supporting illumination which is similar to natural sunlight (AM1.5g as defined in ASTM G173-03 standard was used for comparison). The comparison is mainly focused on the range of 360nm to 700nm wavelength. The high intensity LEDs used in this project have wavelengths: 380-390 nm, 400-410 nm, 460-475 nm, 520-535 nm, 584-596 nm, 619-624 nm, 700 nm and IR LEDs. The reason of another IR LEDs used in this project is for expanding the application, it could test other products, not only for PV panels. In addition, the characteristics of the solar simulator is compared with the standard IEC 60904-9.
