Description:	A hybrid photovoltaic thermal solar collector (PV/T) is not only capable of generating electricity and thermal energy simultaneously, but could also be use be integrated into the roof. The collector produced is known as the Building Integrated Photovoltaic Thermal (BIPVT) solar collector. The purpose of this research is to design, fabricate and evaluate the performance of BIPVT solar collector through experimental and theoretical analysis. Seven new BIPVT collectors have been built for these particular purposes, including Direct, Oscillatory, Serpentine, Web, Spiral, Parallel-serpentine and Modified Serpentine-parallel flow thermal collector designs. After the design process was completed, the Matlab software was conducted to simulate on the collectors to choose one of the best designs, which based on the energy balance equation. Results obtained from the simulation show that the Spiral flow thermal collector is the best collector. The results show that the collector could give the overall system efficiency of 70.14% with the efficiency of photovoltaic cell around 14.78% at mass flow rate of 0.041 kg /s and solar irradiance of 800 W/m2. Once the simulation results obtained, the actual collectors ware constructed to verify the results of the simulation. Each of the collectors was made of rectangular and circular stainless steel hollow tubes with the size of 12.7 mm x 12.7 mm. The hollow stainless steel was connected using TIG welding include the nipple-part which was then connected to manifold at the front and rear side of this collector. These collectors contain unilateral water channels that only allow water to flow one way in it. It was later affixed to the bottom photovoltaic cell, sized 815 mm x 628 mm x 30 mm using silicone gel and after that covered with thermal insulation material to produce a complete collector, measuring 1m high, 0.65 m wide and thickness of 0.3m. Insulating materials made from polyvinyl resin was used as thermal insulation to prevent the heat from further escape to the air and at the same time produce more uniform temperature throughout the collector. Once the system was completed, it was placed under the solar simulator which able to create average maximum irradiance intensity of 800 W/m2 with an average error at ±5:46%. Irradiance intensity is measured using Eppley pyranometer of 8-48 with ∅ 60 mm casing before it was placed parallel to the level of the collector at the slope of 14°. In this research, the temperature was measured using thermocouple type T. Data were taken every 20 seconds, and the average readings were taken for every 1-minute using a special built data-acquisition system (DAQ). Results in the laboratory show that spiral flow thermal collector gave the highest performance at solar irradiance of 800 W/m2. It produced a combined efficiency of 65% with 13.64% photovoltaic cell efficiency at mass flow rate of 0.041kg/s. After laboratory tests completed, the Spiral flow collector was sent for outdoor testing. All preparations for the outdoor testing were in accordance with the method used in the laboratory. Results from the outdoor testing taken on 16 November 2010, recorded a combined efficiency of PV/T of 65.1% with 11.46 % of photovoltaic efficiency at mass flow rate of 0.041kg/s. Outdoor testing results follow trends as in laboratory test results. Mathematical model was applied to predict the performance of the designed collectors and decisions on theoretical analysis of the results were compatible with the results of an experiment in the laboratory and the field. The designed and constructed of Spiral flow absorber collector recorded much higher overall efficiency comparing to the design of earlier collectors.,Certification of Masters/ Doctorial Thesis" is not available
