But the building can installing the solar panel location and space are limited，in this circumstance, the only way is improving the efficiency of generation electricity. So that the solar panels are not just a single solar panel power generation to integrate other components or devices to achieve higher power generation by using a multi-directional integrated approach. A novel all-in-one the micro-energy harvesting hybrid generation system (All-in-one μHGS) is developing for buildings and autonomous Wireless Sensor Nodes in building network. This All-in-one μHGS system consists of 3 sub-systems: (a) the two-stage parabolic trough concentrating beam splitting PV/T (TTCSPV/T) system (b) solar cell with integrated TEG coupling phase change materials PCM(high temperature) (SC/PCM/TEG) (c) thermoelectric generator with phase change materials PCM(low temperature) (TEG/PCM), However, some challenges about the development of the hybrid generation system. Such as, the energy of irradiation is not fully used due to the large heat loss through air convection; the temperature difference across TEG model is still relatively low. Thus, in here, a novel micro-energy harvesting hybrid generation system is developed through an integrated design to achieve higher power generation. The main steps of this study are divided into two categories；simulation and experiments, respectively. The experimental part is based on the climate data of Hsinchu City in Taiwan as the environmental parameters，The solar panel with and without integration the collector will be placed in natural daylight to record the voltage and current and compare whether the difference between the two. And then, measuring current and voltage of the solar panel integration with collector、phase change materials、thermo-electrics and heat sink (All-in-one μHGS) to achieve higher power generation. In final, by using thermal imager records its temperature distribution, and validates the results of numerical (ANSYS/Fluent) and experiments, and to prove the energy storage effect of phase change materials works or not. Results of this work show the novel micro-energy harvesting hybrid generation system is developed through an integrated design to achieve higher power generation.
