   Explanation block diagram

               This project focuses on designing the hybrid solar and thermal for low voltage application. The hardware part, which is for input voltage is solar panel and thermoelectric module The main devices of this project is  thermoelectric cell, solar panel and other related circuit. The photovoltaic panel is use to detect light energy from solar which is main sources, thermoelectric module is use as a device to collect heat produce The two devices are connected in series to provide more output voltage. From the block diagram, there is a 3 differences type of thermoelectric cell will place at difference situation. In Type 1, the thermoelectric will connect to rectifier circuit. So, that the output in thermoelectric will be  hybrid with solar panel output voltage. The ouput voltage from two sources will connect to two supply controller. After that, the result will be send to DAQ by using LABVIEW software. The function of rectifier circuit is to not allowed the current in thermoelectric in reverse direction. This step of work are same goes with type 2 and type 3.

    Material used:

Figure 5: photovoltaic panel

Types of photovoltaic panel that be used in this project is mono-crystaline silicon. Photovoltaic system use solar electric panels to directly convert the sun energy into electricity. Figure 5  above shows the photovoltaic panel that be used in this project.

Figure 6:  Thermoelectric Module TEC-12730T200 

In this project, the types of thermoelectric module that being used is type TEC1-12730T200 which consists of 49 thermocouples arranged electrically in series and thermally in parallel. The bonded metal conductors enable the HZ-14 module to operate continuously at temperatures as high as 250°C (480F) and intermittently as high 400°C (750F) without degrading the module. While the TEC1-12730T200 is well suited for waste heat recovery its reversible properties make it ideal as a thermoelectric cooler, especially for high temperature application where sensitive electronic equipment just be cooled to below the ambient temperatures.
