Abstract
In Malaysia, we can find pitched and flat rooftop designs the most because of the climate itself. Malaysia experiences a tropical climate. The purpose of this work is to design and explore thermal analysis for various PV installation techniques. Thermal analysis is crucial in order to monitor the PV system performance while observing the power output referring to the output voltage. To measure the output voltage, C++ language programming in Arduino IDE programming language was utilised along with an Arduino UNO R4, micro-controller, and sensors for measuring current, voltage, temperature, light intensity and time. The recorded data was sent through a short message service.This may help the owner get the information of PV performance easily and can identify whether the PV system is required for maintenance or not. Some of the systems were abandoned as a result of the system owners' unhappiness with the systems’ performance discouraging them from updating system faults. The heat analyse revealed that the flat rooftop in configuration 1 encounters higher temperatures than the floating panel in configuration 4, with an average temperature differential of 14.73%. Higher temperatures can exacerbate Potential Induced Degradation (PID). PID is more probable in hot, humid environments, significantly lowering the panel's efficiency. The average power output differential error is around 4.14%, showing that the floating panel (C4) typically provides somewhat more power than the flat panel (C1).
