Abstract

Due to various initiatives done by the government, solar photovoltaic (PV) installation is now a multi-million industry in Malaysia. In order to produce a system that is relatively maintenance free, it is crucial that the different components involved in the system is the most optimum specification as possible. To quantify the accuracy of the solar PV system especially the solar panel, a reliable performance measurement system is needed. The solar PV measurement system usually comes in terms of irradiance sensor, temperature sensor as well as voltage sensor and current sensor. These sensors are used to correctly assess the performance of the system so that the solar PV output can always be maintained at the desired level. The aforementioned sensors are usually quite expensive and comes separately in the market. Therefore, the objective of this project is to resolve this issue by attempting to combine the several measurement systems into a single system that will be more affordable, efficient, and user friendly. To do so, Proteus 8 software is used to simulate the operation of this Arduino Uno powered solar PV measurement system project in this semester. Three different irradiance and temperature situations are simulated which are set at minimum, average and maximum levels. The simulation results show a promising current and voltage readings which indicate a successful implementation of the measurement system. This project also has successful develop in form of hardware that combining various sensors utilizing Arduino Uno. To ensure this project give a precise and accurate measurement value, it is compared to commercial system and the data analysis show that the measurement value give an error in range of 7 % to 10 % which is quite good for this project. It is hoped that this project will be an outstanding cost-effective solution for solar PV performance measurement system in the future.
