Abstract

The article discusses the efficiency analysis of the Photovoltaic (PV) modules, namely polycrystalline and amorphous. The performance in question is the instantaneous efficiency obtained from the measurement of the voltage (V) and current (I) data generated by the two PV modules. In addition, it aims to determine the effect of solar radiation on the output power of polycrystalline and amorphous PV modules. The research was conducted in September 2020, with the outdoor location of the Department of Mechanical Engineering, State Polytechnic of Malang (7,944 °S; 112,613 °E). The independent variables in this study are the current and voltage generated, and the type of PV Module (Polycrystalline and Amorphous). The dependent variable in this study is the actual power and instantaneous efficiency. Measurement of solar radiation using the Glentest SM 206 Solar Power Meter. Measurement of Current and Voltage using a Digital V-I Meter. The results showed that the greater the solar radiation, the higher the actual power and efficiency generated by the PV Module. Polycrystalline PV Modules are capable of producing higher average actual power and average instantaneous efficiency, which are 86.83 W and 11.92% when compared to Amorphous PV Modules, which are 43.88 W and 6.01%.

Highlights

The availability of sufficient energy is one of the problems for countries in the world, including Indonesia
The results show that the solar cell temperature is a correlation function of the maximum global solar radiation value, cooling coefficient, optical parameters, physical parameters and geometric parameters of solar cells. [7], [8] Analyzing the efficiency of mono and polycrystalline solar panels for water pump applications in Brazil
The results show that polycrystalline solar panels convert more solar radiation into electrical energy than amorphous solar panels; it is seen that the increase or decrease in the actual power generated by the two types of solar panels is almost proportional to the increase or decrease in the amount of solar radiation received

Summary

Introduction

The availability of sufficient energy is one of the problems for countries in the world, including Indonesia. Because monocrystalline solar cells are made of single crystals of silicon, electrons can flow more through the cells, making PV cells more efficient than other types of solar panels. The multiple silicon crystals in each solar cell make it harder for electrons to flow This crystal structure makes the efficiency level of polycrystalline panels lower than monocrystalline panels. With the development of technology, this type has several advantages over the Silicon Crystalline type This becomes the basis for researching the performance comparison of Poly Crystalline and Amorphous PV Modules, especially in Indonesia. While this research is a series of previous studies by our team, namely examining the performance of several types of solar modules (Mono, Poly and amorphous). While this research is limited to solar radiation variables to compare the performance of the amorphous and polycrystalline types. The output power characteristic of the amorphous type drops drastically to zero (0), which is showed
