Efficiency Comparison of Different Photovoltaic Modules

Abstract

Solar photovoltaic power generation capacity is rising continuously as a result of various regional, sub-regional renewable energy policies and the impact of technology development, as well as the increasing environmental concerns. Characteristics of photovoltaic modules are provided by manufacturers after they have been tested indoors under standard test conditions. These parameters may vary under exterior conditions. It is thus imperative to establish the quantity of the energy produced by photovoltaic modules under real operation conditions. This study sought to assess the performance of different kinds of photovoltaic module technologies in the city of Gödöllő, Hungary, and ascertain the behaviour of the modules under real outdoor conditions. Modules include amorphous silicon (a-Si), monocrystalline silicon (mc-Si), polycrystalline silicon (pc-Si), transparent monocrystalline silicon module (mc-Si). Measurement of the module characteristics was performed and various meteorological parameters were obtained. Performance parameters such as performance ratio and efficiency are given and analysed. Module temperature was estimated and evaluated in comparison with experimental values. Energy conversion rates of the modules were determined as 9.4%, 4.4%, 10.3%, 8.2% and 10.4% for mc-Si module transparent glass (165 Wp), a-Si module (glass 40Wp), pc-Si module (105 Wp), pc-Si module (60 Wp) and mc-Si (PV-T 180 Wp), respectively. Under the given outdoor conditions, the highest average performance ratio of 85.2% was obtained for the mc-Si module (transparent glass, 165 Wp), exhibiting the best performance, while pc–Si module (60 Wp) showed the least average performance ratio of 71.8%.

The Influence of Selected External Factors on Temperature of Photovoltaic Modules

“…Final mathematical description of polynomial graphical dependencies was obtained after application of fitting procedure and regression analysis. (Kafui et al, 2018) and practice have proved that heat can affect the performance of solar modules and shorten their lifespans.…”

“…All aforementioned conditions have a significant influence on PV cell energy production; however, the most crucial factor is temperature. The effects of the PV module operating temperature on the output efficiency have been described by Jones andUnderwood (2001), Schott (1985), Servant (1985), Kafui et al (2018) and their research results have shown that increasing temperature has a negative impact on the amount of power available. On the basis of the presented facts, the paper Acta Technologica Agriculturae 4 Nitra, Slovaca Universitas Agriculturae Nitriae, 2019, pp.…”

Development and Evaluation of Personal Urban Concept Vehicle Powered by a Hydrogen Fuel Cell

“…This could lead to better on-track results and will provide opportunity for higher ranking in the next Shell Eco Marathon competitions. Additionally, the vehicle can be further improved with the addition of different energy harvesting solutions, like a photovoltaic system with solar panels (Kafui et al, 2019).…”

Experimental investigation to thermal performance of different photo voltaic modules for efficient system design

“…5a and 5b represented, module efficiency value of different PV modules (thin plate Copper indium diselenide, polycrystalline silicon, mono-crystalline silicon, micro crystalline silicone and amorphous silicon) for whole year. It is examined that module efficiency of different types of PV modules are directly linked with maximum power output and inversely related with module temperature [43,[68][69][70].…”
