Abstract

Life cycle assessment (LCA) is an extremely useful tool to assess the environmental impacts of a solar photovoltaic system throughout its entire life. This tool can help in making sustainable decisions. A solar PV system does not have any operational emissions as it is free from fossil fuel use during its operation. However, considerable amount of energy is used to manufacture and transport the components (e.g. PV panels, batteries, charge regulator, inverter, supporting structure, etc.) of the PV system. This study aims to perform a comprehensive and independent life cycle assessment of a 3.6 kWp solar photovoltaic system in Bangladesh. The primary energy consumption, resulting greenhouse gas (GHG) emissions (CH4, N2O, and CO2), and energy payback time (EPBT) were evaluated over the entire life cycle of the photovoltaic system. The batteries and the PV modules are the most GHG intensive components of the system. About 31.90% of the total energy is consumed to manufacture the poly-crystalline PV modules. The total life cycle energy use and resulting GHG emissions were found to be 76.27 MWhth and 0.17 kg-CO2eq/kWh, respectively. This study suggests that 5.34 years will be required to generate the equivalent amount of energy which is consumed over the entire life of the PV system considered. A sensitivity analysis was also carried out to see the impact of various input parameters on the life cycle result. The other popular electricity generation systems such as gas generator, diesel generator, wind, and Bangladeshi grid were compared with the PV system. The result shows that electricity generation by solar PV system is much more environmentally friendly than the fossil fuel-based electricity generation. ©2019. CBIORE-IJRED. All rights reserved

Abstract

Global GHG (greenhouse gas) emissions are increasing substantially and electricity sector is one of the key contributors to the world’s total GHG emissions. GHG emissions cause ozone layer depletion and global warming. Different policy regulation agencies are adopting regulations to reduce GHG emissions in various sectors. People already have started power generation from cleaner sources. Renewable energy sources can provide cleaner electricity. Bangladesh is a densely populated country and most of the country’s electricity is produced from natural gas and coal. The Bangladesh government has set a goal to utilize renewable energy for the production of 10% of its electricity by the year 2020. Bangladesh has a lot of isolated coastal areas which are not connected to the national grid which can be electrified by using abundant wind energy. In this study a techno-economic analysis has been conducted for an off-grid island of Bangladesh. The analysis was conducted by developing a data intensive model that calculates the generation cost of electricity from wind energy. The model also estimates the capital cost of the system. The model shows that electricity can be produced from wind energy at a cost of $0.57/kWh. The system’s capital cost was calculated to be $63,550.16.Article History: Received October 15th 2016; Received in revised form January 26th 2017; Accepted February 4th 2017; Available onlineHow to Cite This Article: Rahman, M.M., Baky, M.A.H, and Islam, A.K.M.S.
