Potential of Wind and Solar Electricity Generation in Bangladesh

Abstract

Wind and solar energies are the alternative energy sources that can be used to supplement the conventional energy sources particularly in Bangladesh. In this work, the aim is to assess the current wind and solar energy potential in Bangladesh. The wind data for the five stations obtained from Local Government Engineering Department have been assessed, but only two of them seem to be eligible for energy production. Annual average, monthly average, and hourly average wind speeds and wind power densities were calculated from the wind data. The Weibull distribution parameters (c and k), the dominant wind directions, and the frequency distributions were also determined. Experimentally measured solar radiation data are not available over Bangladesh. Measured climatological data such as cloud cover and sunshine duration data of Bangladesh Meteorological Department from 1992 to 2001 used for the estimation of global solar radiation as they are correlated. Technoeconomic feasibility analysis is done for 100 kW grid connected wind and solar photovoltaic (PV) systems. Renewable-energy-based system will bring more environmental benefits than conventional power in terms of human health, reduction of air pollution, and decrease of noise, and so forth. However, in the above estimation, these were not considered.

Performance evaluation of a microcontroller-based solar powered auto-rickshaw

“…Bangladesh is situated in a very suitable geographical position for the solar radiation. Everyday we get bright sunshine 4 to 10 hours and solar radiation in our country is 4 and 6.55KJ/m 2 [5] [6]. In that case solar power is very helpful.…”

Techno-financial analysis and design of on-board intelligent-assisting system for a hybrid solar–DEG-powered boat

“…A research study found that the daily sunlight hours range from 10 to 7 h in Bangladesh, and the authors further reduced this by 54 % (to 4.6 h) to consider the effects of rainfall, cloud, fog, and dust on the solar panels [17][18][19].…”

“…Although the initial installation cost of solar photovoltaic (PV) systems is quite high, the consistent price hike of fossil fuels and increased generation of greenhouse gases have influenced us to conduct a research on performance evaluation and feasibility of solar-powered boats in Bangladesh [19,21,22]. Usually, solar boats include auxiliary source of energy to meet unsatisfied power demand during cloudy and partially cloudy days.…”

Hybrid Decentralised Energy for Remote Communities: Case Studies and the Analysis of the Potential Integration of Rain Energy

“…For instance, approximately half of the Bangladeshi population still lack access to the national grid. Potential employment of solar and wind sources to fill some of this gap are limited by seasonal dependency: solar irradiation peaking between March and May, and wind speeds peaking during June and August [27]. Furthermore, of the average annual rainfall of 1.35 trillion cubic metres that Bangladesh receives, 80% occurs during the Monsoon season between the months of June and October [18,28].…”
