ABSTRACT
INTRODUCTION
- Background
- Problem Statement
- Objectives
- Brief Methodology
- Structure of the Report
While fossil fuels are used to produce energy, including electricity and heat, a significant portion of the greenhouse gases that cover the Earth and trap solar heat are produced. In winter, the wind is often out of the north and northwest, blowing at a speed of 1 to 3 kilometers per hour (0.6 to 1.9 mph) in northern and central areas and 3 to 6 kilometers per hour (1.9 to 3 .7 mph) near the shoreline. That is far short of the required 2,500 million cu ft (71 million m3) per day, a figure that is increasing at a rate of about 7% per year.
Natural gas supplies more than three-quarters of the country's industrial energy demand.

- Summary
The feasibility of a solar-wind hybrid system for rural electricity in Bangladesh was investigated in a 2012 study by M. Based on technological, economic and environmental factors, this study looked at whether it would be possible to use a solar-wind- hybrid system to electrify rural areas in Bangladesh. Renewable and Sustainable Energy Reviews Evaluation of a Solar-Wind Hybrid System for Rural Electrification in Bangladesh,” by Md.
The performance of a solar wind hybrid system was studied in a rural Bangladeshi hamlet. A small solar-wind hybrid system was installed in a rural village in Bangladesh as part of a pilot project completed in 2018 by the International Center for Renewable Energy and Development (ICRED). In 2019, the Grameen Shakti Group installed a hybrid solar wind system in a Bangladeshi school.
Bangladesh's hybrid solar wind system has the advantage of being able to take advantage of the country's strong solar radiation and high wind speeds. Although the renewable energy industry in Bangladesh is still in the early stages of development, the use of hybrid solar and wind energy systems can significantly help meet the country's energy needs and reduce dependence on fossil fuels. The ability of solar wind hybrid systems to continuously generate electricity both day and night and their potential to reduce dependence on fossil fuels and greenhouse gas emissions are some of its most important features.
Finally, solar wind hybrid power systems can be a cost-effective solution to create energy for homes, providing a constant supply of electricity as well as the potential to reduce dependence on fossil fuels. Despite these challenges, solar-wind hybrid systems have the potential to provide a clean and renewable power source, lower the environmental impact and promote a more sustainable energy future.

- Summary
To maintain the consistency of the system's power generation, these two systems must be supported in relation to each other. Monocrystalline silicon panels: The crystal structure of the entire sample is continuous in monocrystalline silicon panels. Most wind turbines have three blades and are mounted on a tubular tower, which often has the ability to rotate in the direction of the wind.
The aim was to demonstrate how the cost of power fluctuates for different degrees of the allowed capacity deficit. How much users have to pay can be determined by performing a sensitivity analysis of the capacity deficit of the system. Daffodil International University 20 The environmental effects of the solar-wind hybrid system, including any potential effects on land use, wildlife and water resources, will also need to be considered.
The table provides a monthly summary of solar statistics (for tilted PV panels) and the clearness index. Barisal is located in the south-central region of the country, where solar radiation is often greatest, so there should be fairly high levels of solar radiation there. The average temperature in Barisal is presented for all months of the year in Figure 3.11.
Here there is a strong wind current that comes from the Indian Ocean for most of every month of the year. The average temperature in Barisal for all months of the year is shown in Figure 3.14. According to the previous study, the wind speed statistics of Bangladesh are sparsely available outside the coastal region.
Unlike the other months of the year, when the wind speed is sometimes quite low, the wind speed is maximum from June to September.

- Summary
This part of Table 4.2 is shown. According to the table, the system runs out of power at 2.09 kWh per year, while the excess electricity from the other hands is used up at 1,903 kWh per year, resulting in an unmet electrical load of 0.491 kWh. 4.3, both a and b, show that the highest cost of cash flow was the initial capital cost, which the framework estimated at about $6,000. The setup requires initial costs that exceed the operating costs, in this case the replacement of the hybrid system configuration.
To calculate the embedded cost of each component, the net present cost (NPC), which depicts the system's life cycle, is used. The total NPC consolidates all expenses and income arising during the course of the project. The price of the generator mainly consists of the capital cost, which is effectively the running cost.
In order to choose the best mix of solar and wind components, analyzes were made by varying the number of wind turbines and PV modules for off-grid mode. 4.8, both parts a and b, show that the largest cash flow cost was the initial cost of capital, which was expected to be about $6,000 according to the framework. In order to choose the best mix of solar and wind components, analyzes were performed by varying the number of wind turbines and PV modules for off-grid mode.
4.13, both parts a and b, show that the largest cash flow cost was the initial cost of capital, which was expected to be about $6,000 according to the framework. The net present cost (NPC), which represents the life cycle of the system and the total NPC, condenses all the expenses and revenues that arise throughout the course of the project, is shown in Fig. Production data for the same models for three different situations are given in this chapter, along with a comparison of the results.

Environmental and Ethical Issues
Installing a hybrid solar-wind system in Bangladesh could raise a number of ethical and environmental concerns. Land clearing may be required to install solar and wind turbines, which could impact the environment and habitat in the area. For example, large hybrid solar-wind systems could cause traffic, noise and light pollution that would disrupt the daily activities of local people.
There may be ethical issues with purchasing the resources needed to build the solar-wind hybrid system. The responsible supply of all supplies and the maintenance of workers' rights are essential throughout the construction process. It is necessary to carefully investigate and resolve any environmental and ethical concerns that may arise during the construction of a solar-wind hybrid system in Bangladesh, in order to ensure that the benefits outweigh any negative impacts.
Utilization of Existing Standards
Bangladesh National Constructing Code 2010: This code sets out requirements for the planning, building and maintenance of structures in Bangladesh and includes clauses for the incorporation of renewable energy sources such as solar-wind hybrid systems. Many IEC standards, such as IEC 61400 (Wind Turbine Generators) and IEC 61215 (Solar-Wind Hybrid Systems), are relevant to the design, installation and operation of solar-wind hybrid systems (photovoltaic modules).
