Solar Poweras Renewable Energyfor Home Systemsin Bangladesh 2

The energy requirements of the world are increasing at an alarming rate and the demand of power has been running ahead of supply. It is now widely recognized that the fossil fuels (i.e., coal, petroleum and natural gas) and other conventional resources, presently being used for generation of electrical energy, may not be either sufficient or suitable to keep pace with ever increasing demand of the electricity of the world. Generation of electrical power by coal based steam power plant or nuclear power plants also causes pollution. This is likely to be more acute in future due to large generating capacity and greater awareness of the people in this respect. Recent severe energy crisis has forced the world to develop new and alternative methods of power generation, which could not be adopted so far due to various reasons. The magneto-hydro-dynamic (MHD) power generation is one of the examples of a new unique method of power generation. The other non-conventional methods of power generation may be such as solar cells, fuel cells, thermo-electric generator, thermionic converter, solar power generation, wind power generation, geo-thermal energy generation, tidal power generation etc. This paper elucidates about solar energy system and the future of using a solar energy system in every house in Bangladesh. It also included the study of socio-economical factors related to widely use of solar energy in Bangladesh.

Energy is not the ultimate demand of world but cost-effective and eco-friendly energy is the demand of world. But it is tough task to look for safe and cost effective power source. Today’s world has marked solar energy as one of the prime source of energy which can help to fulfill the demand of energy as per demand if it can be used properly. Solar energy is used either in direct or indirect form as sun is the source of all kind of energy. Bangladesh being in the subtropical region solar energy is more suitable source than other power sources. In Bangladesh solar energy is not used in large scale but gradually use of solar energy is increasing. Reports says that Bangladesh's installed electric generation capacity was 10289 MW in January, 2014 out of which only 15 MW is generated by solar energy and used in rural households which is less than .01% of the total electricity generation. But Bangladesh receives an average daily solar radiation of 4-6.5 kWh/m2. Now comes the point how and where this solar energy can be used. Solar power can be used in irrigation system, LED Street lighting across 5000 kms streets, even in human driven rickshaws. Thus solar energy can be the best alternative of other power sources. Considering all facts of power production available new technologies and application of solar power with storage facility, probable capacity, cost per unit power, efficiency, suitability for Bangladesh discussed here in this paper so that solar energy can be considered as one major source of electricity of Bangladesh by applying new technology for the best use of solar energy in Bangladesh to eliminate energy crisis.

Present Status of Installed Solar Energy for Generation of Electricity in Bangladesh, 2013

Electricity is a basic need of our daily life. Our daily life depends on the amount of electricity usage. But in our country only 40 percent people has the access of the electricity. Moreover fossil fuel is non-renewable, so it is diminishing day-by-day. As a result we need different solution of electricity generation. In our country, so renewable energy is becoming more popular day by day along with the world. Solar Energy is one of that kind renewable energy. Its application is increasing day by day. Bangladesh has good availability of solar energy to generate electricity. In this study production of electricity using solar energy in Bangladesh along with the world has been shown in details.

Background: Bangladesh is one of the densely populated countries in the world. The total population is about one hundred sixty five million and most of the people are living in village or rural areas. A large number of families have no electricity connection for different causes in rural areas. The target of the government of Bangladesh is confirming under the electric coverage for all the people by 2021. Method: Providing this access to electricity, the grid lines are presently overloaded and load shedding is a very common practice for the people of Bangladesh, especially for rural area. Rural electrification plans should be individual generation systems. Result: One of the best solutions is solar home systems (SHS). This system is well-known, very effective and a vast number of rural families are using this SHS program in Bangladesh. For huge load shedding, people who are already under electric coverage also feel and understand the necessity of SHS. The main difficulty of the SHS program is high primary installation cost on the basis of the ability of users; generally, they are very poor and with low-income people. In this paper, we explain that the SHS programs become economically affordable for rural people of Bangladesh by using the castoff battery from electric transport which is available and popular in rural area. Conclusion: Also, I have shown the total cost for a complete SHS became only 5635 Taka (1 USD = 82 Taka) or 69 USD and the yearly cost of an economy family in rural area is only 3.4 USD.

Confronting Climate Change in Bangladesh, 2019

Access to electricity is an important part of the Sustainable Energy for All (SE4ALL) initiative under the United Nations. Globally about 1.2 billion of people are deprived of electricity, mostly concentrated in rural areas of developing countries including Bangladesh. About two-thirds of the rural population in Bangladesh are yet to enjoy this basic utility. Grid-based electricity is challenging for various reasons including technical, and commercial issues. Development partners including the World Bank started a formal approach for promoting renewable energy and more than 3 million solar home systems have been installed in the off-grid areas of Bangladesh. By replacing kerosene, solar energy has not only facilitated people with an option of a much greater quantity of far-higher quality of lighting, at a lower cost, it has reduced the safety and health risks associated with kerosene, particularly among women and young children. However, considering that only about 10% of people in off-grid areas have adopted solar systems to date, the remaining potential for carbon emission reduction and adaptation is large. In Bangladesh, solar systems are a proven renewable energy technology in dealing with climate change and enhancing socioeconomic development. However, there are some remaining technical, commercial and attitudinal constraints which need to be addressed to ensure sustainable development.

Power is one of the most important factors in developing the economy and the standard of living of a country. Like the rest of the countries of the world, in Bangladesh the demand for power is increasing day by day. To fulfill our future power demands, Solar Home System (SHS) seems to be the only feasible form of renewable energy despite the cloudy climate in Bangladesh. The objective of the study was to observe the present conditions of the SHS, the degree of satisfaction experienced by the users of SHS, finding the prospects and constraints as well as contributing in the field of solar energy through presenting and highlighting important principles of solar energy. Our study revealed the users’ satisfaction level to be not that encouraging due to low back-up time, high cost and increased interest rate. If these hindrances are overcome then this would show positive proliferation in the energy sector of Bangladesh.

— Solar energy is one of the most popular form of renewable energy. The use of solar panel is increasing rapidly all over the world. Fortunately, the location of Bangladesh is quite suitable for harnessing solar energy. However, large area is still uncovered either by grid electricity or by electricity generated from renewable sources. In the off grid areas of Bangladesh, solar home system (SHS) is getting popular day by day due to its declining price and due to favourable financial packages offered through Infrastructure Development Company Ltd. (ID-COL).Around 50,000 SHS are being installed every month under IDCOL program only.[1]. Already IDCOL has achieved a target of installing two million SHS by March 2013. With the gradual increase of per capita income and GDP growth, people are more inclined to lead a better life by having electricity in their homes at a higher price than that of grid electricity. However, there are some challenges that need to be mitigated to make the SHS viable and cost effective in future. In this paper, a study has been made to assess the challenges faced by the SHS users in a remote village in the district of Madaripur, Bangladesh. The objective of the study was to observe the present condition of the SHS and the degree of satisfaction enjoyed by the customers of SHS. It has been found that the satisfaction level of the people is not that encouraging due to low back up time (highest for three hours) in the evening and also high cost involved in the replacement of batteries. The paper focuses the problems faced by the SHS users and suggests some alternative solutions to provide electricity to the users for a longer period of time throughout day & night. The socio economic benefit that can be derived by providing electricity for a longer period of time is immense. The major constraint of SHS has been highlighted first and then min grid/ micro-grid type generation system has been proposed to provide un-interruptible electricity at a lesser cost.

Solar Home System based rural electrification has seen dramatic progress since the start of the Rural Electrification and Renewable Energy Development Project (RREDP), which is financed by Infrastructure Development Company Limited (IDCOL) since 2003. Recently a technical audit was done for the Solar Home Systems. This paper illustrates the findings of the technical audit during the field visits to four different areas of Bangladesh. The study has revealed some technical shortcomings of the SHS packages sold in Bangladesh. These include incompatible component combinations, faulty installation, lack of quality control of component parts and lack of adequate quality standards and quality enforcement. The paper also proposes some simple solutions to address these issues so that the SHS industry will enjoy continued success in Bangladesh.
