Financial analysis of the SHS and the biogas plant indicates that capital investment for these technologies is beneficial. The use of solar PV systems for lighting and power biogas for lighting, cooking and power generation wind and water turbines for power generation have substantially improved the socio-economic conditions of the rural households and communities, enhanced business of small enterprises, improved health services of the rural clinics, improved education of the children, enhanced IT activities in rural areas and finally improved the lifestyle of the rural people. With financial supports from a number of donor agencies, several Govt and non-Govt organizations have gained appreciable expertise and business skills for installation and dissemination of RETs in off-grid remote areas. R&D activities on RETs have started in 70s and gained momentum during the present decade. To accomplish the GoB’s stated goal of providing universal electricity access by 2020, the GoB has encouraged implementing off-grid renewable energy technologies, such as solar home systems, biogas power and micro-wind power systems in coastal areas, and micro-hydro projects in the mountainous regions as a priority. The remote and isolated rural areas are not often feasible for conventional grid-based electrification due to high investment and running costs. Nearly 75% of the population is rural and only about 30% of the rural households have access to grid electricity. About 38% of the Bangladeshi population has access to electricity. various publications and from websites of the relevant agencies. Technical aspects of solar home systems (SHS) and biogas plants were studied at the premises of the user farmers and financial analysis has been done based on collected data. The information presented are taken from both primary and secondary sources. This paper presents the applications and status of the renewable energy technologies in Bangladesh.
DESIGN A DC MICRO GRIDS FOR RESIDENTIAL HOUSE HOW TO
This paper also aimed to mention how to serve the increased demand of a customer with an affordable price by means of DC micro grid system. As a result it cannot meet the increased demand of customers with an affordable price. However, demand of customer increases day by day and old customers as well as new customers is searching a bigger power source than as in SHS. SHS is popular when it replacesany lamp run by kerosene or wax. In Bangladesh Solar Home System (SHS) has reached a great number of installations by the effective programs run by Infrastructure Development Company Limited (IDCOL) which has been started about 12 years ago. It has raised national and international concern and efforts to develop alternative renewable sources of primary energy such as solar, biomass, wind, hydro and other green power technologies are being used to provide sustainable, affordable and comfortable sources of energy. By burning fossil fuels, increasing carbon dioxide (CO2) is rocketed into the atmosphere.
The cost of fuels is high and for this reason the cost of expected generating power is increased tremendously in rustic areas. Majority of the islands and the rustic communities are deprived from electricity and most of them are relying on some fossil fuels for searching their required energy. Generation of electricity is not enough to serve its demand. This paper is mainly addressing the design and analysis of a DC micro grid power system in a remote area in Bangladesh.
