A model has been presented to estimate the battery size in a Solar Home System with respect to the night time load and the panel size. Falling solar panel cost has opened up the possible options to reduce the battery size by increasing panel size. It has been shown that although the cost of the system increases by a small margin, an increased size of the solar panel enhances the overall energy output...
Solar Home System (SHS) based rural electrification has experienced a considerable growth in Bangladesh since the start of the Rural Electrification and Renewable Energy Development Project (REREDP) in 2003. The initial target of 50,000 SHS installations in off-grid areas was achieved within 2.5 years, 3 years ahead of schedule. After achieving a revised target of 200,000 SHSs, ahead of schedule in...
The adverse effects of Green House Gases (GHG) inspired the industrialized nations (Annex 1 countries) to think about the mitigation of GHGs. After the widespread acceptance of the Kyoto Protocol organized by the United Nation Framework Convention on Climate Change (UNFCCC), the developed countries can meet the obligation by reducing domestic emissions or by using one of the three Kyoto mechanism...
Bangladesh is experiencing a great success in Solar Home System rural electrification. Recently a study of a technical audit of SHS project shows non-uniformity in Solar Home System (SHS) packages in Bangladesh. A detail analysis of factors influencing the reliable design of SHS packages has been analyzed and finally optimized SHS package has been proposed for available PV system components considering...
The commercial success of solar home systems in Bangladesh depends on the extent to which it can fulfill the needs of the end users, which will motivate users to invest money in SHS systems. This paper has explored the factors that can make SHS commercially viable in Bangladesh, and how far the SHS industry in the country has come to being commercially viable. The customers in Bangladesh have found...
The waste materials that are produced daily from different sources can be used to produce energy from which we can get electricity. The conventional fuels required for production of electricity is decreasing day by day and it is very important to find out alternative sources which can be used as the fuel for the production of electricity especially for developing countries like Bangladesh. This paper...
Bangladesh is experiencing a rapid increase in teledensity after the advent of mobile telephony at the end of the last millennium. At the same time the power crisis is rising. The success of rising teledensity depends on the availability of reliable power. There are many telecom service providers in Bangladesh and it is predictable that in the near future the number of operators will increase. So...
The efficiency of even the state of the art existing solar panels is low compared to other energy conversion methods. Solar panels are expensive, and consequently it is important to maximize the energy harnessed through the panels used in solar home systems and other applications. One source of inefficiency - incorrect orientation or positioning of the panels; can be removed by adjusting the positioning...
The sustainability of the SHS project dependents on the technical performance of the system. The technical performance of the SHS depends on the technical quality of the component parts of the SHS. Commonly used Solar Home System equipments were tested in the lab during a technical audit of SHS of IDCOL'S (Infrastructure Development Company Limited) Rural Electrification and Renewable Energy Development...
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...
There are consumers in Germany who have an energy demand of several kWh/d, but who do not have grid connection. Energy supply from renewables is an ecologically friendly as well as an economically viable option for these consumers. The paper describes the energy solution for an alpine hut, Brunnstein Hutte, located in the mountains of Mittenwald in southern Germany. It describes how the energy demand...
The looming energy crisis, heightened by the continuing depletion of fossil fuels, accentuates the need for deployment of renewable energy resources in Bangladesh, now more than ever before. Though hydrocarbon resources in the country are limited, the substantial availability of renewable energy sources in the form of solar, biomass, hydropower and wind energy offers opportunities of sustainable energy...
