Mostly diesel generators supply the electricity to the off-grid regions. Use of diesel leads to increased greenhouse gas (GHG) emissions which is a big environmental concern all over the world. Solar Home Systems (SHSs) offer promising solution to the areas that are not connected to the grid. More than 3.6 million SHSs are installed in remote locations across the country. Most SHSs in Bangladesh use small tube lights as the lighting source. However, the recent SHSs make use of LED bulbs instead of the tube lights in order to decrease the PV panel size which would lower the initial capital cost and annualized cost. In this study, two different Solar Home Systems were analysed having tube lights and LED bulbs as the lighting source, respectively. Each of the SHSs consists of 6 lights (Tube light/LED bulb) and 2 fans with operating hours of 4 daily. The analysis shows that the SHS with tube lights requires initial capital cost of $432, which is 48% higher than the system having LED bulbs as the lighting source. As the SHSs do not use any fossil fuel, there is no operational GHG emission. However, a large amount of energy is used to manufacture PV panels, which needs to be quantified to understand the environmental impact. Energy consumption to manufacture the solar panels of Solar Home System with LED bulbs is 1.44 MWht which is 25% lower than the SHS with tube lights.","PeriodicalId":365312,"journal":{"name":"2016 4th International Conference on the Development in the in Renewable Energy Technology (ICDRET)","volume":"321 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-02-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132386618","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, a biogas based chain business model is designed for a community of 500 families, where people sell various wastes (organic waste, cow dung and chicken manure) to biogas plant authority, in contrast buy electricity, cooking gas and bio-fertilizer at affordable price. The model is abstracted based on developing countries like Bangladesh and analyzed for rural community, although it is also applicable for developed countries. Proper electrification is still not satisfactory and natural gas for home application facilities are totally absent in rural areas of Bangladesh. Use of chemical fertilizers in agriculture causes serious environmental and health hazards. However, this model eventually ensures financial gain, electrification, biogas for homestead use, agricultural growth, proper waste management and therefore, sustainable development of rural community in the long run as well as economic benefit of the entrepreneurs.","PeriodicalId":365312,"journal":{"name":"2016 4th International Conference on the Development in the in Renewable Energy Technology (ICDRET)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-02-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124734001","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The views of a range of institutional stakeholders related to SHS were explored by problem centered interviews and by participatory observation. An improved model of success is developed which is capable of providing a quantitative measure of success for SHS implementations. Five groups of key stakeholders have been determined. The most important self-set goals for the institutional stakeholders are profit, quality and social benefit. The most important success factors that encourage the achievement of self-set goals were retrieved and are discussed. Measuring the level of achievement of the defined self-set goals is the largest challenge in this process. The refined model of success demonstrates the complexity of measuring the success of Solar Home System implementations.

In this research work, AMPS (Analysis of Microelectronic and Photonic Structures) simulator was used to examine the performance parameters (Jsc, Voc, FF and conversion efficiency) of ultra-thin MoTe2 PV cell through numerical analysis. During the study, it was found that absorber layer thickness of MoTe2 PV cell is adequate to achieve cell efficiency at satisfactory level. In addition, the hidden potentiality of MoTe2 PV cell was examined by inserting Indium Telluride (ImTe3) back surface field (BSF) between absorber layer and back contact metal. The conversion efficiency of 17.06% (FF = 0.730, Voc = 0.98 V and Jsc = 23.74 mA/cm2) has been achieved for 1 μm absorber layer of MoTe2 PV cell without BSF, whereas higher conversion efficiency is 25.29% (FF = 0.847, Voc = 1.08 V and Jsc = 27.60 mA/cm2) achieved at room temperature with only 0.7 μm of MoTe2 absorber layer along with 100 nm In2Te3 BSF. This research work compares the thermal stability of the structure of MoTe2 PV cell with and without BSF. It was found that the normalized efficiency decreased in response of increasing the operating temperature at the gradient of -0.0275%/°C without BSF. For the addition of In2Te3 BSF in the proposed MoTe2 PV cell, the degradation of normalized efficiency was too less in the range of higher operating temperature.","PeriodicalId":365312,"journal":{"name":"2016 4th International Conference on the Development in the in Renewable Energy Technology (ICDRET)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-02-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122678519","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Consequently, the only option that is left open to developing countries is renewable energy. Among renewable energy solar, wind, hydro, geo-thermal and wave energies are most reliable, which do not cause carbon emission. Solar energy can be used in many purposes like water heating, air heating etc. Among the various types of solar collector, evacuated tube solar collector is one of the most effective water heating device. An evacuated tube solar water heater was constructed from locally available materials and investigated in the department of Mechanical Engineering of KUET. In the first attempt, the highest. storage tank temperature obtained was only 47°C. In the present attempt, cylindrical parabolic reflectors were placed under each evacuated tube.
