Renewable energy is of great importance for today’s world which is generally produced from natural sources. Countries like Bangladesh has to use this energy to meet their energy demand. Day by day the demand of electricity is increasing in stormy pace but our resource is limited. So using renewable resources i.e. solar power to meet the demand of electricity is highly necessary especially rural and remote areas. This paper examined the nature and extent of solar energy in Boyarjapha village of Paikgachha Upazila of Khulna district to analyse the effects of solar panel in their daily life. Many positive impacts of solar power were found out such as better quality lighting, education, entertainment, communications, business, increasing working hours, women empowerment, increasing awareness etc. There are a few bad effects of solar energy too. But Government intervention is a must to ensure better quality results in coming future. Similarly, government has to take serious steps to advertise solar electricity in remote areas of Bangladesh

Energy use always increases, especially fossil energy. Through the National Energy Policy, the government continues to strive to increase the role of new and renewable energy sources so as to reduce dependence on fossil energy. Solar power generation is a type of renewable energy generator that capable to convert solar energy to electric energy. The main components of solar power generatios are batteries, solar panels, charger controllers, and inverters.  Solar power generations technology itself is always being developed, such as automatic monitoring and sun tracking systems designed to improve system performance. One of the applications of solar power generations is in the household sector. In this sector consumes 49% of the national electricity energy in 2018. This type of generator is categorized as a roof solar power generations. Based on existing data, there were 1400  roof solar power generations users in September 2019. The development of solar energy utilization for the household sector is very appropriate because it can help achieve renewable energy about 23% in 2025 and 31% in 2050 in the national energy mix.

INTRODUCTION On the basis of dynamic building simulations within a maximal realistic framework, it may be useful with respect to the overall energy balance to dispense with pursuing a minimal surface/volume ratio of buildings—thus minimizing heat losses across the building shell—in favor of solar energy use. The specific use of the building (here: office or residential) plays a crucial role. Balancing the energy demand for heating and cooling and a possible photovoltaic yield, a surplus is possible in all cases under investigation. Long, low unobstructed buildings perform best due to large portions of roof area suitable for solar energy use. For tall buildings with less roof area, parts of the facades may be used for solar applications which makes them also perform better than compact designs. If the total energy demand including auxiliary energy for HVAC and especially electricity for the office and residential usages, respectively, is considered, compact cubatures of the size considered here (about 3500 m2) are not capable of providing positive energy balances. Residential usage performs worse than office use. Investigations are performed for the climatic conditions of Berlin, Germany.

Solar power is the burgeoning method of continual energy. The assignment is designed and carried out the use of dual axis sun tracker system. In order to maximise power era from solar, it’s important to introduce sun ray monitoring systems into solar electricity production. A dual-axis tracker can boom power through monitoring solar rays from switching photovoltaic cells in various directions. These photovoltaic cells can rotate in all directions. The LDR (Light Dependent Resistor) have been used to feel the depth of mild at 30 degree every or at 180 degree general and ship the information to microcontroller. This assignment also can be used to experience rain drop, temperature and humidity using sensor and they may be displayed on LCD. We can save the Solar energy in battery.

Purpose – The purpose of this paper is to examine and discuss, in-depth, how solar electricity can be developed and used to tackle grid electricity-related problems in African countries suffering from unreliable and inadequate grid electricity. Design/methodology/approach – The paper discusses in depth the current status of grid electricity in Africa continent and suggested solar electricity as an alternative cost-effective method to the existing grid electricity problem in remote areas. An extensive analysis of the major contribution of solar electricity in various sectors such as economic, health, communication, social and environmental benefits is provided. The paper concludes with a discussion on how solar power generation can be developed. Findings – The paper shows that in developed countries where ICT has been applied extensively, ICT offers increased opportunities for sustainable economic development and plays a critical role in rapid economic growth, productive capacity improvements, education, government, agriculture and international competitiveness enhancement. The paper has pointed out that ICT has yet to make significant impact in most African countries due to lack of reliable and adequate electricity. Solar electricity has been seen as the most cost-effective way of generating electricity, especially in remote rural areas, for ICT devices. For the widespread of solar power generation in Africa, various strategies have been identified which include training of qualified solar engineers and technicians, establishing PV markets and business modes, introduction of solar energy education in schools and universities, political leaders appreciating solar electricity as one of the major energy component, lowering initial cost of the PV technology, availability of finance mechanisms for rural communities, import tax exemption and African countries regarding rural electricity as one of the basic needs. Practical implications – The paper shows that the problems of lack of qualified solar technicians and established PV markets and business modes (especially in remote areas), lack of solar energy education in schools have to be addressed before the benefits of ICT in Africa can be seen. Other issues include African countries appreciating solar electricity as one of the major energy component, lowering initial cost of the PV technology, availability of finance mechanisms for customers, import tax exemption and African countries regarding rural electricity as one of the basic needs like food, shelter and clothing. Overhaul of existing systems needs to take place in order to provide the means to deal with some of these issues. Originality/value – Availability of reliable electrical energy remains crucial for development of ICT in rural African countries. Solar electricity is clearly one of the most promising prospects to the grid electricity problem in African countries because most African countries lie in the sunshine belt. The paper raises awareness about this in a unique way and suggests some novel measures about increasing the availability of solar systems for solar power generation. It is anticipated that the increases in solar power generation, especially in remote areas, will increase the use and application of ICT in various sectors.

Purpose Every day, the sun provides by far more energy than the amount necessary to meet the whole world’s energy demand. Solar energy, unlike fossil fuels, does not suffer from depleting resource and also releases no greenhouse gas emissions when being used. Hence, using solar irradiance to produce electricity via photovoltaic (PV) systems has significant benefits which can lead to a sustainable and clean future. In this regard, the purpose of this study is first to assess the technical and economic viability of solar power generation sites in the capitals of the states of Canada. Then, a novel integrated technique is developed to prioritize all the alternatives. Design/methodology/approach In this study, ten provinces in Canada are evaluated for the construction of solar power plants. The new hybrid approach composed of data envelopment analysis (DEA), balanced scorecard (BSC) and game theory (GT) is implemented to rank the nominated locations from techno-economic-environmental efficiency aspects. The input data are obtained using HOMER software. Findings Applying the proposed hybrid approach, the order of high to low efficiency locations was found as Winnipeg, Victoria, Edmonton, Quebec, Halifax, St John’s, Ottawa, Regina, Charlottetown and Toronto. Construction of ten solar plants in the ten studied locations was assessed and it was ascertained that usage of solar energy in Winnipeg, Victoria and Edmonton would be economically and environmentally justified. Originality/value As to novelty, it should be clarified that the authors propose an effective hybrid method combining DEA, BSC and GT for prioritizing all available scenarios concerned with the construction of a solar power plant.


Renewable energy in the recent era world-widely has proven to be a major shift for clean energy generation. It is a great opportunity or solutions to address increasing clean energy demand especially in a developing country such as India. As wind energy and solar energy are most commonly used renewable resources, gives their abundance in the region. Focusing aim of the analysis is to present the reliability of pumped hydro storage (PHS) system with respect to battery banks on the basis of operation and maintenance (O&M) cost with minimum loss. Thus, this system will have feasibility and practical capability to provide persistent supply operation to remote areas. The Hybrid Optimization Model for Electric Renewable (HOMER) software also known as HOMER Prois used to conduct simulation of the system.

The main purpose of the study is to compare various factors that affect the development of the industry. The chapter analyzes the literature on various issues related directly or indirectly to the development of the industry. Several research methods are used: comparison of the influence of various factors on the price of solar electricity using the vector autoregression model (VAR model). The chapter describes the risks associated with competition (first of all, for the territories where solar panels are supposed to be located). The result of the chapter is a forecast for the supply of solar energy in the next 20 years. In the 21st century, the use of solar energy has become very popular, primarily due to the fact that solar power plants are least harmful to the environment, compared to other types of power plants. Recent research in the field of solar power engineering has shown that using carbon nanotubes will double the efficiency of power plants, breaking the Shockley-Queisser limit. Such technologies can make solar power the most used electricity in the world.

Meteorological data such as solar radiation (1975-1984, and 2002-2010) and sunshine duration (1968-2004) were analyzed to study temporal characteristics of solar energy and investigate solar energy potential in Kathmandu valley. Pre-monsoon and post monsoon seasons have higher mean monthly sunshine duration (about 8 hours/day) than summer (about 5 hours/day) and winter (about 7 hours/day) seasons over Kathmandu. Pre-monsoon and monsoon seasons receive solar energy of about 190 Wm-2 and 170 Wm-2 respectively. The winter season receives the least amount of solar radiation (135 Wm-2). Approximately 220 MW of solar electricity can be produced in Kathmandu that will substantially fulfill current energy demand and reduce environmental pollution in the valley by replacing fossil fuels with clean solar electricity.Journal of Hydrology and Meteorology, Vol. 8(1) 2012, p.77-82
