Research Paper (postgraduate) from the year 2018 in the subject Engineering - Power Engineering, , language: English, abstract: Electricity is an essential thing for a human life as it influences every part of people's lives and it is important to the effective functioning of a healthy economy and to ensure a healthy population. However, there are still millions of people deprived of electricity, most of them in the rural areas where electrification experiences challenges such as low profitability, high economic investments or difficulty of operation, among others. At the moment, solar energy has turned into a popular and meaningful alternative energy source to meet specific demands around the world due to the climate change and global warming caused by non-renewable energy resources. The aim of this project is to develop a simple and cost-effective Photovoltaic (PV) system for the rural regions where grid electricity is not available. Specifically, the study will focus on the development of PV system in Kitui County. The research will use both quantitative and qualitative approaches to collect the relevant data. This proposed project will help improve the access and transmission of electricity in Kitui County; thus, enhancing the lives of people in the region.

The energy situation in developing countries is desperate.Because these countries are primarily dependent on fossil fuels--chiefly oil--for industrial growth, they have been hard hit by oil price increases. Further, in the rural areas, where most of the population lives, there are limited supplies of increasingly expensive diesel fuel or kerosene. Noncormzercial energy sources such as firewood, dung, and agriouZtural residues are generally used in rural areas, but under the pressure of growing populations the forests are disappearing. This is resulting in a critical shortage of firewood for cooking and heating, as well as in the destruction of the environment. In addition, when dung and agricultural residues are burned, valuable fertilizers are destroyed. Thus, the rural areas--the sources of food and fiber--face a particularly alarming situation.

This book describes recent breakthroughs that promise major cost reductions in solar energy production in a clear and highly accessible manner. The authors address the three key areas that have commonly resulted in criticism of solar energy in the past: cost, availability, and variability. Coverage includes cutting-edge information on recently developed 40 efficient solar cells, which can produce double the power of currently available commercial cells. The discussion also highlights the potentially transformative emergence of opportunities for integration of solar energy storage and natural gas combined heat and power systems. Solar energy production in the evening hours is also given fresh consideration via the convergence of low cost access to space and the growing number of large terrestrial solar electric power fields around the world. Dr. Fraas has been active in the development of Solar Cells and Solar Electric Power Systems for space and terrestrial applications since 1975. His research team at Boeing demonstrated the first GaAs/GaSb tandem concentrator solar cell in 1989 with a world record energy conversion efficiency of 35, garnering awards from Boeing and NASA. He has over 30 years of experience at Hughes Research Labs, Chevron Research Co, and the Boeing High Technology Center working with advanced semiconductor devices. In a pioneering paper, he proposed the InGaP/GaInAs/Ge triple junction solar cell predicting a cell terrestrial conversion efficiency of 40 at 300 suns concentration. Having become today’s predominant cell for space satellites, that cell is now entering high volume production for terrestrial Concentrated Photovoltaic (CPV) systems. Since joining JX Crystals, Dr. Fraas has pioneered the development of various thermophotovoltaic (TPV) systems based on the new GaSb infrared sensitive PV cell. Dr. Fraas holds degrees from Caltech (B.Sc. Physics), Harvard (M. A. Applied Physics), and USC (Ph.D. EE).

This study presents options to fully unlock the world’s vast solar PV potential over the period until 2050. It builds on IRENA’s global roadmap to scale up renewables and meet climate goals.

Presenting a complete guide for the planning, design and implementation of solar PV systems for off-grid applications, this book features analysis based on the authors’ own laboratory testing as well as their in the field experiences. Incorporating the latest developments in smart-digital and control technologies into the design criteria of the PV system, this book will also focus on how to integrate newer smart design approaches and techniques for improving the efficiency, reliability and flexibility of the entire system. The design and implementation of India’s first-of its-kind Smart Mini-Grid system (SMG) at TERI premises, which involves the integration of multiple renewable energy resources (including solar PV) through smart controllers for managing the load intelligently and effectively is presented as a key case study. Maximizing reader insights into the performance of different components of solar PV systems under different operating conditions, the book will be of interest to graduate students, researchers, PV designers, planners, and practitioners working in the area of solar PV design, implementation and assessment.
