Limited availability of grid-based electricity is a major challenge faced by many developing countries, particularly the rural population. Fuel-based lighting, such as the kerosene lantern, is widespread in these areas, but it is a poor alternative, contributing to global warming and causing serious health problems. Several developing countries are therefore now encouraging the use of sustainable lighting. Solar Lighting gives an in-depth analysis of energy-efficient light production through the use of solar-powered LED systems. The authors pay particular attention to the interplay between energy transformation and device efficiency. They also discuss diverse aspects of renewable energy, including how an improvement in the efficiency of appliances can reduce the cost of energy. Solar Lighting is written for physicists, environmental experts and lighting engineers. It is also suitable for undergraduate students in the fields of environmental science, electrical engineering and renewable energy.

Howard Teich has discovered a brilliantly simple and invaluable way of helping men and women move towards wholeness and healing. With vivid examples from his therapeutic practice and from his own life, Solar Light, Lunar Light presents Teich's pioneering development of the solar/lunar polarity, and his sharp distinction of this from the masculine/feminine polarity with which it has long been uncritically and often destructively conflated. Recognizing this distinction, and moving towards a deep integration and rebalancing of the solar and lunar principles, represents a crucial task not only for every individual but for our civilization. --Richard Tarnas, Professor of Philosophy and Psychology, California Institute of Integral Studies, Author of The Passion of the Western Mind and Cosmos and Psyche--- This is a significant, life changing book. Howard Teich's work is crucial to understanding and healing the damage our rigid ideas of gender have done to us all, women and men alike. This is a book that can change how you see every problem you encounter and point you toward deeper more creative responses. Here is a psychology that has the potential of restoring us all and our world to wholeness. ---Susan Griffin, author of A Chorus of Stones and Woman and Nature--- The perception that masculine and feminine traits represent oppositional forces has contributed to a long history of personal and cultural dysfunctions. Through a skillful interweaving of modern psychology, mythology and ancient history, Howard Teich, PhD offers a thought provoking thesis that these polarizing traits are actually cooperative partners in evolution s dynamic dance. Solar Light, Lunar Light is a healing journey that encourages readers to transcend misperceived limitations so that we may write a new empowering chapter in human evolution. --Bruce H. Lipton, Ph.D., Cell biologist and bestselling author of The Biology of Belief: Unleashing the Power of Consciousness, Matter and Miracles.

Solar energy is expanding worldwide and becoming an increasingly important part of the energy mix in many countries. Solar energy is used all over the world, but in terms of total installed solar capacity, India, China, Japan, and the United States are now top of the world. Solar panels can create power almost anywhere on the planet. However, some regions receive more sunshine than others and hence have a greater solar energy potential. It is based on insolation, which is a measurement of how much solar radiation reaches a specific area on the earth's surface. Solar energy can be captured in a variety of ways. Photovoltaic solar panels are the most frequent method. Photovoltaic (PV) devices use semiconductors to generate power directly from sunlight. Photons impact and ionize semiconductor material on the solar panel as the silicon photovoltaic solar cell absorbs solar energy, causing electrons to break free of their atomic bonds. A flow of electrical current is created when electrons are compelled to move in one direction. Only a portion of the light spectrum is absorbed, while the rest is reflected, too faint (infrared), or generates heat rather than electricity (ultraviolet). Concentrated solar power is the second type of solar energy technology (CSP). Solar thermal energy is used in CSP facilities to create steam, which is subsequently turned into electricity via a turbine. The global solar energy installed capacity is estimated to reach 1,645 gigawatts (GW), registering a CAGR is 13.78%. The growth of the solar energy market is driven by an increase in environmental pollution and the provision of government incentives & tax rebates to install solar panels. In addition, a decrease in water footprint associated with solar energy systems has fueled their demand in power generation sectors. The demand for solar cells has gained major traction owing to a surge in rooftop installations, followed by an increase in applications in the architectural sector. Furthermore, the demand for parabolic troughs and solar power towers in electricity generation is expected to boost the demand for concentrated solar power systems. Only the two commonly recognized kinds of technology for converting solar energy into electricity — photovoltaics (PV) and concentrated solar power (CSP, also known as solar thermal) — are considered in their current and possible future forms in The Future of Solar Energy. Expanding the solar sector considerably from its current small size may result in developments that no one can predict right now. Solar deployment in the future will be highly influenced by uncertain future market conditions and public policies, including but not limited to measures aimed at mitigating global climate change. The book covers a wide range of topics connected to Solar, as well as their manufacturing processes. It also includes contact information for machinery suppliers, as well as images of equipment. A complete guide on Solar PV Power and Solar Products manufacture and entrepreneurship. This book serves as a one-stop-shop for everything you need to know about the Solar, which is ripe with opportunities for manufacturers, merchants, and entrepreneurs. This is the only book that covers Solar PV Power and Solar Products in depth. From concept through equipment procurement, it is a veritable feast of how-to information.

Solar Cells and Light Management: Materials, Strategies and Sustainability provides an extensive review on the latest advances in PV materials, along with light management strategies for better exploiting the solar spectrum. Following a brief review of the current status of solar cells, the book discusses different concepts, principles and technologies for solar devices, starting with standard silicon cells and then covering organic-hybrid, DSSC, perovskite, quantum dots and nanostructured oxide solar cells. Other sections focus on light manipulation and spectral modification, materials for spectral conversion, and environmental and sustainably considerations. An emergy analysis, which is an extension of the Life Cycle Assessment methodology, is applied to the study of solar PV systems, thus allowing for effective integrated indicators.
