Eclipse Solar Backpack - Camo
Take your mobile devices off the grid with the new Eclipse Solar Backpack. It is the first in a line of solar bags now made in the USA! This backpack combines the traits of a top quality bag with a new, powerful, thin-film solar module. The backpack features multiple organizer pockets for your smart phones, iPods, and accessories. The rear of the backpack features a separate padded laptop cavity. External side mesh pockets can be used for a water bottle holder or other items for quick access. The pack features a large main cavity for books or extra clothing when traveling. The front zippered accessory pouch includes pen holders, cd holders, and a removable clip for USB memory sticks or keys. The light-weight, flexible, thin-film solar charging module provides up to 4 Watts of power to charge your handheld electronics quickly and efficiently. Using a cell phone as an example, you can trickle charge the cell phone battery during casual commutes or long hikes with the backpack using a standard 12V cigarette lighter cord (not included). The result is an extension of battery life, and a source for charging when traveling in remote areas where traditional charging sources are not available, and in emergency situations. See our Portable Powerpack (universal USB battery) for additional power storage.

Wind and Solar Power Systems: Design, Analysis, and Operation, Second Edition
The search for clean, renewable energy sources has yielded enormous growth and new developments in these technologies in a few short years, driving down costs and encouraging utilities in many nations, both developed and developing, to add and expand wind and solar power capacity. The first, best-selling edition of Wind and Solar Power Systems provided the most complete and modern treatment of renewable energy. This second edition continues the tradition by offering updated and expanded coverage of this growing field.The book begins with individual sections devoted to wind power and solar photovoltaic technologies, their engineering fundamentals, conversion characteristics, operational considerations to maximize output, and emerging trends. The discussion of wind power includes the theory of induction machine performance and operation as well as generator speed control, while the solar PV section includes array design, environmental variables, and sun-tracking methods. This edition includes two chapters devoted to new and specialized technologies. The third section explores large-scale energy storage technologies, overall electrical system performance, and total plant economy while the final section explores ancillary power systems derived from the sun.Focusing on the complete system rather than on a single component, Wind and Solar Power Systems: Design, Analysis, and Operation, Second Edition offers the most comprehensive reference to all aspects of modern renewable energy systems.
Grid Converters for Photovoltaic and Wind Power Systems (Wiley - IEEE)
Grid converters are the key player in renewable energy integration. The high penetration of renewable energy systems is calling for new more stringent grid requirements. As a consequence, the grid converters should be able to exhibit advanced functions like: dynamic control of active and reactive power, operation within a wide range of voltage and frequency, voltage ride-through capability, reactive current injection during faults, grid services support.This book explains the topologies, modulation and control of grid converters for both photovoltaic and wind power applications. In addition to power electronics, this book focuses on the specific applications in photovoltaic wind power systems where grid condition is an essential factor.With a review of the most recent grid requirements for photovoltaic and wind power systems, the book discusses these other relevant issues:modern grid inverter topologies for photovoltaic and wind turbines islanding detection methods for photovoltaic systems synchronization techniques based on second order generalized integrators (SOGI) advanced synchronization techniques with robust operation under grid unbalance condition grid filter design and active damping techniques power control under grid fault conditions, considering both positive and negative sequences Grid Converters for Photovoltaic and Wind Power Systems is intended as a coursebook for graduated students with a background in electrical engineering and also for professionals in the evolving renewable energy industry. For people from academia interested in adopting the course, a set of slides is available for download from the website. www.wiley.com/go/grid_converters
