Made of ABS Plastic. Features Super Bright 1-Watt 2X LED. 11 continuous years of burn time on LED or 22 years of burn time when in the on position only at night. 8 hours charge in sunlight or room light will provide up to 10 hours of continuous light - can be charged over and over again. Holds a single charge for over 3 years and comes fully charged. Does not need to be stored in the sun - throw it in your glove box or drawer and three years later, just turn it on. Back up battery has a 7 year shelf life. Roll it up in a sleeping bag and forget you own it - turn it on 7 years later; then simply put it in the sun or room light for a day and have a 3 year solar charge again. Features power source indicator lights - red light is charging, yellow light is solar power, and green light is back up battery power. Treat it like a regular flashlight as it is always ready to go because it's always gathering light (recharging). You won't need to replace batteries that cause landfill pollution. Hybrid Solar Lite is 100% water proof up to depths of 80 ft. and it floats. Extreme temperatures do not affect the light - very durable and guaranteed for life. 4.75 in. L x 1.875 in. W x 10.25 in. H ( 0.35 in.)

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.
