Practical Photovoltaics, the now-classic reference on solar electricity, offers a unique combination of technical discussion and practical advice. Physicist, lecturer, and solar-home dweller Richard Komp explains the "how" and the "how-to" of PV, while providing valuable information on the industry, new developments, and the future. The book is a comprehensive guide to the theory and reality of solar electricity, as well as a detailed installation and maintenance manual. A well-illustrated appendix offers step-by-step instructions for constructing your own solar module, a creative approach to demystifying the technology. Presented in a clear, concise, and understandable style, Dr. Komp's contribution to PV literature has been called the "best single reference available," "the easiest and most complete education on photovoltaics," "one of the best basic books on PV," and "the best of the books."

From Space to Earth tracks the evolution of the technology of photovoltaics, the use of solar cells to convert the sun's energy into electricity. John Perlin's painstaking research results in a fascinating account of the development of this technology, from its shaky nineteenth-century beginnings mired in scientific controversy to its high-visibility success in the space program, to its current position as a versatile and promising power source.
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.
So, you're looking into building homemade DIY wind turbines and saving energy, saving money, and even getting off the grid. There are some great wind turbine DIY books that talk about hand carving blades out of wood and how to make your own generator from scratch. This includes even winding your own coils, welding , etc. This is cheap but not very simple. Not simple at all. I will teach you how to make it simple and cheap.I believe there is too much waste in the world right now. I love the concept of taking something labeled as "junk" and making it new again (upcycling). I hate to see batteries go to scrap when it is easy to get some more life out of them. Imagine all that lead and sulfuric acid has to go somewhere and I'm always afraid it will impact the environment or the water supply.animated windmillI wrote this book for the thrifty person and the "upcycler". Someone who wants to get started into resinential wind power and not break the bank in the process. Someone who hates to see scrap sit around and go to waste. Someone who wants to become independent and off the grid and help the environment. Some people even buy this book so they can refurbish forklift batteries as a business. Imagine getting a free forklift battery that normally costs $4000 new. You recondition it in 30 days and sell it locally for $1500. Some people even take the individual cells out of the forklift batteries to sell seperately. A single cell can cost $400 or more. But you could sell them for $100 each and make huge profits. People need 6 of them, at least, to make 12 volts. And, the best part, you don't even need a truck to do it. I'll show you how to have the batteries dropped off and picked up.This e-book is full of pictures and diagrams to explain the concepts. In it I cover the following and a lot more: * how to make FREE homemade wind turbine blades and it will only take about an hour to finish a set of 3. * a page full of equations and examples of how to use them to figure out power, rpm, tsr, windspeed etc. (units are in miles per hour and feet) * how to find FREE fork lift batteries and how to make them as good as new * making a homemade de-sulfator so you can "pulse" any lead acid or ni-cad battery back into new condition * what kind of generator to look for and how to get the best prices * how to make a simple "furling" system to protect the windmill in high winds * how to charge several banks of batteries all at once while pulsing them back to health * How to make a 1,000 watt wind turbine for less than $150 (including tower) * How to make a 3,000 watt wind turbine for about $220!
