Product Description

As environmental concerns have focused attention on the generation of electricity from clean and renewable sources wind energy has become the world's fastest growing energy source. The Wind Energy Handbook draws on the authors' collective industrial and academic experience to highlight the interdisciplinary nature of wind energy research and provide a comprehensive treatment of wind energy for electricity generation.

Features include:
– An authoritative overview of wind turbine technology and wind farm design and development
– In-depth examination of the aerodynamics and performance of land-based horizontal axis wind turbines
– A survey of alternative machine architectures and an introduction to the design of the key components
– Description of the wind resource in terms of wind speed frequency distribution and the structure of turbulence
– Coverage of site wind speed prediction techniques
– Discussions of wind farm siting constraints and the assessment of environmental impact
– The integration of wind farms into the electrical power system, including power quality and system stability
– Functions of wind turbine controllers and design and analysis techniques

With coverage ranging from practical concerns about component design to the economic importance of sustainable power sources, the Wind Energy Handbook will be an asset to engineers, turbine designers, wind energy consultants and graduate engineering students.

Excellent and in depth
 
Review Date: May 19, 2003
Reviewer: ,
This book was written by people who spent their lives for something they loved. Their passion is evident from the in depth analysis and their personal contribution to many aspects of the presented theory.
This book is highly recommended to engineers and students, however it might not be very useful to people with limited engineering knowledge.
And a personal comment: If you are a Mechanical, of Aeronautical engineer fascinated by aerodynamics, David Sharp's section will surly challenge and intrigue you...
Excellent Reference for Acedemic and Professional Engineering
 
Review Date: January 16, 2008
Reviewer: M. McWilliam,
I have read many similar books, I have also read much of the latest literature on wind turbine aerodynamics. Thus, I can say that of all the books written on wind turbines this book is written at the highest level. Much of the content within this book reflects what is best theory for practicle wind turbine engineering. Very indepth analysis of the aerodynamics and explains a lot of the concepts in great detail, where other books will gloss over. There are some things that readers should be aware of, first this book is only for people serious about wind turbine engineering. It is written at a level where some engineering knowledge is needed. I would recomend it for graduate students and proffesionals, but not for part time enthusiasts and hobyists.
A must in your Wind Energy Collection

Reviewer: Santiago Paredes Pinzón, Colombia
For anyone interested in wind energy this book is a must. When first take a look at the book you get pretty scared but just let time go by while you get acquainted with more topics dealing with wind energy and you'll love it. The only thing left to say is thanks to the authors. the more you think you know about something the more you realise that you're not even half way there....
Great! The book came early and in great condition

Reviewer: fluff,
Trustworthy, good condition and the book came early.
The book is a birthday present for a friend. According to my friend, the information is very useful to get an idea of wind turbine design.

Product Description

Representing the next generation of solar panel technology, the Solaris 26 maximizes performance while taking up virtually no space at all. The unit's multi-section design folds up into a compact footprint that's just a bit larger than a DVD case, while still delivering an impressive 26 watts of power, more than enough to charge a laptop or digital video camera or power a satellite or cell phone. In addition, the unit's high-performance CIGS solar cells--the most efficient thin-film solar technology available--are extremely reliable, with a design that instinctively converts incident sunlight into an electrical current, even in low-light conditions. The combined functions make this an ideal panel for camping trips, hikes, power outages, and other occasions when it helps to have a portable power source on hand.

The Solaris 26, which measures 21.5 by 37.5 inches when open and 11 by 8.5 inches when folded, includes a battery clamp cable for charging car batteries, along with vehicle outlet and multi-linking cables. It's also backed by a one-year warranty.

What's in the Box?
Solaris 26 foldable solar panel, vehicle outlet cable, multi-linking cable, battery clamp cable, storage sack, user's manual.

Flexible Power for New or Existing Systems
The Sunforce 39810 80-Watt High-Efficiency Polycrystalline Solar Panel Module is an ideal addition to both new and existing solar power systems. It comes with a voltage tester, wiring and mounting accessories to make installation easy. These solar panels can be used individually, or they can be connected together to boost power output.

Sunforce High-Efficiency Polycrystalline Solar Panels must be connected to a compatible charge controller (sold separately). The charge controller prevents the solar panel from overcharging and damaging connected batteries or electrical systems. It also prevents reverse current from sapping your battery strength at night. Sunforce High-Efficiency Polycrystalline Solar Panels can be connected in parallel for 12-Volt systems, or in series for 24- and 32-Volt applications. Please ensure that the components being used in your system are compatible with the individual and total output voltage of your solar panels.

About Polycrystalline Solar Power
Polycrystalline silicon is a material consisting of thin wafers that are cut from a silicon crystal which has grown in several directions. This advanced surface texturing process provides polycrystalline solar panels with a higher power output than amorphous panels of the same dimensions, and makes them more cost and space-effective. These individual wafers are assembled into panels that are covered by durable, weatherproof tempered glass. Thanks to their efficiency and durability, these solar panels require virtually no maintenance once installed. This solar panel has a maximum power output of 80-Watts/4.67-Amps.

Solar panels convert sunlight into an electric current; they do not actually store power. Sunforce Solar Power Panels are primarily used to recharge all types of 12-Volt batteries, including lead-acid automotive batteries, deep-cycle (traction type) batteries, gel-cell batteries, and heavy-duty (stationary type) batteries. When using these solar panels to run appliances on a regular basis, the use of deep-cycle marine batteries is recommended. This type of battery is designed to withstand the frequent charge and discharge cycles associated with solar panel use.

Product Details

  • Advanced polycrystalline design is highly efficient and provides superior power output
  • Maximum power output: 80 Watts/4.67 Amps
  • Multiple panels can be connected together for even more power
  • Easy to install and virtually maintenance-free
  • 25-year warranty
