Review Date: April 19, 2009
Reviewer: Ed M. Courtney, Jr.,
Sunsei CC-25000 25-Amp Solar Panel Charge Controller For SE-16000, and SE-24000 #11101 I ordered the unit from Amazon, received it a day earlier than promised and installed it the next day. The installation was simple, involved drilling one hole for wiring to route wires into my Travel Trailer, and fishing wires through hole.(I already had wires as I have five year old Sunsei solar panels). I furnished two wood screws to mount the unit to the wall and believe they will hold as the unit is lightweight. The unit worked correctly immediately and the instructions on operation are clear. The only area of concern is all the wire attachment points resemble stereo speaker attachments from which wires detach too easily no matter how tight you get them. At least I will know immediately where the problem is if I have a short. Keeping my fingers crossed and may not be a problem.

Product Description
Wind power is developing rapidly, both in the number of new installations and in the interest from various stakeholders including policy makers, NGOs, research scientists, industry, and a broader general public. Unlike the majority of other texts on wind power, which are written primarily for engineers or policy analysts, this book specifically targets professionals and students interested in wind power project development.
Having outlined wind power basics and explained the underlying resource and technology, the author explores the interactions between wind power and society and the main aspects of project development, including, siting, economics, and legislation.
Based on a successful Swedish edition, expanded and updated for an international market, this book will be an essential reference for professionals developing new sites, government officials and consultants reviewing related applications, and both specialists and non-specialists studying wind power project development.

Objective and Comprehensive
 
Review Date: April 4, 2008
Reviewer: Jorge De Rosa Ferreira, Rio de Janeiro, RJ Brazil
Professor Wizelius presents an objective approach to Wind Power Projects and fundamental concepts. The book covers some important Wind Power aspects from A to Z - from technical issues to project development and commercial feasibility analysis. I strongly recommend this book to any one interested in the Wind Power or Renewable Energy business.
Simple and to the point to help explain complex terms and information to simplerer audiences
 
Review Date: August 9, 2009
Reviewer: Jc Lech,
When I ordered this book and looking at the price I was skeptical as to whether it would deliver the value it proposed. After reviewing and reading it is a great addition to Paul Gipe's book wind power. Paul Gipe's book goes into heavy reading and detail which is super, for for a summary book and helping fill in the gaps and present information to your employees and audiences in a simple real practical terms this book is a super and great asset. There are great pictures, tables and illustrations. Additionally, it is well written and easy to comprehend.
Gide for practical work in wind project development
 
Review Date: December 8, 2009
Reviewer: Miodrag Zlatanovic,
Very useful book. Not only for students at different levels, but also for the engineers working in wind project development. This book is recommended also for persons living in countries with non developed wind power to get the information how to support the idea on wind power introduction.
Comparative analysis of the measures that act as a driving force or a barrier for wind power development is of practical importance. The discussion on the environment impact of wind power projects is detailed as well the spatial planning recommendation.

Great Price!
 
Review Date: August 5, 2008
Reviewer: NoFear, CA USA
This product is by far the best price for what you get. I bout the Sunforce 50032 15 Watt Solar Battery Charger for 99.99 which is about $6.66 for each watt. With this product im only paying $5.46/watt. It is a little pricey if your only maintaining batteries but im actually running my mini frige off this and a semi truck battery. This unit produces exactly what is specified. Unit arrived at my doorstep 2 days after I ordered it, using ground shipping. Solar panel is inside retail box very securely, and is then put into a shipping box with packing peanuts. I would doubt it would break unless some serious damage was done to the box. Very pleased with my purchase.
