Bad all around

Pros: The birds like sitting on it when it isn't turning.

Cons: low output, poor customer service, broken

I purchased a Windspire a few years ago. I've never been happy with the power output. Since then I have been through 2 inverters and due to a faulty shorting clip, the unit sheered off in high winds and the top had to be replaced. The last episode was once again after some heavy winds and the brake wouldn't kick off. After waiting several months for a replacement inverter, I installed it and...

Southwest Windpower Skystream 3.7 Residential Wind Generator

9 Reviews

“Over all I am extremely happy with my Skystream 3.7. I installed it in back in September of last year 2007. Initially I had a problem that arose two months after I installed it. It had a software problem that shut the machine down for over a month and a half, but Southwest Wind Power switched it out with a new Skystream turbine and it has been running great ever since. I installed the...” --joshuajanes

“ Check the web site at www.mariahpower.com - unless you are in an area with exceptional wind speeds the output is minimal. At 5 m/s (12 mph) wind speed the puts out between 100 and 150 watts. Using the commercial capacity factor of approx 0.35 (say 150*8760*.35/1000) you may reach 500 kWh annual production. The unit base price is about 6,000 USD plus what ever else is required. The projected...” --Russ

“ Even iin higher winds, it didn't produce significant power, although it responded well in lower winds. When connected along with other products, such as solar panels, it doesn't produce after the panels are producing a higher charging rate. A panel of 300 watts produces more charging power than this unit. My panels produce over 12 amps of charging power. It is produced in China, so...” --chico4

“We have a 4kW array made up or 20 of these 200W panels. The system powered on in November 2007 and has been working great, even here in the rainy NW corner of Oregon. You can see the system's performance in near real-time here: http://tinyurl.com/2vxq37 Now, in early April, it is generating power from 8AM till 8PM. By using these higher efficiency panels, we were able to buy fewer...” --celticsolar

“This was part of my lovely prize pack, so I really want to be able to write up a glowing report. However, this is only the begining of my review...as I have not successfully used the solio yet!! We took it with us on our trip to Canada. I charged the thing up, no problem. However, I didn't realize that if I wanted to use the solio, I needed to bring a cord with me (the instructions are...” --nitedreamer

Windmax 500W Hybrid Wind Turbine

2 Reviews

“I purchased this system a couple months ago so I have had time to see how it works. When there is enough wind it works great but in low wind conditions it actually drains power from the batteries. For instance, my solar panels had my batteries full and it was dumping into the loader when a slow wind came up and immediatly stopped the dumping. Within a few hours my batteries were nearly dead!...” --milldrain

“I had a great experience buying RECs through VGE. The site was intuitive and I quickly received a package from them with a decal and a certificate recognizing my contribution. At least for me, the value proposition of RECs is easier to understand than Carbon Offsets. In states where major utilities are required to purchase some of their power from renewable sources, if enough people purchase...” --Deej

“I bought two of these 50-watt panels as an add-on to my "Supplemental Solar" system at my home. They produce a nice amount of electricity and the price was reasonable (recently saw the price had come down $13 where I bought them - mrsolar.com. I had to wire the positive and negative leads myself as there were no MC cables or anything included with them. That wasn't too much of...” --mikebeavis
