Re: [hreg] Re: Uni-Solar Film Laminate and Wind Energy Testing for Greater Houston
- As far as the wind turbines go, Houston probably isn't a good bet. I run a small wind and pv installation company out of Galveston, and although I do install wind products along the coast, I feel I'd have a hard time justifying a wind project in the Houston area. This is just based on a small wind turbine in an urban environment. Of course, if you get the turbine a considerable height in the air, it may work just fine. Even on top of tall commercial buildings may prove suitable.Regards,Justin Owens

I felt the same wayafter studying it awhileAlso, is Houston good for wind turbines?The wind blows alot in the galleria butnot sure if it would be better than the PVmethodI guess I need to do some sort of wind testRay

Does anyone know of any wind energy system tests that
relates whether a solar energy system productive enough
compared to a residential wind energy system?
Also, has anyone in the Greater Houston area tested or installed the
Uni-Solar Thin Film Laminate on roof tops? and if yes, how does it
rate for hail and over-all roof top heat ... as I noticed it has a maximum
roof heat limit of 185 F ... (I haven't tested but it seems to me our roofs
may be hotter than that at times )
Your feedback is appreciated

Tracking usually adds 30-35% efficiency.
The general opinion in this group seems to be that tracking isn't worth the cost; your money is better spent on adding more panels and just brute forcing it. I tend to agree with this.
In a residential application, the roof top is wasted space, panels are a great use for it. Unless you can use a nice tracking array to add architectural interest to a landscape or garden, it seems like a mis-use of land. But they are kinda impressive looking as an accent feature; could replace a birdbath or statue.
Tracking arrays are just one more thing to go wrong, and I have doubts how they would do in a hurricane. I am (always) optimistic that some awesome engineer will build a better one some day.
