SITE REVIEW: ThetaNoon - Global Solar Systems Tracking

Hi all,
A first version of ThetaNoon is available at:
http://thetanoon.appspot.com/

ThetaNoon is a service that allows solar systems (solar panels, water heaters etc.) owners track their systems output. It is also valuable for anyone looking to buy solar systems and wants to learn how this systems work, what is their output, etc, from current solar system users.
I tried to give the service more of an 'application' feel, rather than a website.

The current functionality is pretty basic, there is no update mode yet, but as more systems are added, it will become very useful.

I used GWT + EXT to develop the UI part, and the data services (system calculated output,chart data etc.) is run on Google's app engine. The GWT front-end calls GAE web-services that provides the data foundations.

Any input would be highly appreciated - I am sure you will have a lot to suggest.

Thanks,
Yossi

That is really cool. Interesting look, it appears like an application. Very cool indeed! That should do well
