[RE-wrenches] orientation data

[Ryan Mayfield]

Nik,

 

Check out this tool on Solmetric's website:
http://www.solmetric.com/annualinsolation-us.html

 

You can input your tilt and azimuth and it calculates the percentage loss
from the site's ideal orientation.

Hey Folks,


Anybody have real data to compare productions for south-facing vs,
west-facing PV array? PVWatts is only showing about a 7% derating for facing
west. 

 

Thanks,

Nik
