[Equest-users] Solar panels

[Peter Hillermann]

Alan,

 

Solar panels are tough. I use Ecotect to check the solar reflectance and
solar gain of a specific item. You can set individual planes to different
sets of properties and watch the reflection of sun rays. It also helps with
shadow studies (Parapets, roof top equipment, buildings near by). There is a
button called solar exposure which is really what you are looking for. 

 

I have never done solar panels in eQuest. Also when filling out the LEED
form we used calculated method. I would check into a software that studies
solar exposure or just use PV Watts calculator. I don't really understand
the reflectivity of the roof as it relates to solar panels, but then again I
love to learn.

 

Thanks,

 

PETER HILLERMANN

I need to have about 5000ft of roof space dedicated to solar panels on a
41000ft roof.  How can I model 5000ft of roof to be 100% reflective?
