If you are using Sketchup for solar, you should be using the Skelion plugin. It will compute and draw the solar modules on any surface based on your preferred module, tilt angle and azimuth. We do all our quotes this way. ___ List sponsored by Home Power

[RE-wrenches] Spacing between ground mounted sub-arrays at 48.5 degrees N latitude

2014-02-16 Thread Bob Clark
Wrenches: I have a customer who wants 40 solar modules on ground mounts (not poles) in an area that slopes to the ESE at 7 degrees. Putting these modules on one ground mount assembly so that the modules are in a 0 degree slope East to West would leave the east end about 20 feet in the air.

I use Sketchup for these calculations now. It will do real shadows at any time of any day you want. If you are not familiar with it, send me the exact Google Earth coordinates and I will mock something up for you. On Sun, Feb 16, 2014 at 5:35 PM, Bob Clark bcl...@solar-wind.us wrote: Wrenches:

I second Chris's suggestion of Sketchup. Its very easy to use and does a great job modeling stuff like this. There is a free version from Google that is more than adequate for this. Good luck. On Sun, Feb 16, 2014 at 3:08 PM, Chris Mason cometenergysyst...@gmail.comwrote: I use Sketchup for

I third the use of Sketchup. I use it every day from design, to presentation, to permitting, to construction documents. Below are links to a few images of a recent 3D model I did. The goal here was to have a 10 degree tilt angle and have no shade on the next row on December 21 at 9:00am. Turns

I did a 246 kW ground mount installation in Simi Valley with an 11 degree slope ESE... Same issue as what you are facing. You can easily see the system from satellite images: ~1 mile north of HWY 118 at Kuehner Dr exit in Simi Valley, CA. We used Unirac's ULA rack system with 40 rack
