application. There is a minor learning curve associated with it (including
locating your array to the proper location using Google Earth) but I have been
very pleased with the results. It isn’t a simple calculator but it is a
powerful and free tool.<o:p></o:p></span></p>

We have a spreadsheet on our web site that calculates inter-row spacing for
south facing rows on flat or angled surfaces: <a
href="http://millersolar.com/resources/resources.html">http://millersolar.com/resources/resources.html</a><br>
<br>
You have added a new twist that has us momentarily stumped -- non-south facing
rows. I am working on a solution and I will add it to the spreadsheet as
soon as I figure it out.<br>
<br>
There is a manufacturer that had a super excel spreadsheet to calculate
inter-row shading, complete with nifty graphics, but I forget now
where-in-the-web it is. Anyone else remember this one?<br>

PS: I have had a lot of comments from around the world of those using our
design tools and even a few that added some ideas. Our thanks to all who
have helped and commented.<br>

Someone posted a website or calculation for determining the spacing between
solar arrays, but I can not find it. It is easy to get the spacing from a
drawing when the array faces true south, but when the array faces southeast or
southwest is what we need to know. Please help. Thank you very much.<br>
