Strut Spacing and Pricing

Solar strut provides the foundation between the roof and solar array.  It is important to first draw and chalk out the layout then proceed to rafters.  Most homes are either built with a 16 ir 24 " distance between the two rafters.  Most spacing is done by using every other rafter or a 32 to 48 inch span.  This distance provides support for the array without comprimising and windload issues.  Solar strut is expensive and should be used prudently.  I learned this the hard way.  I was overy concerned with the wind loads so I spaced the strut every 24 inches and it cost an extra 1000 dollars.  I nearly lost my job, but rather took a pay cut. 

In the end, solar strut provides  a solid bond between the  roof with the array, but can put a damper on costs.
