Although the standoff mounting method is the least expensive and simplest choice, there are many instances where it is not practical.  Standoff mounting becomes impractical where mounting brackets cannot be directly centered on rafters, or where mounting hardware must penetrate tile roofs.  For such situations, SunEarth has developed it's own proprietary SolarStrut structural mounting and racking hardware.  At the heart of every SolarStrut installation is the extruded structural channel and sliding nut assembly, which allow for ultimate flexibility in rack construction.  All SolarStrut components are manufactured from bronze anodized aluminum and utilize stainless steel fasteners to provide galvanic compatibility with all SunEarth collectors and the ultimate in strength and corrosion resistance.
     SolarStrut can be suspended from the roof surface using short footing sections (shown above), or through the use of hangar bolts that are ideal for tiled roof applications (illustrated below).  In addition to solar-thermal collectors, SolarStrut provides an ideal and extremely cost effective way to mount PV modules.
