Technology
ISA’s patented and patent-pending technologies have been employed to provide its customers the benefit of these unique solutions.
Tiltable Array
The only commercially available roof mounted array that has a built-in tilt capability that allows the array to be tilted up so you can reroof under it. No panel removal is necessary. Its balanced support structure allows easy tilting within seconds for a 24-module array.
CSS-20 Service Position 
CSS-20 Operating Position Central Support System
The Central Support System (CSS) requires only one major support instead of two – on the same beam structure with no increase in beam stress. Additionally the central support allows the bottom members of the truss can be lighter since their main stress is tension rather than compression.
The CSS technology also takes into consideration the bending and twisting due to wind for a single support mount and minimizes potential roof beam stress by offset positioning of the solar array with respect to the central support to substantially reduce associated stresses in the roof beams.
Windload Beam Clamp
The beam clamp was developed so that it could be deployed from above the roof without the need to go inside the building. Opening of the clamp is accomplished through its unique pivoting action. And its unique scissor clamping linkage provides a locking action that will not allow the clamp jaws to slip away from the beam once it is clamped in place. The CSS beam clamp that connects directly to major roof beams is able to withstand much higher loads than is possible with conventional beam clamps. This is accomplished by the blocking design of the beam clamp, which integrates the clamp structure with the beam to essentially react to loads as one structure.
Sure Grip Beam Clamp Angle Nut
ISA’s angle nut (AN) with its1/6 Turn-and-Tighten locking solution) in concert with the ANS strut cannot be rotated out of position once locked. This is accomplished with its specially tapered surface that is pulled into the T-slot Channel of the strut once a bolt is tightened to the nut. The nut can only be rotated if the bolt is loosened more than one revolution. This ensures secure connections throughout the array.
AN - 5/16 Nut Module Clamping System
The C-Clips and Waffle Clips have been developed to assure positive module clamping and single installer installation on a tilted array. Both Clips have been designed so that asymmetrical loading is applied to better hold the modules in place. The C-Clips have been designed so that they will ‘lean in’ against the module, to ensure a positive connection that cannot easily slip away in comparison with standard L shaped clamps.
The Waffle Clips have been developed with asymmetrical loading as well. This allows the installer to insert one edge of the module under one side of the clamp so that it can be initially clamped in place while the opposite side of the Clip remains open for the adjacent module insertion. Once clamped, it will stay in position, even on a tilted surface, so that the installer is free to bring over the adjacent module and insert it under the opposite side of the clip, which still has clearance.
