NOVELTY - The structure has a bi-directional panel support portion which is provided with lower support joist (20) and upper panel rail (30). The bolt head slot is provided in the sidewall of the upper panel rail. The L-shaped bracket of support portion is slidably connected to the bolt head slots. The external panels are supported from beneath and secured by the L-shaped brackets.    USE - Support structure for supporting solar panels, installed in roof and carport of building.    ADVANTAGE - The dual purpose comprehensive panel mounting system can facilitate rapid, secure installation, and deployment of the panel support structure. The panels can be easily placed on the support structure. The panel array can serve as a roof. The damage of the panels during installation process can be simplified. The support system can be easily installed on-site while resulting in a precise configuration for purposes of mounting the solar panels. The solar panel support system can be assembled very quickly on site, with little risk to installers or equipment. The solar panel support system can achieve close tolerances during field installation without the necessity of skilled labor at installation. The solar panel support system in which specialized mounting-brackets bonded to the solar panels are not necessary for the mounting of the solar panels to the support system, can be achieved. The solar panel support system can be easily adapted to a wide variety of solar panel array sizes and shapes. The solar panel support system can minimize the necessity for precise measurements at the installation site. The solar panel support system can be precisely configured to a specific environment. The degradation of support system caused by metal-to-metal contact is reduced. The support system for panel-like structures in which accommodation is made for movement caused by changes in temperatures, humidity or other environmental considerations, can be provided. A flexible arrangement for using a solar panel support system as a roof can be provided. The removal of panels can be performed easily. Easier installation of adjacent panels can be enabled, without interfering with previously installed panels. A collapsible panel support system can be provided. The deployment of the system by rotating support portions can be precisely adjusted. The support system can easily be attached to support brackets without incurring damage to any of the components of the support system. The relative rotation of structural components to deploy the support system is carefully calibrated and controlled without adjusting or tightening at the installation site. The support system can be easily fixed to a fixed mounting system using bolts, without causing damage to structural components of the support system. The panel support system can be easily deployed or removed by rotating intersecting structural components, without fouling or jamming the rotation devices. The panel support system can accommodate flexing, sagging and other deformation of the panels while maintaining a secure connection. The panel mounting system can facilitate easy electrical connections between the panels. The panel mounting system can facilitate protection of the electrical wires running from panel. The system can maintain a secure hold on the panels or panel-like structures. The support rails can ensure a secure panel connection. The panel support rail can facilitate the protection of long cable runs. The wire holders can be placed in wide range of locations on a panel support rail so as to facilitate both temporary and permanent placement of the wires. The system avoids wasting real estate by optimizing the panel array and support structure to maximize power output.The need to manipulate the panels above the support structure can be eliminated. The use of panel clips, panel holders can be eliminated, so that the process of securing the panels to the panel support structure is accelerated.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for method for mounting panels on bidirectional panel support array.    DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of the panel support system.
