Granular material storage capacity increasing device and system

A grain storage system comprising:

• a housing including;
• a first side wall and a second side wall, each of said first and second side walls engaging and extending upwardly from a ground surface;
• a roof structure being attached to and extending between said first and second side walls, said roof structure including a plurality of roof trusses, each of said roof trusses including an inner chord, said roof trusses being laterally spaced from each other;
• a plurality of panels being attached to said roof structure to define an auxiliary storage capacity above said first and second side walls supported by said roof structure, each of said panels extending between and being attached to adjacently positioned ones of said inner chords, said panels each being horizontally oriented;
• each of said panels being elongated, each of said panels having;
• a first end, a second end, an upper edge, a lower edge, an inner surface and an outer surface;
• an upper bend being positioned adjacent to said upper edge, an upper flange being defined between said upper bend and said upper edge;
• a lower bend being positioned adjacent to said lower edge, a lower flange being defined between said lower bend and said lower edge;
• and
• a primary bend being positioned between said upper and lower bends, said upper and lower flanges each being attached to said inner chord, said primary bend being spaced further from said inner chord than said first and second ends.
