A solar panel mounting system forming an opening for holding solar panels therein for easy installation and removal and replacement. The system includes a plurality of support members adapted for positioning on a support surface. A roof panel is positioned on a top surface of adjacent support members and compressibly held in place by an astragal which is fastened to the support member sandwiching the roof panel between the astragal and the support member. A solar panel opening is formed between projecting portions on opposing sides of the roof panel which extend at an angle substantially perpendicular to a top surface of the support member.
