i went to home depot bought angle Alu in the hardware isles
cut it into pieces, drilled holes in the edge frame of the panels
i can unbolt them clean under neath with out touching the roof screws
most users have done something similar, even adding lift bars to hold panel on a tilt
outside edge should be lower than inside edge
slight 2 degree tilt allows for rain run off, helps keep the panel cleaner
i did not think of that when i did mine
some day i will add a 2" extension plate on the inside edge of mine
just need to cut 20 pieces of Alu plate and drill holes
then climb on the roof, yeah 'real soon'
do it right the first time
rework is a PITA
