I used them before on a boat. Do you have any thoughts on them? BTW, I plan to mount a 335W Panasonic panel.

That mounting set is ingtend for a completely flat surface, while the TM shells are built with significant curvature very high in the middle (compared to the street and curb edges).

If you will mount with 'longer side' of the solar panel frame front-to-back, then the linear pieces (for the the middles of those long sides) will be usable. But you will not able to use those pieces for the case of mounting with the long dimension sideways (street side to curb side.)
