Solar Panels Monocrystalin verses Polycrystalin

One could answer that with 'what make is better suited to 4x4, Toyota or Nissan'.
LOL
Seriously, I do not think there is a 'best suited' answer to your solar panel question - I use an amorphous panel mainly due their shade tolerance.

perhaps reading up a bit on panel technology (google) would save a few one finger typists here getting sore fingers.

As I understand it, Monocrystalline have laboratory performance of 23%, Polycrystalline has 18% efficiency and Amorphous has 12% - lab results are however, not out back results Most panels these days seem to be Mono

I have a 140 watt mono mounted flat on my Jeeps roofrack - It powers a Waeco cf50 through a 100 aH AGM and MPPT solar regulator .. Never had a problem yet .

Poly panels have a slightly larger frame size and area compared to mono but they are both susceptible to any amount of shade ..
