Well I've made my choice and went for framed panels, but only after buying some flexible ones and being disappointed in the quality.
Build plans:
1* 25ft 6awg cable with anderson sb50's on either end
1* Renogy commander 40amp + meter (again sb50 on pv side)
4* Renogy eclipse 100w 40"x20" mono panels (bargain at $1.30 per watt!)
1* sb50 - 4* mc4 break out cable (I may add a pair of powerpole disconnects between each mc4 and the sb50 to make it even easier to move around)
Just waiting for the panels to arrive on Tuesday, excited
