2x 100w vs 1x 200w

[vanwagon]

I'm working on my solar setup for a vanagon and need solar panel guidance.

Current equipment:
Renogy DCDC 50 amp solar and alternator charging
100ah LiFePO4 battery
Renogy Shunt


Since using the renogy SCC I am limited to 12v solar panels.
Depending on how I lay them out, I could one of these options:

2x 150w panels (300w)

2x 100w panels (200w)

Mega 100 Watt Solar Panel

The Mega 100 Watt Solar Panel features a 12V off-grid solar panel with 0~+5W guaranteed positive power output. It is an IP 65 or IP 67 rated built with strong tempered glass and aluminum frame. Certified to withstand challenging environmental conditions.

1x 200w panels (200w)

300 watts would leave little room for any other roof mounted items, so I am leaning towards one of the 200 watt options above. A single 200 watt panel is the most efficient use of space and cheapest for mounting /wiring but the specs are pretty close to what the renogy DCDC 50a charge controller will handle. Will it work?

Will it work?

Below about 18°C, that panels might exceed the 25V limit on the MPPT.

Yeah. That's what I though you would say. Case closed. Going with the 100s. Thanks
