Instead of guessing, let's look at what's needed.
The panel under discussion is 195W, Imp = 5.38A, Vmp = 36.2V. Three panels in parallel
Sorry. I was thinking 4*12V, namely 4*150 or 4*160 in parallel, since the OP main objective appeared to be the low cost and those were the cheapest.

The OP wants to buy the cheapest panels on earth, yet you want him to purchase a $60 combiner box??? When a substitute box can be gotten for under $5?
No. I "don't want" them to purchase $$ combiner box, but they "will have to", if they go for PWM and parallel wiring :)... And the substitute is not $5, but $5 +terminals + some elbow grease to put it together. And $5 is a PVC from Home Depot that doesn't look like up to prolonged UV and heat exposure.
