Adding Solar to existing setup

[Solidox]

Currently I have a setup not installed yet that has 2x 100w solar panels going into a MPPT to the battery. I want to add either 2x 50w or maybe a 200w to the system but the specs of these dont match the 100w panel. Would it be worth it to buy a separate MPPT/PWM or just tie it all together and suckup the loss in efficiency?

My advice for the money would get 2 more 100w panels if you want 200 more watts if your mppt can handle it.  If you want 200w panel,  get another mppt. Wasting 100w does not seem right.

My only issue is space, this is going ontop of a chevy g20 with two roof fans. The MPPT could easily handle it as I bought one for overkill incase of upgrade down the line.

There  are ways.

Thanks for that, I'll have to take a few more measurements to see if two 100 could fit. If not and only a 200 would I could always just get a pwm for only that panel.

My folding panels came with a pwm. I upgraded to a mppt. You could really see the productivity in production.
