I’m new to the solar game. I’m using will’s plans and parts recommended for a 24 system, I’m using the larger inverter and can expand to another 40a mppt if needed.

I bought 3 hqst 190w panels. Can I wire all three in series for this system. I can’t put 4 of this size on my roof.

I also have 2 renogy 100w panels

I could fit 2 of the 195w and 2 of the 100w on the roof if I can’t wire the 3 large ones together. Can I mix these panels somehow If I can’t run the 3 larger ones in series?

here are photos of what I’m working with.

The limitation may be the maximum input volts of the solar charge controller. What are the specs for it.
Here is the controller

Four of the HQST panels wired in series will have a voltage just under 100. The solar charge controller has a max voltage of 150. So you're plenty safe there.

Here is a good write-up on how to read solar panel specifications.
