Kind of new to solar power. Need help with a connection.

Currently I have a renogy 100w monocrystalline panel with a 20amp controller connected to a 2000w energizer inverter and a 12v 100ah renogy marine gel battery, see links below.

I just purchased another renogy panel that is the same as the one I have. I want to know the best way to connect this either parallel or series because I am so confused. This is going to be powering 3 fans a tiny space heater and 4 small water pumps for my hydroponic greenhouse (these will be on a timer and will go on and off periodically, they will not all be on at the same time)

Thanks for the help!

If your CC is a PWM, hook them in parallel. If your CC is an MPPT you can do series or parallel. If shading of one panel may be a problem, do parallel. If no shading issues I'd put them in series.

Thanks for the speedy reply, I'm going to be doing this now. It is PWM btw. Thanks again!
