Recommendations for solar charge/controller
It appears a buddy of mind is going to donate two used 300 watt panels. They are rated at 30 volts with about 8 amps open voltage (he got them for a song - used I should say) We’ve been out in t...

I got the info - regarding the panels, because I've always been told design is based on reality, not vaporware (software design I should say)....
Brand: AstronEnergy
Model: CHSM6612p-305
Open Circuit Voltage (VOC): 45.29v
Short Circuit Current (ISC) 8.95A
Voltage at PMax (Vmp): 35.77v
Current at PMax (Imp): 8.95A
It's a poly cell
Since I'm going to mount them on the roof (obviously) and there is some shading possible depending on orientation due to vents and AC, do I want wire them in series upping the voltage or parallel?
Also, I remember reading a very lengthy discussion regarding some important stuff about wiring in parallel vs series - and whether the panels have diodes in them so the shaded panel doesn't detract from the panel in full sun?
I'm not planning on mounting the panels at an angle. I'm just hoping my friend Bernoulli doesn't decide to make a wing out of the panels (maybe the solution would be to put something in front of the panel to create vortices to disturb the airflow over the panels and prevent laminar flow - disrupting the lift from the natural cord shape.
