You can't do anything about the temperature, but you can fix your wiring and connections. I would like a way to know, when I am getting fewer amps than I would like, whether it is just the temp doing that to me or if I should be checking for bad connections.
That is important with portable set-ups where you do a lot of connection and wiring changes, but may not be a concern with a permanent installation.
So what are the specified expected amps with 24v panels and MPPT? I was asking about that in another thread.
With 12v and PWM it is panel Isc, but it doesn't work that way with 24v and MPPT. Using the OP data here it seems you could get an idea what to expect for your latitude, time of year(date), and temp
