Did an initial bring-up of this board. All went well. I didn't connect Benchpod's ADC/DAC to it yet, as aI was first testing with 5V input and 3.3V DAC input to see if it's working properly. The INA measurements are a tiny bit off, because the resistors R25 and R26 are connected to the copper pour instead of traces, which adds some distortion. I should've just run traces for those 2 resistors instead of positioning them on the FET's copper pour with the shunt resistor. 

All in all it works well and I'll continue testing, including with a real ADC/DAC (BenchPod's) to do a full solar cell simulation up to 48V (with 24V input).

I also realized I can use it as a battery simulator as well, just need to change the model in BenchPod from solar to battery and we should be good to go.

Here's how to finished board looks like:
