Turning brown is caused by UV, weathering and environmental heat, not
heating from load, and has a relatively small effect on power output (on
the order of 5-10%). See:

If that were true, [SNIP]

It is true, as shown by my supporting citations.

Typical solar panels convert only about 20% of captured solar energy
into electricity. The other 80% is wasted as heat. Thus if even half
the power of the solar cell were converted into additional heat, it
would only increase heating by about 12% (10 ÷ 80), which isn't terribly
significant.

If you have any real evidence (citations) to the contrary, then by all
means post it.

The funny thing is, that a loaded solar array is cooler than
an unloaded one.
The unloaded one absorbs heat, the loaded one less, because you
convert to electricity, and use it.
So by loading it , you remove heat.
Not all of it, because part of the energy is lost as heat.
