I don't believe the cells will gain as much solar heat as something flat black.
The whole RE idea is a sickness.
I have well over, well lets just say 'KWs' of solar here. (I sell them)
Here I pretty much just run my cell phone, lab batteries, etc from mini solar.
Can't afford real solar.
So why can I afford well over $1000, maybe over $2000 for wind?
I live in a bad place (city) for it.
And I think small is cool.
The smaller the better.
My biggest success so far is 'around' 3/4 amp at 12V.
That is 2 Grand for 8 watts. $250 a watt!
What was I thinking!
Honestly, the 8 watts cost about $8 with all brand new parts.
Except the tower, tail and stuff, that is all junk from the garage.
So there must be 1992W of parts here!
And the shop is all solar, except 8W of wind.
