Solar Panel//Underside//Thermoelectric
I have seen this suggested idea..
This is fairly straight forward idea to take solar panel and on the underside of panel mount thermoelectric square pads. I have/ am considering doing this just for the sake of trial if nothing else.... Now which size solar panel and how many and which size thermoelectric generators....solar PV meet TEG

TEGS are inefficient under optimal conditions, and even more so by covering them with a solar panel rather than a heat sink. The bottom side would need to dissipate heat somehow if the solar side is providing the heat.

It would be interesting to see if this actually produces more energy or less. The TEGs will insulate the back of the panel to some degree which will reduce the solar cell efficiency.

It would have to be a thermal solar to even begin to make sense even then PV is more efficient cost wise.
The only benefit a teg would have over solar is it could work anytime you needed it like the middle of the night, powering it with say a coal or wood fire.

I'd like to put a 3-4x24-32ft collector for heating air on the roof of my 35ft trailer. Partially for the roof insulation, as well as space heating.
When I heard Tesla rents solar installs for $50/ month, I thought — replace the black body and glazing with PV panels.

I wouldn't waste my time with a tesla rental system.

I doubt it would ever happen, but it made me have the thought. About a single row of panels connected end-to-end.
It wouldn't save money, my bill runs $40-80/month.

A roof top rig made with used poly panels and used inverter could run you 70 cents a watt if you do it your self.

Since polycarbonate passed 90+% of light, might it make sense to glaze over the panels and pass air above and/or below them?
I'm not cutting holes in the roof, but if I was building from scratch it'd be a trolley-top, with curved solar panels on top with 23-window bus roof lights using Dodge Caravan frameless hinges and latches. The ribs would be aluminum I-channel with dimple-died lightening holes.

Tempered glass, polycrystalline cells.
Are you talking about vehicle installls?
