solar PV+ thermal

[billi]

Hi
My intention today is to start an Idea

I got 20 x 50 watt panels from the sale of the last host , shipped from somewhere to the UK -to me in Ireland and now brought to Germany ....

I would like to clad nearly all of my South facing Facade with PV and an air-conditioning idea

Now i figure out ,that no cables are inserted in those panels that i have about 8 m2 to box and use the heat behind to blow into my house

What cable do you think fits in there `? I first of all want to install those as a thermal collector to my facade , blowing warm air and dehumidify the old house but need the wiring right for el production too

Is that going to be a Trombe wall? https://en.wikipedia.org/wiki/Trombe_wall
My old "Technological Self-sufficency" book talks about them, I think that they suggested having internal (to the house) and external vents top and bottom so that when it warmed up in summer it could be used to draw air out of the house, as well as the obvious circulation and warming of internal air in the winter.
Having the skin made of pv seems a good idea.

Yeah , something like the trombe Wall idea , good that all that explorer times helps now , practically

Well... Like Always , IT Takes longer , have to Wire each Panel , and forgott to bring a level Home , so Not much achieved today ,beside chating to the neighbours ....

Have Not even decided how to Wire , guess will BE 2 in pair to give me enough Voltage for a 48 V Batt Idea
