yes its up and running , 29v on a 30a ivt mppt regulator and i run a 60w 12v on non mppt for comparrison...
5w from the 12v panel and i see 35w from the 29v panel in winter sun..
my 12 v panel gives 42w in summer so i expect the 29v to perform very well ...
doing it again i would use a higher voltage panel (<48v>but got 225w for £200) and select a different mppt that didnt switch off and on to protect the battery as the diodes in the panel do that...if possible.
Out of interest, and to be able to compare, how many Watts is the 29V panel?
225 w , but it only gets winter sun 2 hours a day where its parked...
Unfortunately the ivt regulator limits things further and i noticed a much better more modern regulator that has up to date super capacitor technology that would improve things quite a lot....

And the super duper new regulator is called what????????????
I would be interested in the details too.

Unfortunately the expensive ones in your second link are illustrated supporting a 4 cell panel and will in no way carry a 36 cell 80 watt or anything else useful. The mounting frame is only 300mm long also.
It was that picture however that spurred me to knock up these 24" friction hinges with 550mm frames for less that half that price
My mate has some same as these from a different supplier which are bigger and he has them on a 135 Watt Panel, Just used it as a Demo.

I put up a link somewhere, but made contact with the company via some solar panels they had for sale at the time ( their own technology mppt) it ll take time to find it..
If it is possible to get a really good, intelligent controller, then it might be possible to use a vertical axis wind turbine. It could be compact, no tower needed and much more efficient than the standard blade type.

yep, good point ... i ve measured the output of the pannel before the regulator switches it on to the battery to charge and it adds up to more than the output Ah during these winter days...
just an inefficient waste...
Not sure about the 12v panel and regulator , but it seems to me you might as well have a "winter" by pass the regulator manual switch to avoid losses in it and on an 80w panel you ll never see over 20w in winter which is perfectly fine unregulated...
been testing outputs of my new 80w and have discovered it can give 50w faced directly into winter sun but it needs a much steeper incline than your picture shows as the sun is so low....
Discovering they do "fire escape hinges" that give the much steeper angle thats needed i ve had to nab your idea and will make a set up for the panel on the back of the van like you...thanks
With the cold weather and damp, i ve gone for "sticks like sh.t" rather than sikaflex as its well within its "curing range" and you dont need the 3mm thickness application...(£4.48 a tube local)
The bond is very strong and the only difference i can see is it doesnt cure quite a "hard" as sikaflex,... but it sure "sticks like sh.t"
( i ve also sorced aluminium angle at £10 for 2.8 m local and fire escape hinges for £5.50 a pair....)
