You are slipping towards the inevitable conclusion, so Iwould start planning for it matey! ..starting with reassuring wife that the panels will be higher than normal to allow reflectivity & allow transmission to catch rays on the rebound.
Get a stick & plan the potential height of a bottom panel edge with a big piece of cardboard attached to visualise headroom & start eyeing up nice chandelry materials to make it more a living architectural feature as it would be stared at from loungers alot right?
After the quake how has structural material escalated in price? ..I anticipate thats going to be a big cost factor, & how do you envisage clamping uprights for your sun pergola? ..via a drilled boot per corner & additional belt & braces wall ties?
Before you go public to get the mrs consent, draw it out & show her some nice fittings if you come across some after doing a recce at a chandlery, treat it as if a boat deck design maybe to get your head round the boots you'd likely have to drill down, seal when fitting & soft cover to avoid bare toe gashes & ensure water proofing integrity (..paul f where are you) !? ..of course planning time is to your advantage in a long term possibilities scenario.
How does the turkish wind & rain come through the area & how would that affect sola-per-gola run off potentially?
I'm guessing due to space constraints posh thin metal uprights are the order of the day to minimise floor shadow & maximise solar bounceback gains, rather than much thicker wooden supports & the shadow they'd cast? but you'd also want to avoid burnt arms & fingers potential, soumds like you ought do a few bar recce's for info on whose got solar savvy out your way who knows the local market / local solar facebook group as to what meccano kit is within reach for future assessment & backgrou d detail as to the local grid out there.
