Have you got samples of poor installation practice?
See Australian samples of poor solar installation practice. You do get what you pay for.
Ohhh... Solar Pergola
Poor positioning of inverter next to gas meter
Support legs installed too low on the panel - causing wind load stress on top of the panel
Array with wire shading and poor maintenance
Cabeling & inverter connection realised poorly
Corroding weathered earthing
Delaminating panel
Dangerous plug - bottom of inverter
Earthing could be better
Exposed cabling - should be in conduit
Frame corrosion and yellowing panel
If possible - avoid cable run accross gutters
More yellowing panels
Not in line with Australian Standard
Panel positioning not adding to the look
Panel with extensive micro cracks
Panels too close to edge
Poor cable run - not in line with standards
Poor installation position
Poor installation positioning causing overshadowing
Poor positionng of panels - with vent causing significant overshadowing issue
Poor system positioning
Poor work practice
Rubber solar cables after years of sun exposure
Rusted tin roof bracket -12 month after install
Scratched & marked waffers
Tree shadowing panels - causing poor output result
Twisted panel
Wafer delamination
Watch out for broken tiles - water damage will cause expensive plaster repairs
Water damage in isolator
If solar panels are transported poorly , it can lead to micro cracks
Water entered poorly positioned conduit and directed the water towards solar system cut off switch
Water damage to solar cut off switch
A bit more silicon with this instalation - poor workmanship
Poor workmanship sample - Silicon fixes everything - but only for a few month
Poor maintenance over a very long period can result in poor electricity output
Isolator Upside Down
Ugly and Incorrect Cables
Poor cabling fixed by LG authorised solar installer
End Clamp Hanging off rail
Tin Bracket horribly installed
Packers under midclamp for unknown reasons
More Endclamp Madness
Bad Quality Frame Installation
Reinstalled by LG Installer
Main Array Earth
Joiner coming apart, roofing screws used as fixings
Incorrect feet used in Gully causing numerous leaks
More roofing screws madness
Ugly work
More Ugly stuff
Loose connection causing major meltdown
Total lack of waterproofing awareness eventually causing inverter failure
Poorly installed endclamp will see failure of panel grip in the future
Poor quality isolation box and isolators
Not a long term cabling solution
Tilt frame poorly positioned causing water penetration of metal roof
Home made joint of the installation framing ,likely to fail in heavy winds
Another poorly executed framing joining has vibrated loose
