Solar PV issues

[Roddie82]

Our company are having issues with solar pv panels fitted over a year ago, they are LUXOR 250W and we've had nothing but issues with them underperforming, water ingress etc yet the company who manufactures them are disputing this (obviously). Has anyone else had issues with these panels?

Its a bit of a broad opening post to give any meaningful feedback - how are they installed? shading? SAP calc? who says there under-performing? what you measuring against?

more info will help.
