Well, I'm
"shattered" at me self. Learn from my own dumbf**kery here folks.
When it rains, the solar panel on my roof has always pooled water on whatever corner the car slopes towards. The alloy surround is slightly higher than the "glass" portion, hence the water cannot run off freely.
Thought I'd attempt rectifying this, by drilling some 1-2mm holes to act as drainage points. I drilled through the corner part of the bracket and well and truly away from the "circuit" part of the panel. But , it didn't end well did it... Alloy hole went no worries, but once the drill punctured through the glass part, it was like watching a movie scene where some poor sod's standing on ice and a web of cracks surrounds him like a spider web... The whole panel turned into a mosaic within 10 seconds. Whats worse is the panel worked flawlessly, pooled water or not, over the 2-3 years it's been up there. Don't know what got into me to fix it now...
I've thrown firewood, swags, fire grills, right on top of the panel. Been hit with a ratchet numerous times. Not even a scratch!! But a tiny hole on one extreme corner and it's game over!! I've never seen anything like it!
