Hi :)
I was at the tipshop for Nelson Bay area at the weekend and they had a stack of 29 solar panels for sale. Looked in VGC and not too old or damaged. Trina 250W for $50 each. The guy said they started with several hundred and they were the last left. :o

Seemed a good price to me if you want one or several for a camping project or off grid setup. Bulk discount available. Someone bought 150 of them ! :roll:

Trina 250PC05A. Note 30cell type. 250W, MPV- 30.5V, MPC- 8.20A.
Also some new electrical meter boxes.

You will most likely find they have leaking to earth faults. Fine on 12, 24 or 48V systems. Just don't string lots together.

could you be a bit more specific? i mean you throw in a new idea, but you try not to tell us how and what and why?

Classic! :D

Can't wait for the next instalment.

Not quite "Who's on First", but not bad.

Hey Lantern, your name isn't Tim by any chance?

No. Not a Tim.
But I do wonder, if he doesn't know how to check for this should he even be trying?
I do not want to be responsible for him flying off the roof.
