Large Solar Panels - Availability

[resybaby]

I have big panels on part of my roof.
JA solar 545w things (a bit like these but a little less power)

2278 x 1134 i think they are. They look and work great but have to have the clamps fitted on the long side only, i suppose they flex too much if bolted on the other way around. If id thought more about it id have had three rails installed for certainty, although the specs say two are enough.

One thing to watch is the wind when installing them! They are like holding onto a 30kg sail, and lifting them onto the roof wasnt too much fun.

My old small panels specifically say the same and the installer didn't do it like that. They came and redid them, left my roof full of holes. The Interest free loan company replaced the roof sheets but then the new different installer refitted the panels with clips on the short side despite me telling him why this was all happening. He also said the roof sheet fixings were too short- he was going to fix them through the peaks of the sheet. Absolute disaster and in the end the finance company then gave me money for me to sort it all out myself.

City electrical have Risen Titan 550w for just under £72 each, I am probably looking to buy 20 and they have 180 in stock at the moment. You need an account which I have and they did query about mcs registration but I know the manager so shouldn't be an issue.

where do you guys get your rails and clamps from, the panel supplier or elsewhere?

Last time I bought there was a real scarcity of rails but i sourced at trade sparky. Where in the country are you Ken? Worth looking for a local contact to source from and save shipping. City plumbing would be worth a look too and well as ITS.

I'm just waiting for the price and details for the panels with rails from CEF, hopefully today sometime

Are we seeing a significant shortage of large Watt panels now? I’m in the same boat here.

i dont really want to mix and match if i can avoid it but struggling to get 575’s with any degree of consistency.

I cant afford to buy 6 panels and keep them in the garage for a couple months until my ground mounts have been agreed. Or hold out and hope it all pans out?

I was hoping wed see a drop in price but seems solar is flavour of the month again.

I got mine from city plumbing at the same time as the panels - so free shipping

Just bit the bullet and got a couple from bimble. This at least brings the partially shaded panels up to perc, half cut spec.

Maybe i’ll grab 4 more cheapy 435’s for the ground stuff as there is no shading there, and they perform very well in direct sunlight. I’ll just keep an eye on stock levels for both types.

I am interested in these 72 cell panels as they will make a neater fit on the roof I think. I am looking at the AIKO 620W 23.5% efficiency N-Type ABC.

Anything I should be aware of in the experience of those who have used them (apart from weight and wind on installation).
