Installing Landscape panels without any gaps between rows

[powervan]

after your last slate advise i bought 24 of them but fitters said to much hassle and leaded it!! its only money

Short side fitting, couple of reasons for not doing it, most wont allow it as in Europe (read Southern Germany) panels are expected to withstand 5400 pascals of load pressure (equates to about 6ft of snow load) REC will allow short side but it reduces load capability on their panel to 2800 pascals. The load is borne by the frame so a deeper frame with thicker material usually means they will allow it but not always. Most UK sites are unlikely to need 5400 pascals so its not too much of an issue, whats more of an issue is microcracking when the panels are supported at the ends the panel flexes across its length causing microcracking in the cells, it therefore increases recombination losses in the cells which means higher degradation rates for the manufacturers to contend with on their warranties also it lowers your customers yields so not a good idea!

We're all learning - all the time that's what I like about the Forum. A bit of support when you've had a bad day (or fortnight at the minute!) food for thought about things you thought you knew and completely new trains of thought. That's what makes it interesting.

So dragging up this old post,

Hyundai can be clamped on the short side and mounted landscape on a standard Schuco rail system?

Found my own answer, they will not allow it!!

which hyundai panels?

I'm certain they will allow it on the hyundai panels we use (250 or 218 Wp mono, black framed Hyundais)

yep - anywhere within 1/4 of the length of the short side, so effectively anywhere within about 24cm of the edge. Only up to 2400 Pa loading though, so not suitable for the worst wind and snow loading situations.

Strange, must be an old installation manual I googled!!!!

YOU HAVE MADE MY EVENING!!!!!!!!

Thankyou!

no worries, you had me worried for a second there as I knew we'd mounted on the short side a few times on the Hyundais, it's one of the reasons we like them so much.
