[RE-wrenches] Lumos LSX250 modules

[Chris Worcester]

Hi Benn,

I purchased a set of 4 years ago through a local glass company that does a lot of custom window installs, using these on some really big expensive Tahoe Lake Front home’s fixed windows. I recommend that approach if you have a good local glass shop, for top quality suction cups. We swung groups of 4 modules into place on this 10:12.

To those who have used the suction cups to help with handling these mods, did you purchase or rent the suction cups?  

Any insights to share regarding your choices?

 

I have a 19kw vertical wall install coming up in a couple weeks.

Chris,

 

We have done a few Lumos projects down here in the Gulf South, where snow removal is not an issue. Please see attached for an example rooftop installation - these modules definitely end up looking pretty "slick".

I would echo August's comment about the rail alignment. The module mounting holes allow for a bit of wiggle room, enough to square up any off-kilter modules but not enough to make up for misaligned/non-parallel rails. I would also highly recommend the slotted rails (don't know if the non-slotted rails are even still an option).

 

As you pointed out wire management is simplified with their rails. Wires running perpendicular to the rails can be accommodated by removing one or more of the rubber bumpers to create a gap between the module and rail. We have also used suction cups to assist in lifting these modules to the roof - at 60 pounds apiece they are noticeably heavier that most of other modules we deal with.

Hi Chris,



We have a complex 86 kW commercial job with Lumos 250s we?ve just kicked
off. We have not installed them yet so I can?t offer a whole lot of advice
except that the module leads won?t reach each other in landscape
orientation so I?d recommend a standard portrait layout. The rails also
need to line up perfectly since the modules mount with the four
through-holes.



We will be landing our panels in about 3 weeks so I should know more then,
feel free to ping me if you haven?t made your decision yet.



Best,



August
