Re: [AFMUG] Solar and shade for AE Fiber Cabinet

I think he's saying that if you don't have shade, then the white paint is a winner.

Huh, we have one site with a large tree shading it and it seems to do a lot better.

 

Are you saying it is not worth it to completely shade the cabinet vs. just painting it Sat White?

20+ years ago, I set up 4 identical outdoor enclosures.  Temp telemetry.  Some live load, don’t remember the details.  They were about 24” cubes.  All started out as gray.  Tried sun shields, exterior insulation, vents, fans, peltier cooling modules.  Silver paint, white paint.  The overwhelming #1 thing that lowered temps was the satellite white paint.  By a long stretch.  Then filtered powered vents.  Silver paint was worse than gray.  I wonder if the railroad still used silver.  Sun shades did little to help if the box was satellite white.  Interior styrofoam insulation helped a bit, not much, but was cheap and easy to add to the white paint.

Super hot out here in Utah.

 

My fiber cabinets running Active switches are getting harder to maintain and AC units on the side of the cabinets are starting to fail faster.

 

I’ve had the thought of shading them with a permanent four post structure and a reflective white painted cover to shade them from the southern sun exposure.

 

Then I thought, well, maybe it might be interesting to “shade” the cabinet with solar panels as well.

 

Is anyone doing this?

 

The AE cabinets all have Alpha FXM 15 or 20A units running the UPS to a string of four 12v AGM batteries.

 

I do have limited rack space in some of these available since the batteries sit in a slide out section below.

 

Haven’t done solar in like a decade since I had remote WISP type sites.

 

Is this doable to offset power costs and also get the temp down for the cabinet?

 

Or is it just a huge time suck and money pit for no real return?
