PTP, What is TSP ( ) wash and rinse? Sounds like YAYOQ (you answered your own questions). We have a CC (common circumstance). I'm hoping TSP is some sort of not-totally-toxic chemical bath that will eat away the anodization quickly and efficiently, and simply wash off into ??. Are you anticipating dunking the legs, rails into a tub or tray? Also, do you hope to get a similar "anodized" black look to your painted legs/rails and really want to match the BP modules or does it just have to be black with a similar gloss/shine? I would ask the client to pony up for powder-coated process/finish for the various leg/rail/hardware pieces. What about the back of the modules, aren't they white? Is the client aware of this? Or will the actual backsides of the modules not be visible at all? If so, what's the color of the walls and/or parapet exterior? Should modules frames or backsides be painted or coated at all? An alternative might be to find a truck bed DIY (do it yourself) spray product. I don't think you would have to worry about the anodization with this coating product. Be sure to protect the holes and threads. Thanks, PSD

The terrain slopes down from the street to the house (and there is an additional 2.5 deg slope on the roof in the same direction), hence making the array visible at some point away from the house going towards the street. The client has asked us to paint the back tilt-legs and rails of the array the same color as the PV module frames. The reason being the legs and rails are clear anodized (ProSolar) and the modules are black anodized (BP SX3200). We are talking about only the back of one row, as the front of the row is so low as to be truly out of sight. The question: what do we need to do to prep and paint the clear anodized tilt legs and rails? I'm hoping that a quick TSP wash and rinse, followed by a primer appropriate for Al, followed by a high quality exterior paint. Any suggestions on primer and finish coat products? We want this to look good and last a long time. Thanks, - Peter Peter T.

The lack of an accurate metering system is one of the biggest elephants in the room with this inverter/CC system. Todd Allan Sindelar wrote: No virus found in this incoming message.
