installing a 12 kWp system on an essentially flat roof. 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.</span></font></p>

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?
