What is the money-saving finish for aluminum solar mounting accessories?

What is the finish of PV module frame? It is almost a universal standard that all PV modules have a anodized film of 15um thickness because PV modules could be installed in an industrial area and also possibly installed in residential area. For industrial zone the corrosion atmosphere could be much worse than residential area.?The?PV?modules?are fabricated in an?standardized,?massive?and automatic production line, so all PV modules are fabricated to meet all possible installation situation for the whole service life. ??

But to aluminum hooks and other similar fixing accessories, it will be mostly applied in residential area and pitch roofs where it has beautiful view and good air quality. There should be no worries for the corrosion atmosphere. Under these circumstances, Mill finish will already be good enough to serve the PV system of the whole project life more than 30 years. And this will be the most economical solution for residential project or home purpose.

But when you are enjoying your sunshine on your balcony or lawn, you would not be pleasant if the sun light was reflected by your neighbor’s roof PV system. This could happen by fixing clamps, hooks, and also rails since mill finish can still be shining even after installation. Mill finish will be strong enough but it will not be good enough.

Matt mill finish and black anodized finish are much better choices. Matt mill finish is another process which will make the shining surface become matt by continuously grinding the pieces in a grinding machine. This process will not increase the cost too much but it will reduce the reflectiveness marvelously.

Black anodized finish is the better solution for the residential roofs. Especially when you are applying the black PV modules for both the glass part and also the frame part. So the fixing accessories will blend with the whole system deeply.

Conclusion：

For residential solar projects, applying finish accessories and also anodized finish would be good enough for the whole project service life. But there would be some cost difference and aesthetical difference.

For industrial projects, Anodized 10um thickness would be a minimum requirement for aluminum accessories.
