Generally, most of people will pay attention to the cleaning of solar panel and ignore the cleaning of the inside of rail. No matter where the solar panels are installed, ground or roof, there must be water flowing into the rail or small bugs settling here, whichmust accelerate the corrosion of the inside of rail and shorten the service life of rail.
Now, we have a product that can protect the rail from the entering of rain and small bugs, that is PE end cap for solar panel rail. And PE is an recyclable material which cannot pollute environment. Currently, we have two kind of end caps, black and gray, with different internal structure. its size is 40*40mm that fits rail with arc angle.
SIC has been focusing on solar system for many years, quality assurance, welcome to come to consult.
