CORROSION IN SOLAR PV GROUNDING AND BONDING.

Corrosion in outdoor environments is a topic that is gaining attention in the solar photovoltaic (PV) industry. Simple oxidation, galvanic, and crevice corrosion are mechanisms by which metals deteriorate when exposed to the elements. The rate and extent of corrosion depends on several factors, including environmental conditions such as moisture, temperature and pH. Galvanic action is also a common accelerator of corrosion, caused by dissimilar metals in contact with each other in the presence of an electrolyte (such as salt water). The impact of corrosion depends on the item being attacked - a large steel beam, or a small electrical connection. With regards to solar PV grounding and bonding, small electrical connections are the targets of corrosion, and the impact of such failed connections could be extensive. [ABSTRACT FROM AUTHOR]
