[RE-wrenches] Installation Environment, Mold

[Windsun@wind-sun.com]

Around most treatment plants, moisture is not the main problem, it is the 
H2S that is constantly present. At night when it cools off, you can get 
condensation which picks that up from the atmosphere and makes a weak acid. 
That can cause corrosion of metal parts much faster than normal.

> Wrenches,

> Hope your days are going well.  We have a prospective customer (adjacent

> mold growth on or under the PVL laminate modules that we are planning to
> install. The PVL module datasheet states that the adhesive has a microbial
> inhibitor but the customer does not believe that inhibitor alone will
> prevent mold from growing on, under or around the modules.  The customer
> also suggests that the environment will be more acidic than typical.  They
> have inquired as to how the pv equipment may be affected by these items 
> over
