Rail

Flashing

I really didn’t spend much time on this aspect, yet when you think of it, from a structural point of view, it is the most important. You may have the best inverter and the most efficient modules but if the hardware is poorly installed or not of sufficient quality, it will not only fail prematurely but may create a safety hazard.






There are a few points that I did catch:

• should be made of aluminum or stainless steel

• bolts should be tightened to specifications

• always use flashing to prevent leaks

• make sure that the WEEB grounding clips are the “outdoor” version not the indoor version. They look similar and can be confused even by pros. This is important because of deterioration over the long period of time the hardware will be exposed to the weather.
