Wiley Electronics is the creator of the well known bonding washers WEEB. WEEB stands for "washer, electrical equipment bonding". WEEB products are used to bond solar modules to aluminum racking and mounting rails. The solar modules and the racking system are then grounded, grounding and interconnecting the entire assembly into one single grounding system. The use of WEEBs eliminates the need to use a lay-in lug and/or a thread-forming screw on each module. The use of WEEBs also eliminates the need to run a continuous wire to each module. Wire is only needed to connect a lay-in lug on each mounting rail to an equipment grounding terminal in the inverter or disconnect.
