Self-tapping tech screws seem to be the connection method of choice among many contractors, particularly for connecting earthing conductors to solar panel framework.
Clause 4.8 of AS/NZS 3100:2009 Approval and test specification – General requirements for electrical equipment, only permits the use of self-tapping screws for earth connections where:
a. It is not necessary to disturb the connection in normal use; and
b. at least two screws are used for each connection (don’t think we’ve ever seen that!).
Generally speaking, tech screws were never designed to be used for earth connections;
they were intended for fastening structural components. Various issues with using tech screws for earth connections include:
• Loosening of connections due to vibration and temperature variation
• Deterioration of connection when reused
• Poor electrical continuity, eg due to aluminium oxide/anodizing of solar panel framework, and
• Corrosion of connection
There are numerous earth connection devices available on the market specific for earthing solar panel framework. Ensure such devices are installed using techniques as specified by the manufacturer instructions, including sealing such connections against the effects of corrosion.

Would you trust this connection to be reliable for the life of the installation?

Were you aware that new design guidelines and the possible reclassification of PV modules will see a requirement for earthing of PV arrays?
DKSH are delighted to announce that we have sourced more world leading products to be able to cater to this new requirement.
Earth Connectors (Wiley WEEB washers & Lugs)
The process of fitting lugs to every solar panel and earthing individually could add an hour or more to every installation – a very expensive exercise. Wiley have a solution!
Using their patented WEEB washer technology, a lug is fitted to the rail, and then WEEB washers are fitted to the clamps to electrically connect each individual PV module to the rail. The WEEB washer has special “teeth” that penetrate the anodised aluminium and create a gas tight and electrical bond. Once the rail is earthed, the process of earthing each PV module takes as little as 10 seconds.

The WEEB line of products is designed to bond solar PV modules to mounting structures and create an electrical path to ground. WEEBs eliminate the need for older, more costly grounding methods and greatly reduce the amount of labor and materials used in installations.
The innovative WEEB design removes the need to run ground wire to each individual module and eliminates the need for surface preparation on anodized aluminum components.
To install, WEEBs are placed between PV modules and mounting rails at clamping points or at bolted connections. When anti-seize is applied and the hardware is tightened down to the appropriate torque spec, the WEEBs’ specialized teeth embed into anodized aluminum, galvanized steel, or any electrically conductive metal to establish a gas tight electrical connection.

for use in Canada and the USA• Maximum electrical equipment ground
conductor size when used with 2 WEEBs contacting each module in an assembly: 6 AWG

WEEB WasherWasher, Electrical Equipment Bond
What is a WEEB?The WEEB (Washer, Electrical Equipment Bond) is the first production part specifically intended for use in grounding photovoltaic systems. There is a family of WEEB parts, one for each kind of photovoltaic mounting system. The WEEBs are used to bond photovoltaic modules to the mounting structure. A ground is connected to the resulting composite structure so that the photovoltaic modules are also grounded. This is more technically described in NEC sections 250.136 and 250.134 and discussed at the company website, http://www.wellc.com/WEEB_nec.html.
How much current can WEEBs carry?All WEEBs are tested to carry a current of 1530 Amperes for 6 seconds. This is much more than any photovoltaic module can source and is why the WEEBs offer better lightning protection than previous grounding methods. All WEEBS meet ANSI/UL 467, standard for grounding and bonding equipment.
Why Should I Use it?• It saves you time! No more running ground
wire to every PV module• It’s safe... meets ANSI/UL467 requirements
for bonding/grounding systems• It’s reliable• Patented design features stainless steel
teeth that pierce into anodized aluminum, providing a gas tight connection which prevents oxidation and gives more consistent results than the method of scraping off the anodized coating by hand and using star washers.
The products use patent pending technology for bonding anodized aluminum surfaces together. Bonding PV modules to a mounting structure removes the need to wire the modules separately: just the mounting structure needs to be wired to ground.
