Due to the multitude of wire management products on the market, the experience of choosing a wire management solution can lead to confusion and frustration. Wire management can be one of the most challenging aspects of PV system installations. This quick reference guide is designed to ease the decision making process and guide the user to the most suitable wire management choices for the full line of DPW Solar PV racking systems.

Within this guide is information on a variety of wire management solutions/products that have been carefully selected. Each has been evaluated, tested, and approved by DPW Solar. The wire management products represented include both DPW Solar and third party solutions.

Know the PV Module Rail in Use

DPW Solar manufactures seven types of module rails, or rail profiles. The rail type will vary from system to system and is determined by several factors e.g., site location, size of array, module size, weather factors, soil conditions etc. If you do not know the rail in use for a specific site, contact DPW Solar for assistance. Knowing the rail type is key in utilizing this guide.

The table below defines the commonly used PV module rails on the full range of DPW Solar racking systems. On the following page there are two diagrams showing each of the seven rail profiles. The first diagram “DPW Solar Rail Types” provides basic rail dimensions, the second diagram “Wire Fill Capacity” provides theoretical wire fill capacities within each of the rail channels.

The remaining pages are organized by PV module rail type, showing the various wire management solutions for each of the seven rail types. There are also website addresses/hyperlinks for each of the wire management products.

WARNING:

Without exception, wire fill capacities shown are theoretical. Site specific real world conditions must be applied and calculated when determining wire fill capacities. Failure to do so could lead to heat build up, system failure and severe personal injury or death. Furthermore, failure to perform site specific calculations and apply those calculations voids the system warranty.
