The main keys to a successful PV installation are the design of the PV system, the quality of the PV components and a correct installation. The choice of components is critical in any system. When talking about PV components, the primary focus is on modules, inverters and panel support structures. Certainly, these components are crucial in the installations and represent a major part of the investment.  However, the PV wire is undeniably a critical system component.

The PV or solar cables are part of the Balance of System (BOS) in a PV installation and represent only 1-2% of the total installation cost.  For this reason, PV cables are often overlooked but are a crucial part of any PV installation. PV wires that meet the industry standards, are good quality and are sized properly provide safety and longer-lasting systems.

Solar cables are often exposed to harsh environmental conditions: UV radiation, moisture, temperature fluctuations as well as wind, snow and rain.  Inadequate cables are one of the first components of the system to show failures by interrupting energy generation.  The loses in generation and revenue, coupled with high replacement costs, demand that the right product is selected for the job at hand.  Every kW lost in generation due to poor quality cables is a loss in terms of return on investment.

PV wire failures disrupt power generation which leads to replacement of the cables and replacement costs.  In addition to the costs of the repair, there is a risk of damaging panels or other components. The initial investment in good quality PV cables becomes immaterial compared to the potential risk stemming from the use of low performance cables.
