FAQ (Frequently Asked Questions)
What material is best for a grounding cable ?
Copper is the preferred material for grounding cables due to its high conductivity, thus ensuring efficient transmission of electricity and better security. Aluminum can be used as a more economical alternative, but it is slightly less conductive than copper.
Can we use standard cable for solar panels ?
Non, standard cables are not suitable for solar panels. It is important to use cables specifically designed for photovoltaic systems, as PV cables, which are resistant to external conditions, such as UV rays, humidity and extreme temperatures.
What is the average lifespan of a cable? ?
The lifespan of a cable depends on several factors, but in general, a quality cable can last between 20 et 50 ans. However, the installation environment, such as climatic conditions and humidity, can influence this lifespan. Cables exposed to harsh conditions require adequate maintenance to ensure their longevity.
