An experienced electrician would be able to install solar conduit easily. They would take care that they are fixed correctly. If a professional is installing the PV system without using conduit, then it is time for the owner to fire the person and hire a better and experienced professional in this regard.

While installing a conduit, the wire is pulled through the tubing and typically passed through walls, under driveways, secured to the exterior and even to the interior of a house. Conduit installation protects the wires in residential and commercial buildings as well.

The conduit can be defined as hard, durable protective tubing that completely covers the wires so that they are protected from external elements like water and sun. A solar power system without a conduit would mean the wire getting wet that could lead to corrosion and cause the PV system to suffer extensive damage that would need expensive repairs. Wires without conduit would heat up and in few cases start a fire, leading to an accident.

Manufacturers provide the owners with a wide range of conduits. The most commonly used designs are:

• Metallic tubing: It is similar to rigid steel conduit but walls are less thicker. It is easier to shape but not tough.
It is available in a flexible version also.

• Non-metallic tubing: Rugged plastic is used in making of PVC conduits. This conduit is cheaper but strong and waterproof with a very low absorption rate.

• Rigid steel conduit: This is the strongest type of tubing and resembles a thick metal pipe that is threaded on both sides. Its strength and durability make it one of the best choices. It is very difficult to cut or bend this conduit.

It is important for the professional to follow few rules while installing the system. This is mainly to increase the safety of people living and using it. Small steps would be of great help.
