An example of solar cabling or wiring works “done right” is by having experienced solar engineers design a solar PV system with all the right components from solar panels to proper recommended solar cabling. This leaves out any doubts on what components to select and sets the proper framework before any installation work begins.
At this stage the right solar cables and wiring is chosen to handle the right amp the solar cable or wiring would be required to handle. This leaves out the risk of a cable overheating under heavy loads.
To handle the harsh weather conditions, armored or heavy-duty insulated cables are recommended since some solar cables or wiring would be exposed to extended hours under the sun.
Distance between solar PV components play a role too in ensuring optimized power generation as electricity will suffer losses if the cables are too long.
Cable and wire trunking or insulations are neatly installed and aesthetically pleasing. Messy cables and wires, or worse, poorly terminated cables are signs of poor cable and wiring management. These should be avoided at all costs!
Lastly, any respectable solar energy company would offer workmanship warranties for any installation works performed by their installers.
