How Deep Do Solar Cables Need to Be Buried?
A frequent question is how deep solar cables need to be buried. Where PV, low voltage or medium voltage power cables are installed underground, the burial depth is determined by national wiring regulations, site conditions and mechanical protection requirements, rather than by the cable type alone.
As a general guide, underground power cables are usually installed at a depth sufficient to protect them from accidental damage, typically in the range of several hundred millimetres below finished ground level, and sometimes deeper in areas subject to vehicle traffic or future excavation.
