Over-sizing the cross section of a cable beyond the result of voltage and current theoretical calculations is, in most of cases, a worthwhile investment that is easily amortised by the electricity bill savings (reduction of Joule losses). In the case of a photovoltaic (PV) installation, the allocated price for energy (feed-in tariff) is much higher than the market price, getting amortised much faster.
Together with an improved profitability of the project, there are additional advantages when using bigger cable sections:

Various energy sources generate electrical energy in a form that cannot simply be injected into the electricity network, including photovoltaic panels, microturbines, batteries and fuel cells. These sources generate either DC voltage or AC voltage with variable frequency and/or an amplitude or voltage not compliant with the electricity network. To connect such sources to the electricity network nevertheless, a power electronic inverter or transformer must be used.

Commercial, or in other words non-technical losses account for more than 1% of electricity use around the world. The dominant component of these losses is electricity theft. In the largest extent, electricity theft is a problem related to residential customers. In some countries, electricity theft is in the range of, or far exceeding, technical losses in the transmission and distribution sector.
