In the case of Chile, PV deployment has been focused on medium- and large-scale power plants, which is the opposite
of what has occurred in other countries where distributed generation has played a significant role (i.e., Germany, Australia, and Italy). Nevertheless, as mentioned before, in 2012 the government implemented a law facilitating the supply of surplus energy to distribution networks by small generating units (less than 100 kW). In fact, this law lets regulated clients that have installed electrical generating equipment for supplying their own electricity needs, using nonconventional renewable energy or efficient combined heat and power (CHP), to feed electricity they have generated into the distribution network under a net billing scheme. Nowadays, the rules for applying this mechanism have been clarified, and there is a great deal of expectation about the results. In this context, PVs appears as the key technology to be deployed, but such expectations are to a large extent aimed at commercial users, as the mechanism does not imply subsidies and most residential users do not have the means to afford investments of this type. Finally, along with the rules, a technical standard for the connection and operation of such facilities at both the low- and medium voltage levels has been developed.
