Solar radiation may be converted directly into solar power (electricity) by solar cells, or photovoltaic cells. In such cells, a small electric voltage is generated when light strikes the junction between a metal and a semiconductor (such as silicon) or the junction between two different semiconductors. Both solar power and are , meaning that all available output must be used locally, carried on lines to be used elsewhere, or stored (e.

Distribution substations connect to the transmission system and lower the transmission voltage to medium voltage ranging between 2 kV and 33 kV with the use of transformers. Traditionally, the distribution systems would only operate as simple distribution lines where the electricity from the would. Electricity is delivered at a frequency of either 50 or 60 Hz, depending on the region.
