www.solarpanelsinformation.co.uk While different photovoltaic systems operate on the same principles, they have different configurations. There are two basic types: one is connected to an existing power grid and the other is an independent, stand-alone system. On The Grid Photovoltaic systems that are connected to an existing grid are designed to supplement traditional gas, coal and oil-fired power plants. This requires a converter, since a photovoltaic panel produces direct current, and the US power grid runs on alternating current. In case you aren't sure of the difference, direct current, or DC, is electric energy that flows in one direction only. A common example is the household battery - which is why battery-operated devices such as CD players, small electric keyboards and some hand-held games require a special adapter (technically known as a rectifier) when plugged into the wall. Alternating current, or AC on the other hand, changes direction. This is the kind of power that comes out of your wall socket and powers most of your plug-in appliances. When it comes to integrating CPV solar power systems into a commercial grid, an inverter, or power conditioning unit (PCU) is required to turn DC into AC. This device also governs the flow of power from the photovoltaic array to the grid and vice-versa. So, for example, when power demand is low, the PCU can cut back or shut off the flow of power from the CPV solar array and open it up when demand rises. By the way, that ...
