Solar Grid Connected PV System

Solar Grid Connected PV System is connected to a large public electrical grid (owned by utility company) and feeds power into the grid.

This system modify in size from residential (2-10kW) to solar power stations (1-10MW).

In the case of residential or building mounted Solar Grid Connected PV System, the electricity demand of the building is met by the PV system and only the excess is fed into the grid when there is an excess.

The consumption of PV generated electricity into the grid requires the transformation of DC into AC by a grid-controlled inverter.

On the AC side, the function of grid-connected inverter is to provide electricity in sinusoidal form, matched to the grid rate, limit feed in voltage to no higher than the grid voltage including disconnecting from the grid if the grid voltage is turned off.

On the DC side, because the power output of a module modifies as a function of the voltage that power generation can only be optimized by varying the system voltage to find the 'maximum power point'. Most inverters therefore incorporate 'maximum power point tracking'.
