Virtually maintenance free, this kind of system is used in places where secondary source of power other than grid supply is needed. Power generated

by solar is converted into AC current to power household load. Inverter balances the two sources of power so that any excess energy needed by the load is taken from the grid. On the other hand, any extra power from the solar is fed back into the grid thereby turning the energy meter backwards.

Functions of different components

Solar panels: Converts sun light into electric current.   Rated in terms of peak watts produced.  Apex stocks panels from 10Wp to 185Wp (70WHr to 1,295WHr @ 7 Hr Irradiance).  For higher requirement, multiple panels are used which are connected in combination of parallel and series connections.

Inverter: Power from the solar panel is both maximized and converted into AC using Grid connected inverter.  This inverter is also connected to the mains supply in order to balance the supply to the load as well as back to the grid.  Apex deals in highly efficient grid connected ¡®pure sine wave¡¯ inverters that use Maximum Power Point Technology (MPPT) for converting DC in AC current.
