inverter 48v 220v 6kw off grid

The main component of a solar cell is the semiconductor, as this is the part that converts light into electricity. Semiconductors can carry out this conversion due to the structure of their electron energy levels. Electron energy levels are generally categorised into two bands: the ‘valence band’ and the ‘conduction band’. 

The valence band contains the highest occupied electron energy levels, whilst the conduction band contains the lowest unoccupied electron energy levels. #24v 5kw solar inverter      The energy difference between the top of the valence band and bottom of the conduction band is known as the ‘band gap’ (Eg). 

In a conductor, there is no band gap as the valence band is not filled completely - #mpp solar inverter     thus allowing the free movement of electrons through the material. 

Insulators have very large band gaps which require copious amounts of energy to cross – and as such, inhibits the movement of electrons from the valence band to the conduction band. 

Conversely, the band gap in semiconductors is relatively small, #pure sine invert     enabling some electrons to move to the conduction band by injecting small amounts of energy.
