Potential of solar energyWhat is Photovoltaics (PV)?

Photovoltaics means turning daylight directly into dc electricity

Done by photovoltaic cells (PV cells), assembled into PV modules

There are no moving parts There is no 'fuel', apart from daylight The modules need no maintenance In principle, almost indefinite lifetime

PV works with both direct sunlight and indirect daylight (more light = more power)

Photovoltaic is the most elegant way of producing electricity

Potential of solar energyGrid-connected system – the main components

5 AC switch (optional)

6 Energy meters

7 House distribution box

8 Net connection Connected in parallel with the public network The systems work as small distributed power plants The system does not have any energy storage – the grid

serves as an energy storage balancing the load and production mismatch.
