Potential of solar energy What 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 Photovoltaic is the most elegant way of producing electricity · 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)

Potential of solar energy Grid-connected system – the main components 1 1 Solar modules 2 Array box 2 3 DC switch (optional) 4 3 5 8 4 Inverter 6 7 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.
