What is photovoltaic?
Photovoltaics: a cutting
Photovoltaics (PV) is a technology that converts light directly into electricity. The best known method for generating solar power is by using solar cells. PV cells require protection from the environment and are usually embedded in between glass sheets. When more power is required than a single cell can deliver, cells are electrically connected together to form a photovoltaic module (solar panel). One square metre of modules can produce an average of 100 W of power. Modules are connected together to produce the required electrical output.
The photovoltaic process: from solar radiation to grid-connected energy
Photons (01) are captured by photovoltaic cells (02) and converted into electrical current (03-04). Using an invertor (05) the electricity can be linked to the grid (06).
