SOLAR ENERGY IS A WIDELY AVAILABLE POWER SOURCE.

SOLAR ENERGY IS A WIDELY AVAILABLE POWER SOURCE.

It is a source of inexhaustible flow of energy that stimulates research and development for the use of every application.

Comes from the sun radiation and is converted into thermal or electrical energy.

The PV system is a set of chemical, electrical and electronic components combined to capture and transform solar energy into usable electricity. It is achieved using the photovoltaic effect.

When photons (energy particles from the sun) hit a PV cell, some energy is absorbed by the material, while some electrons flow though the material itself, which is a semiconductor producing DC (direct current) collected on the surface of the cell.

The cells are interconnected in series or in parallel to form a module, the basic component of any PV system. Modules can be connected together to build electric power plants.

PV systems can be classified as:

Grid-connected plants: when they are connected to the grid

Stand-alone plants: when they are not connected to the grid
