Principle of operation of photovoltaic solar panels

The photovoltaic phenomenon was discovered in 1839 by Edmund Bequerel, who noticed that the sun produces electrical energy under certain electrochemical configurations.

The photovoltaic phenomenon was started to be used to turn direct sunlight into energy since 1954. The principle is that when a photon reaches a semiconductor, then the negative transitional surface of the polarity ejects the electron thus two conductors are created: the free electron and the electron hole.

The released electrons flow to the upper layer. In the bottom layer the electrons are deflected from one atom to the other in a way that they fill the empty places. The free electrons are conducted from the upper layer into the electric field where the solar cell is located. This is how electricity is created in this area as long as sunlight reaches the solar panel.

Electricity is created without noise, in a clean way and without any by-products. The photovoltaic equipment operates automatically and without maintenance. Solar panels produce direct electrical current, which is converted to 230 Volt AC by means of an inverter (power conversion equipment). The solar power system is running in parallel with the electric provider's network.

The energy produced by our installed solar panel system is used and the surplus generated energy is fed back to the public grid, which amount is paid to us by the energy provider. All values of the produced energy are measured and managed.

The photovoltaic solar system is easy to install - even retrospectively - to the existing electrical system of the building. The generated clean energy does not pollute the environment, reduces gas emissions causing greenhouse effect, and it is important too, that we create significant cash inflow to ourselves.
