Our PV systems are thought through in the truest sense of the word. And so the crown sun is made optimal to flow.
Photo comes from the Greek word for light, phos. The term voltaic can be traced back to the famous Italian electricity researcher Alessandro Volta, who walked the earth from 1745 to 1827. Photovoltaic roughly means: “Electricity from light”. That’s exactly what a Krone Sonne system does: it generates climate-friendly airflow from light, even when it’s cloudy. The smallest part of such a system is the solar cell, which consists of dark blue to black silicon discs. Many electrically connected solar cells are in turn connected together in a module and protected against environmental influences by modern plastics.
This is how solar cells work
But what happens when light hits a solar cell? Well, positive charge carriers accumulate on one pole, negative charge carriers on the other – plus and minus poles. These charge carriers are collected by contact fingers on the cell surface and redistributed via cables. An energy potential is created in the form of an electrical voltage. If you close the circuit between the poles, current will flow, more specifically direct current.
So that you can use the energy in the household or feed it back into the grid, it is then converted into standard alternating current using an inverter and can be used directly in the household (self-consumption). The unused surplus is returned to the public grid.
In this way, solar cells become real energy packages
In principle, a grid-connected solar system works simply: when light falls on the solar cells, they generate direct current. The individual solar cells are connected to each other to form solar modules, which the hard-working Krone Sonne installers install on the customer’s roof. Depending on the size, up to two module fields (with their own orientation or slope) can be realized to optimize the yield. The blue or almost black color seen in the plants is silicon. Or almost – silicon is actually gray. But on top of the silicon is a layer that absorbs the light so that nothing is lost. This layer makes the silicon appear blue or black.
The current that comes out of the socket later is generated in the silicon. How is that done? Silicon is a “semiconductor”. Semiconductors conduct electricity – but (so semi) only under certain conditions. The stream is a stream of atoms. They are connected at the edges to form a lattice that contains even smaller particles – the electrons. When these flow from atom to atom, it is electricity.
The cells are so functional that they generate electricity even in bad weather or when it is cloudy. However, the current is always proportional to the intensity of the incident light. The higher the solar radiation, the more solar energy is produced by the PV system. Read more about Krone Sonne HERE.
