Photovoltaics
Function photovoltaics
Climate-friendly electricity for everyone. The real contribution to our environment.Your climate-friendly energy supply from the roof to the socket.
The principle of a grid-connected photovoltaic solar system is very simple:
As sunlight falls on the solar cells, they generate direct current from it.
The individual solar cells are interconnected to form larger solar modules. The individual solar modules are in turn interconnected to form a solar generator.

Simply explained for you:
"Photovoltaic systems consist of a number of photovoltaic modules, which in turn consist of photocells or solar cells.
In the solar cells, incident sunlight is converted into electricity.
The light consists of photons, the carriers of electromagnetic radiation."

Principle of photovoltaics in the sun and at night
Note:
Berlin's new solar law came into force in mid-July 2021. As of January 1, 2023, it makes solar mandatory for all new buildings (from 50 sqm of building floor space). At least 30 percent of the gross roof area must be used with photovoltaics or solar thermal energy (according to the Building Energy Act (GEG)) from this date onwards

Commissioning of the PV system
Consumers can use plug-in solar devices for private power generation up to a total output of 600 watts.
now register with the grid operator themselves, instead of via an electrician as was previously the case.

Energy point out. A new regulation of the standard VDE-AR-N 4105 makes this legally possible,
which came into force last Saturday.
Electricity meter must not turn backwards.
This is ensured, for example, by electricity meters with a backstop.
However, the conversion, usually by the network operators, had so far "oftenfaileddue to their lack of cooperation",
as only one procedure existed for the registration of power generation systems via electricians.
With the entry into force of the new VDE-AR-N 4105, all network operators would be obliged,
also accept the registration of plug-in solar devices up to 600 watts by laypersons.
Various grid operators had already translated this into their own reporting forms. For customers of "conservative grid operators
the German society for solar energy (DGS) developed a reporting form conformal with the new standard.
"The real goal, however, is a regulation for balcony solar systems like in Luxembourg.
There, such systems up to a power of 800 watts are exempt from any obligation to register.
