Feed-In Point

The feed-in point is the interface between a photovoltaic system and the public power grid. At this point, the electrical energy generated by the solar system is fed into the grid. The feed-in point marks the transition from private generation to the public power supply system.

Functionality:

1. Conversion: The direct current generated by the solar panels must first be converted into alternating current. This task is performed by an inverter, which is an integral part of every photovoltaic system.
2. Feed-in: The alternating current is conducted to the feed-in point through appropriate lines. This is usually located at the house connection or a nearby sub-distribution.
3. Measurement: At the feed-in point, a feed-in meter is installed. This measures the amount of electricity fed in and serves for the settlement of the feed-in tariff.

Importance:

The feed-in point is crucial for the remuneration of the generated solar power. According to legal regulations (e.g., Renewable Energy Sources Act in Germany), operators of systems receive compensation for the electricity fed in. The amount of this compensation depends on various factors, such as the installed capacity of the system and the time of commissioning.
