Abstract
The disclosure relates to a solar module, which includes a plurality of solar cells which are interconnected to generate a direct-voltage power at module terminals, and a receiving unit for receiving an accurate time signal. The solar module further includes a communication unit for the synchronous transmission of the received accurate time signal to an inverter. The inverter is connected to the solar module by means of direct-voltage lines. The disclosure also relates to an assembly that can be integrated into a solar module, and to an energy generation system having a solar module of this type.
Claims14
A solar module comprising:
- a plurality of solar cells connected together to generate a DC power applied to module terminals,
- a receiving unit configured to receive a precision time signal, and
- a communication unit configured to time-synchronously transmit the received precision time signal to an inverter connected to the module terminals of the solar module via DC lines.
A solar module-integrable arrangement, comprising:
- a receiving unit configured to receive a precision time signal;
- and
- a communication unit configured to transmit the received precision time signal to an inverter connected to the solar module via DC lines.
A power generation system comprising:
- a solar module comprising:
- a plurality of solar cells connected together to generate a DC power applied to module terminals,
- a receiving unit configured to receive a precision time signal, and
- a communication unit,
- an inverter connected to the module terminals of the solar module via DC lines,
- wherein the communication unit is configured to time-synchronously transmit the received precision time signal to the inverter, and
- wherein the inverter is configured to detect a point in time with a fixed phase reference within a voltage profile of a connected grid, wherein the point in time is related to the precision time signal.
