  • photovoltaic modules are devices which convert solar energy into electrical energy, in particular with the aid of solar cells.
  • DE 10 2004 025 924 A1 describes a photovoltaic system for feeding energy into an electrical network.
  • This photovoltaic system has an integrated monitoring device, which monitors the status of the photovoltaic system and has means for sending status or error messages, in this document it is proposed, inter alia, to monitor the status of the photovoltaic system and status or error messages using GSM or UMTS module.
  • the photovoltaic system is intended to feed the energy generated into an electrical grid. On the other hand, it is not intended to provide energy directly to end users against payment.
  • the customer first has to buy a card on which a code is printed. With this code, the customer can redeem the credit balance on the card at an energy supply point of the associated energy provider. For this purpose, he must send a short message (SMS) with the code and the number of the electricity meter of the energy source that he wants to activate with his mobile phone. He then receives - again by short message (SMS) - a 20-digit activation code, which he must enter at an input device of the electricity meter. The customer is then supplied with energy until the credit balance acquired with the card has been used up. To reactivate the energy supply, he has to buy a new card and repeat the process (see http://www.conloq.co.za/pages/News/Brochure POWERcard.pdf and DE 698 03 278 T2).
  • SMS short message

  • the invention has for its object to provide a photovoltaic module and a method for controlling a photovoltaic module available, which allow a simple and flexible delivery of energy to third parties.
  • An inventive photovoltaic module has a connection for direct energy delivery to a customer and a controller.

  • a connection for direct energy delivery to a customer for example, a conventional socket or other connection for energy delivery understood, for example, a power cable or a USB cable.
  • Direct is understood to mean any energy output that takes place without being fed into an energy grid.
  • energy delivery within the meaning of the invention should still be considered as “direct” if the energy is first output to an energy store and later delayed by the energy store to the customer.
  • the term "coupled” should be understood to mean that the telecommunications module is either directly or indirectly in communication with the switch and can control this. Direct is the connection, if no other module or other element is connected between the telecommunication module. Indirectly, the coupling is already when, for example, a central CPU between telecommunications module and switch is arranged. Regardless of the examples described above, any other possibility of influencing the switch by the telecommunication module is also understood as coupling in the sense of the invention.
  • the photovoltaic module according to the invention has the advantage that the customer can take energy as needed, without preparatory actions are required. The customer does not have to conclude a contract with the owner of the photovoltaic module, nor is it necessary to purchase a magnetic card, a token, a value coin or any other item.
  • a billing of the photovoltaic module taken energy can be done via the telecommunications provider of the phone, with which the energy release was activated.
  • the invention makes it possible to purchase any amount of energy in a simple and user-friendly manner. This is particularly advantageous in areas where there is no power grid or in which the existing power grid is so unreliable that an alternative power source is regularly useful.
  • a further advantage of the invention is that customers can also remove very small amounts of energy from the photovoltaic module without first having to pay a "base amount". The use of a photovoltaic module according to the invention is therefore also suitable for customers with a very low financial budget.

This is particularly the case when mobile devices such as mobile phones or other electrical devices with accumulators are completely or partially discharged or only a limited time is available for energy delivery. Taking energy as needed can also be beneficial if the customer has very little financial resources and wants to ensure that energy is only purchased for the main consumer (s).
