Description

    METHOD FOR INTERACTING WITH A SOLAR PANEL CONTROL DEVICE
  • The present invention pertains to a method for interacting with a solar panel control device through a television set.
  • Maximum power point tracking (MPPT) refers to the technique aiming at getting the maximum possible power from one or more photovoltaic devices, typically solar panels. For obtain maximum electric power from a solar power generation system, it is important to efficiently find out the maximum power point (MPP) of a solar battery.
  • The output characteristics of a solar battery changes rapidly from hour to hour depending on the amount of solar radiation and the temperature. Due to this fact, the solar power generation system should continually be monitored and the solar battery should be operated at a power point with the maximum output.
  • In other words, the load is monitored and the dynamic quantity which changes depending on the level of illumination as well as other factors such as temperature and the age of the cell are monitored so that it is ensured that the power drawn will not be less than the maximum available. In this way, the solar panel is used as efficiently as it could be. Maximum power point trackers utilize different types of control circuit or logic to search for this point and thus to allow the converter circuit to extract the maximum power available from a cell.
  • The present invention provides a method for interacting with a maximum power point tracker, the latter overseeing a solar panel through which a television is energized. The solar panel is controlled by said maximum power point tracker controller such that operation of the solar power generation system comprises the steps of determining a maximum power point of said solar battery. In this procedure, several operational parameters are provided to users by means of said television set being energized by said solar battery.
  • The present invention therefore provides a method for obtaining operational data in relation to a solar panel powering a television utilizing a maximum power point tracking controller as defined in the characterizing portion of Claim 1.
  • Primary object of the present invention is to provide a method for obtaining operational data in relation to a solar panel powering a television utilizing a maximum power point tracking controller.
  • The present invention proposes a method according to which operational data of a solar panel controller by a maximum power point tracking controller is obtained by a television and such data is communicated to users as often as necessary, i.e. when user intervention is required or preferred. Communication of solar panel operation parameters to a user directly on the television set has the advantage that a given user can monitor operational parameters such as solar panel current and voltage values, solar battery current/voltage, temperature values and solar battery level. These can be obtained in the form of curves. Further, warning messages as well as error messages are provided to the user on the television screen. Such messages may comprises excessive or too low battery voltage, excessive temperature or overload messages.
  • Accompanying drawing is given solely for the purpose of exemplifying the technical approach of the present invention whose advantages were outlined above and will be explained hereinafter in brief.
  • The drawings are not meant to delimit the scope of protection as identified in the claims nor should they be referred to alone in an effort to interpret the scope identified in said claims without recourse to the technical disclosure in the description of the present invention.
  • Fig. 1 demonstrates a block diagram of a power generation system comprising a solar panel powering a television.
  • Fig. 2 demonstrates a typical power/voltage curve of a solar panel in a power generation system.
  • Referring now to the figure outlined above, the present invention proposes a method for obtaining operational data in relation to a solar panel powering a television utilizing a maximum power point tracking controller as defined in Claim 1. Fig. 1 demonstrates the basic relation between output power and voltage of a solar panel.
  • The following numerals are assigned to different parts demonstrated in the drawings:
  • (1) Television
  • (2) Maximum power point tracking controller
  • (3) Solar panel
  • (4) Solar battery
  • As use and general principles of operation of a maximum power point tracking controller (2) for a solar panel (3) is known to the person skilled in the art, maximum power point tracking can be carried out and dynamic load adjustment can be applied by changing the duty cycle of the PWM output.
  • According to the present invention, operational data such as solar panel (3) current and voltage values, solar battery (4) current/voltage, temperature values and solar battery (4) level are communicated to said television (1) in the form of readable text or visual information consisting of text messages and/or voltage/current and temperature curves over time.
  • The fact that this information is directly conveyed to users via television (1) has the main effect of timely delivery of significant information. But, additionally, users are allowed to interact with the maximum power point tracking controller (2) and can accordingly set certain parameters such as location information of the solar panel (3). A mechanical arrangement of stepper motors such that a first stepper motor controls the vertical angle of the panel whilst a second one rotates a platform on which the solar panel (3) is mounted is used provides an improved solar energy. A malfunction in relation to the solar panel (3) pitch arrangement can also constitute an important information to be delivered to a given user.
  • The present invention provides a method for obtaining operational data in relation to a solar panel (3) powering a television (1) utilizing a maximum power point tracking controller (2), said method comprising the steps of monitoring said maximum power point tracking controller (2), obtaining operational data in relation to said solar panel (3) from said maximum power point tracking controller (2) and communicating said operational data to said television (1) in the form of textual and/or visual indications.
  • The technical advantage of the method of the present invention lies in that it does not necessitate technical proficiency to evaluate generated textual or visual information. Warning or error messages are accordingly used to inform of an important event such as excessive heating. Basically, a television (1) directly fed by the solar panel (3) is controlled by the MPPT controller (2) such that technical parameters in respect of the solar panel (3) are provided on the television (1) screen.
  • Further, the present invention provides that said textual indications are defined as character sets and transformed into audible sound. This is advantageous as audible signals may attract more attention and accelerate user intervention.
  • The fact that the operational parameters of the solar panel (3) are communicated to the television (1) which is fed by the same solar panel (3) has implications such that important information should be communicated to the users before a potential malfunction. Therefore the method of the present invention ensures that any operational data, which may be indicative of an operational malfunction is communicated either by turning on the television (1) or by interrupting broadcast.
