The system has a power line communication (PLC) directly integrated with a structure of an inverter in an inviolable manner, where the inverter is equipped with another PLC to exchange information with a monitoring center via alternating current (AC) power circuit. Information relating to origin of each solar panel is transmitted via a PLC power network, a continuous network, the two PLCs and the AC power circuit towards the monitoring center to detect fraudulent origin.

Description

/3 Système anti vol de panneaux solaires utilisant un système d'alarme via le réseau d'échange de puissance 1 Domaine technique de l'invention L'objet de cette innovation porte sur les panneaux solaires utilisés pour générer de l'électricité, en particulier les panneaux solaires intégrés dans l'habitat pour en réduire l'empreinte écologique. Un des principaux risques liés à ces panneaux est le risque de vol, ceux-ci étant, par définition, exposés à l'extérieur des immeubles et donc facilement accessibles et démontables. L'objet de l'invention est de proposer un moyen permettant de repérer, de manière facile et pratiquement incontournable, les panneaux solaires volés pour dissuader la création d'un marché « gris » écoulant les panneaux volés en les mélangeant avec des panneaux légalement achetés. BACKGROUND OF THE INVENTION The object of this innovation relates to the solar panels used to generate electricity, in particular solar panels integrated in the habitat to reduce the ecological footprint. One of the main risks associated with these panels is the risk of theft, these being, by definition, exposed outside the buildings and therefore easily accessible and removable. The object of the invention is to provide a means for identifying, in an easy and virtually unavoidable way, the stolen solar panels to deter the creation of a "gray" market selling the stolen panels by mixing them with legally purchased panels .

2 Etat de la technique antérieure Actuellement, les panneaux solaires sont des capteurs passifs qui ne disposent pas de dispositif facile et robuste permettant de détecter, lors de leur intégration dans une installation de génération de courant, leur origine douteuse. Il est donc facile d'écouler les panneaux volés, seuls une vérification systématique in situ, par exemple en relevant les numéros de série permettant, éventuellement, de le faire, de manière peu pratique, peu fiable, coûteuse et non systématique. L'objet de la présente invention est de remédier à cette carence en offrant une solution simple et efficace d'intégrer de manière systématique un système d'alarme dans chaque panneau permettant de détecter et de lancer une alarme, via le réseau de transmission de puissance auquel l'installation de panneaux solaires est reliée, si son origine est douteuse où si on tente de le voler. PRIOR ART Currently, solar panels are passive sensors that do not have an easy and robust device for detecting, when they are integrated into a power generation installation, their doubtful origin. It is therefore easy to dispose of the stolen panels, only a systematic verification in situ, for example by raising the serial numbers to possibly, to do so, impractical, unreliable, expensive and not systematic. The object of the present invention is to remedy this deficiency by offering a simple and effective solution to systematically integrate an alarm system in each panel for detecting and launching an alarm, via the power transmission network. to which the installation of solar panels is connected, if its origin is doubtful or if one tries to steal it.

3 Exposé de l'invention La présente invention est basée sur l'utilisation des technologies d communication via les circuits de puissance « Power Line Communication (PLC)» qui utilise les réseaux de puissance comme réseaux de communication entre les appareils électriques qui les composent. Plus particulièrement, cette invention porte sur l'utilisation de systèmes miniaturisés pouvant être intégrés dans les appareils électriques tels que ceux développés par la société Watteco. On pourra utilement se reporter au site web de cette société, www.watteco.com, pour trouver plus de détails sur cette technologie. Ces systèmes de communication, via le réseau de puissance, se présentent sous la forme d'un circuit électronique de quelque centimètre carrés, de quelques mW de consommation électrique, et faisant l'objet d'une fabrication en grande série, sont d'un coût abordable. Ils peuvent 10 15 20 25 5 15 20 25 2951574 2/3 donc être facilement intégrés dans la structure même de chaque panneau solaire lors de leur fabrication en rendant leur démontage ou modification impossible sans détruire l'intégrité du panneau. Une fois fabriqué, le panneau solaire est ainsi muni d'un moyen de communication pratiquement inviolable, qui lui permet de stocker et échanger, via le réseau de puissance, toute information le concernant. On notera que ces informations ne se limitent pas à la traçabilité et l'alarme en cas de vol : le PLC peut aussi transmettre les paramètres techniques permettant d'optimiser l'exploitation du système (par exemple évolution du rendement permettant de déclencher de manière optimale les opérations de maintenance (nettoyage...). On notera que : - les panneaux solaires produisent du courant continu, alors que la plupart des utilisations se font sous forme de courant alternatif : ils sont donc couplés à un onduleur ; - l'énergie solaire, tout comme, la plupart du temps, la consommation d'électricité par les utilisateurs, étant intermittente, ils est donc habituel, dès que cela est techniquement et économiquement possible, de coupler l'installation au réseau électrique pour pouvoir importer ou exporter du courant avec celui-ci chaque fois que la production des panneaux est en déséquilibre, dans un sens ou dans l'autre, avec la consommation. L'invention consiste, voir figure 1 donc à intégrer : Dans chaque panneau solaire (1), un PLC (2) utilisant le réseau de puissance en courant continu (3) le reliant à l'onduleur (4) pour échanger des informations avec celui-ci ; Dans l'onduleur (4) : - un PLC (5) échangeant avec les différents PLC intégrés dans les panneaux solaires via le réseau en courant continu (3) ; - un PLC (6) communicant avec le PLC (5) et échangeant avec l'extérieur, et en particulier vers un centre de surveillance (8), via le réseau électrique en courant alternatif (7). SUMMARY OF THE INVENTION The present invention is based on the use of communication technologies via Power Line Communication (PLC) power circuits that use power networks as communication networks between the electrical devices that compose them. More particularly, this invention relates to the use of miniaturized systems that can be integrated into electrical appliances such as those developed by Watteco. We can usefully refer to this company's website, www.watteco.com, to find out more about this technology. These communication systems, via the power network, are in the form of an electronic circuit of a few square centimeters, a few mW of power consumption, and the subject of mass production, are of a affordable cost. They can therefore be easily integrated into the actual structure of each solar panel during their manufacture by making their disassembly or modification impossible without destroying the integrity of the panel. Once manufactured, the solar panel is thus provided with a virtually inviolable means of communication, which allows it to store and exchange, via the power network, any information about it. Note that this information is not limited to traceability and the alarm in case of theft: the PLC can also transmit the technical parameters to optimize the operation of the system (eg performance evolution to trigger optimally maintenance operations (cleaning ...) It should be noted that: - solar panels produce direct current, whereas most uses are in the form of alternating current: they are therefore coupled to an inverter; solar, as, most of the time, the consumption of electricity by the users, being intermittent, it is therefore usual, as soon as it is technically and economically possible, to couple the installation to the electric network to be able to import or export electricity. current with it whenever the production of the panels is in imbalance, in one direction or the other, with the consumption The invention consists, see figu re 1 therefore to integrate: In each solar panel (1), a PLC (2) using the DC power network (3) connecting it to the inverter (4) to exchange information therewith; In the inverter (4): - a PLC (5) exchanging with the various PLCs integrated in the solar panels via the DC network (3); - A PLC (6) communicating with the PLC (5) and exchanging with the outside, and in particular to a monitoring center (8) via the AC power network (7).

On notera que, de la même façon que pour les panneaux les PLC (5) et (6) peuvent être intégrés, de manière pratiquement inviolable, à la structure de l'onduleur (4) lors de sa fabrication. On notera de plus que cet onduleur peut être installé à l'intérieur de l'habitation ou d'un local fermé au public, et est donc ainsi moins exposé au risque de vol. 30 4 Indication de la manière dont l'invention est susceptible d'application Nous allons indiquer maintenant comment l'invention est susceptible d'application. 5 10 2951574 3/3 Lors de sa fabrication, les informations concernant chaque panneau (1) telles que n° de série, client, etc...sont stockées dans le PLC (2). Lors de la mise en service de ces panneaux et la connexion de l'onduleur au réseau alternatif, ces informations peuvent donc être transmises via le réseau continu (3) puis les PLC (5) et (6) et le réseau alternatif (7) vers le centre de surveillance (8). Ce centre de surveillance peut alors détecter si certains des panneaux (1) connectés à l'onduleur (4) sont d'origine frauduleuse et lancer les actions correspondantes. L'onduleur peut, de plus, être programmé pour mettre hors service tout panneau d'origine frauduleuse qui lui serait connecté. De même, par la suite, une fois l'installation faite, en cas de tentative de vol de panneaux, le démontage de ceux-ci sera détecté, en temps réel, dès que la communication entre les PLC (2) et (5) ne pourra plus se faire, la liaison via le réseau (3) étant perdue. L'onduleur (4) pourra alors déclencher une alarme non seulement au niveau de l'habitation mais aussi, via le PLC ( 6) et le réseau (7) vers le centre de surveillance (8). On notera que ces opérations de surveillance se faisant de manière continue, automatique et systématique, on réduit de manière drastique le risque de vol de panneaux solaires équippés suivant l'invention. It should be noted that, in the same way as for the panels, the PLCs (5) and (6) can be integrated, in a practically inviolable manner, with the structure of the inverter (4) during its manufacture. Note also that this inverter can be installed inside the house or a closed room to the public, and is thus less exposed to the risk of theft. 4 Indication of how the invention is susceptible of application We will now indicate how the invention is capable of application. During its manufacture, the information concerning each panel (1) such as serial number, customer, etc. is stored in the PLC (2). During the commissioning of these panels and the connection of the inverter to the AC network, this information can be transmitted via the continuous network (3) then the PLC (5) and (6) and the AC network (7). to the monitoring center (8). This monitoring center can then detect if some of the panels (1) connected to the inverter (4) are of fraudulent origin and launch the corresponding actions. In addition, the UPS can be programmed to disable any fraudulent original sign that is connected to it. Similarly, after the installation is done, in case of attempted theft of panels, the disassembly of these will be detected, in real time, as soon as the communication between the PLCs (2) and (5) can no longer be done, the connection via the network (3) is lost. The inverter (4) can then trigger an alarm not only at the home but also via the PLC (6) and the network (7) to the monitoring center (8). It should be noted that these monitoring operations are continuous, automatic and systematic, drastically reduces the risk of theft of solar panels equipped according to the invention.
