The present invention refers to a flexible infrastructure solution, which allows the protection of flexible photovoltaic plate cables.
The solution consists of a cut for insertion of the ends of the cables and a jacket over the region of the cut, thus protecting the ends of the cables.
Power generation systems using photovoltaic plates, installed on roof structures of houses, buildings, sheds and other surfaces, are well known for converting solar radiation into electrical energy.
Photovoltaic plates are typically placed on a support surface, such as a roof, and directed towards the light, and the electrical energy produced must be transmitted through cables that start from the photovoltaic plate. These cables add complexity to the system as it requires proper positioning so that it is not loose and protected from adverse weather conditions, such as wind and rain.
For this reason, there is the need to provide protection to this wiring of the photovoltaic plates to obtain constant power generation.
The patent literature already has some suggestions to solve this problem, however, they differ from the present invention in several aspects.
Documents US 2019/219196 and US 2019/341882 describe devices for managing photovoltaic plate cables to be mounted on support surfaces, such as roofs or rails, thus avoiding contact of the wiring with the external environment.
The present invention differs from these solutions in that it is specific for use on flexible surfaces, while documents US 2019/219196 and US 2019/341882 are directed to more rigid surfaces.
Document US 2019/379322 describes a solution for cable management on roofs composed of Shingle tiles, where the cables are hidden under the photovoltaic plates and between the tiles.
The present invention differs from this solution by being specific for use on flexible surfaces and not on rigid surfaces.
Therefore, the present invention is innovative compared to the current state of the art and even if a specialist were to combine these teachings, the solution proposed by this invention would not be reached.
The object of the present invention is a photovoltaic module with a protective zone comprising:
An additional object of the present invention is a photovoltaic plate cable protection method comprising the steps of:
The following description is intended only to exemplify some of the numerous ways of carrying out the invention, and should not be viewed as limiting the scope of the present invention.
When developing the solution, it was identified that it solves problems related to the integrity of the cables, since they are not exposed to the environment. In addition, the present invention provides advantages such as protection against the infiltration of water that falls on the photovoltaic module, such as rain, which commonly uses the wiring as a guide to infiltrate the electrical system (electrical panels and battery banks) associated with the photovoltaic module, damaging it.
