Description

PHOTOVOLTAIC PANEL OBJECT OF THE INVENTION

The present invention, as expressed in the statement of this specification, refers to a photovoltaic panel in which the main objective is to provide it with its own energy storage.

It is another object of the invention to prevent power losses.

BACKGROUND OF THE INVENTION

The use of energy storage devices produced by renewable energy sources is known in the state of the art.

In general, these types of devices are intended for centralized storage for several solar panels, or even for a complete solar power plant.

These types of storage devices provide current sources, whose power control provides losses in obtaining power.

Consequently, the storage of the energy produced by photovoltaic panels produces losses of power obtaining a lower yield.

DESCRIPTION OF THE INVENTION

In order to solve the problems and achieve the aforementioned objectives, the invention has developed a new photovoltaic panel of the type comprising a plurality of photovoltaic cells, but with the novelty that it comprises at least one energy storage element arranged in the Photovoltaic panel itself, unlike conventional panels in which centralized storage is carried out and there is no panel that incorporates energy storage, which constitutes a great advantage by allowing energy to be stored in the panel itself, which also provides Greater stability

In

DESCRIPTION OF THE PREFERRED EMBODIMENT

Below is a description of the

fifteen

invention based on the figures discussed above.

The photovoltaic panel 1 of the invention is

consisting of a plurality of photovoltaic cells 2

in each of which an element of

storage consisting of a flat supercondenser 2,

twenty

for which each of them presents a geometry that

adapts to that of the photovoltaic cell 2.

To get energy storage in the

3 flat supercondensers, their negative poles connect

to the negative charge zone of its corresponding

25

photocell 2, and also the positive pole of

each flat supercapacitor 3 with the positive charge zone

of its corresponding photovoltaic cell 2, obtaining

the positive and negative terminals 4 by which

interconnects between the different photocells

30

photovoltaic 2 that constitute the photovoltaic panel 1,

as shown in figure 3.

In another embodiment (not shown) the

superconductor 3 has a geometry equal to that of

panel, in which case a mechanical fixation is made to the

35

   panel and a connection equivalent to that described

previously, that is, the superconductor is connected directly to the positive and negative panel output.
