MOBILE DEVICE FOR PRODUCING PHOTOVOLTAIC ENERGY

Description of the invention

Technical area

The present invention relates to an autonomous mobile transportable installation for producing photovoltaic energy, comprising a plurality of panels.

photovoltaic cells (1) encased in rectangular frames (2), mounted on a supporting structure (S), all forming a compact assembly, and a current converting device (3).

Prior art

[0002] There is no direct antecedent of the subject of the invention because the energy

Photovoltaic throughout history has always been linked to fixed and terrestrial installations.

Currently, many devices and means are known to install photovoltaic panels (1) on different types of surfaces, as are: roofs of buildings or plains of land. In this sense, we can cite, photovoltaic farms in plains of land anchored on it by means of different processes, as could be the one of shooting soles, or farms

photovoltaic on roofs of halls or buildings by making anchorages on the own structure of the building.

Currently, development work prior to these facilities

Photovoltaic, are essential, heavily stress on the cost of their realization, concern in particular the following phases:

→ Possible adjustment of access;

→ possible preparation of the ground (leveling and earthworks);

→ Laying the foundations of the modules. Depending on the geotechnical quality of the ground, light structures (steel piles beating in the ground) or heavier foundations (concrete footings for example) will be put in place; → Security work (closure, surveillance);

Foundations for heavy loads with concrete sleepers prepared on site are used when the ground is resistant to threshing (large block remaining old foundations, sleepers, remains of roads, etc.) and when residues do not allow to drive stakes into the earth.

In some extreme cases, it will be necessary to seek a design office that will determine the nature of the soil and establish a foundation plan according to the mechanical constraints of the facility.

In general, the connections between the frames (2) of the panels (1) and the inverters (3) are made using buried cables. The cables are laid on a layer of 10 cm of sand at the bottom of a trench dedicated to cables with a depth of 70 to 90 cm. The cables are laid side by side, usually in sleeves, the distance between the cables and the width of the trench depending on the intensity of the current to be expected and the location of the technical room that is supposed to house the other equipment.

• [0008] The project usually lasts between 2 and 5 days to physically realize a fixed photovoltaic installation, it depends on the size and complexity of the installation and the number of speakers; this frequently countable period outside the civil engineering works.

[0009] Ordinarily, a photovoltaic system comprises:

A photovoltaic solar module comprising at least one photovoltaic panel (1), such a module defining a photovoltaic field (Cp) contained in a plane P;

- → a supporting structure or a support (S) intended to mount or install the photovoltaic module and the other components of the system;

- an inverter (3), that is to say an electrical device used to convert into AC current, the continuous electric current produced by the photovoltaic panels

(D;

→ optionally a battery (4) for storage in form

chemical energy produced by the photovoltaic panels (1), to return it in electrical form as needed (for example at night or on days covered);

-> and a controller constituted by an electrical device that manages the storage of

the energy in the accumulators and the distribution to the load (that is, which controls the charging and discharging of the accumulators).

[0010] Conventionally, the components of such a photovoltaic system consist usually and only of:

-> a photovoltaic panel (1) is constituted by a serial / parallel assembly of cells. It is a DC generator delivering a voltage of 12, 24 or 48 volts. The power of a panel (1) is between 10 and 300 Wc. The solar panels (1) are then assembled in series / parallel to form a photovoltaic field (Cp). The power of the field (Cp) corresponds to the number of panels (1) times the unit power of a panel (1) and is expressed in Wc or kWc. Manufacturers guarantee their products; the performance of the panel (1) namely: 90% guaranteed yield at 10 years and 80% guaranteed return at 20 or even 25 years depending on the manufacturer.

→ the power of a panel (1) varies according to the sun's illumination, the cell temperature (the colder the cell, the better the efficiency). Beware of the phenomena of shadows, masks near or far (tree, building, ...) because the power can decrease strongly for a small surface of shadow.

→ The inverter (3) or rather the converter: this device converts the direct current (DC) produced by the panels (1) into alternating current (AC) according to the

characteristics required. The dimensioning of the inverter (3) must be carried out in accordance with the power of the photovoltaic field (Cp) and must be between 0.7 and 1 times the power of the photovoltaic field (Cp). The inverter (3) works in search of the maximum power point to always seek the maximum operating point (this will depend on the torque

orientation / inclination, illumination, possible shadows, etc.) ■

- The efficiency of the inverter (3) is 97 to 99% and the conversion efficiency DC / AC is 92 to 96%. The product warranty of an inverter (3) is 5 years but it is possible to find guarantees of 10 years or even 20 years. The inverter (3) must be installed in a ventilated room (the efficiency will decrease according to the heat), easy to access for maintenance and close to the photovoltaic field (Cp) to limit line losses. Depending on the building, it will be necessary to choose either inverters (3) inside or inverters (3) outside. The inverters (3) can be either single-phase for a single-phase connection or three-phase or three-phase for a three-phase connection. At the output of the inverter (3), the power is expressed eh Voltampere or VA (or kVa), it is the power of injection.

[0011] The installation can also be designed so that the battery (4) and the charge controller can be separated from the unit of the solar panels (1), and then again assembled with it, when the electrical energy must be used at night for a limited time.

The photovoltaic installations systematically require a technical room, housing in particular the inverters (3), the accumulators (4) and the charge controllers, and a fence; The facilities are fenced to prevent depredations, the passage of wild animals and especially theft of photovoltaic panels (1).

To be profitable, once assembled, the photovoltaic installation must be able to last in time and in particular withstand bad weather. Thus, a critical aspect of this type of installation is its ability to accommodate dilations and retractions related to temperature differences.

These photovoltaic installations are often carried out above the buildings, the photovoltaic panels (1) are arranged adjacent to each other on a rigid support (S), formed of profiles, and which makes it possible to maintain the panels.

photovoltaic (1) in a fixed position. The photovoltaic panels (1) are oriented in a predetermined manner so that the angle formed between the photovoltaic panels (1) and the rays of the sun is optimal for the highest possible yield of the photovoltaic installation.

[0015] Generally photovoltaic installations are often carried out near the site where the equipment to be connected are installed and remain strengthened at this level since it is the only source of energy for their operation.

[0016] Frequently the photovoltaic installations are often designed for domestic and agricultural needs; their use in other sectors remains limited, given the nature of the respective activities on the one hand and the complex nature of their implementation on the other.

[0017] Most citizens today use diesel generators as a backup solution to supply remote areas of major consumption centers. The connection of these areas is in many cases very expensive. However, the transport of fuel in these areas presents great difficulties. In addition, the demand for electricity is so low that it is not possible to build large power stations. power to lower production costs; the hydrocarbon transport networks and the necessary electrical interconnections do not yet exist. These projects take time in their development and their placement requires significant funds.

[0018] However, many electric transport networks do not have trans-boundary interconnection, their extension covering, more often than not, a small part of these areas.

The greater distance of the latter and the low density of populations and public transport in rural areas explain the role of the automobile in opening up rural areas.

The connection between the villages is made difficult; these areas characterized by the hardness of their reliefs are isolated and inaccessible and on average during three to four months during the rainy season. The tracks remain the only alternative to access them.

The network of trails is exposed to the weather that hit these regions; the rugged terrain that characterizes them combined with heavy rainfall, cause landslides or cuts due to the streaming of water.

The increasing number of solar equipment generally constituting photovoltaic installations increases the risk of unauthorized manipulation, including the theft of such pieces of equipment which, because of their

functioning, are always exposed and sometimes installed far from homes. The damage can be considerable because it is very expensive.

The powerful and safe antitheft protection mechanisms are expensive and sometimes complicated to handle. They also prevent any manipulation, for example extension or replacement operations by the operator of the solar equipment.

Presentation of the invention

The present invention relates to an installation for producing energy at low costs.

The present invention provides a sufficient alternative to existing solutions for the continuous and massive production of low cost electrical energy, without pollution, without greenhouse gas emissions, without consumption of limited natural resources, without waste.

The present invention relates to a photovoltaic station, of high power, carried on a towable trailer (R), and aims to overcome the disadvantages described above including the cost, accessibility, opening up, security, assembly and dismantling, rehabilitation and repair, retraction and expansion due to temperature variations, efficiency and especially mobility.

A photovoltaic installation, similar to the present invention, comprises a number of photovoltaic panels (1) that convert light into electricity.

Each photovoltaic panel (1) is characterized by an electric power and a DC output voltage, also called DC current. For this it is necessary to transform the continuous electric current, produced by all the photovoltaic panels (1), with a voltage compatible with network standards, typically 380 volt AC (AC current).

This transformation is at the level of the conversion device (3).

The photovoltaic panels (1), placed on a support (S) designed for this purpose, are connected in series on a power supply cable, perfectly protected and arranged in cable trays, to connect the photovoltaic panels ( 1) to the conversion device (3).

The towable traveling trailer (R) was designed in the context of this invention for it to board in its compartments arranged for this purpose, the photovoltaic panels (1), their support (S) and their auxiliaries (6). (7) (8) (9) (10) (11) (12) (13) (14) (15), the connecting cables and the inverter (3).

It is obvious that the mobile device object of the present invention provides, depending on the choices made, power greater than those of conventional photovoltaic stations, and constitutes a power supply providing self-sufficiency for electrical needs other than traditional (habitat , agriculture), including industry, construction, campsites, enclave health centers ... etc. which usually require a power of 5 KW or more.

The sizing of this type of installation depends essentially on the payload and authorized trailer (R), in accordance with the applicable country regulations in force, especially the weight; the load shall not exceed the overall width of the trailer (R). The length of the load shall neither drag on the ground nor exceed the rear end of the trailer (R); which practice is avoided in the present invention.

The prototype presented in the context of this patent is of the type of installation procréant resolute powers in KW, according to the need expressed on the market and taking into account, of course, the volume of the trolley and the congestion tolerable according to to the laws and rules in application.

The trailer (R) towable being constituted by a body of various size made of commercial anticorrosive metal profiles.

The structure of this body is manufactured in profiling, bent to receive a dressing, fixed bolt and slightly by a microsoudure of quality, to prevent the formation of corrosive cord.

The balance of this trailer (R) is guaranteed by the stability of the vertical and horizontal plane, provided respectively by the cross of St. Andrew and by the provision of the various systems that are established there, particularly accumulation (4). ), current conversion (3), solar panels (1) and their support (S).

The dressing of said trailer (R) is made of either galvanized sheet and / or sandwich panels; other types of similar cladding are possible in this context; however they must necessarily meet the standards of quality and design.

The aeration (17) of the carriage is accomplished by openings made on its facades, created to passively ensure the release of procreate heat by the current conversion device (3) and particularly by the accumulation (4) . The front doors (16) and rear (18) to be fixed to the trailer (R), thanks to the importance of the substance used with which being manufactured (sheet, cladding, etc.) and reassortment of its components, are of one of the best qualities.

Higher quality materials have been used to make the closure systems and the hinge pins:

→ hinges anticorrosive alloy

→ The seal made of two components pôlyuréthâne

-> Rails to be mounted inside the door

→ Reversible door with screwed hinges.

→ The door (16) (18) is manufactured with a gutter profile preventing the infiltration of water and dust.

→ The formation of a corrosive bead caused by welding is considerably discarded, since the latter is very limited at this level, having been accomplished by a state-of-the-art application and the use of the highest quality processing substances, especially the welding rods.

The structure of the chassis of the trailer (R), of any size, being shaped by a frame eh UPN reinforced by bars IPE; the plate provided at this level ensures the fixing of the system of two axles (19), tolerant even a tonnage capacity which inevitably requires approval, usually issued by the relevant transport departments, on which are placed four wheels with tires (20) .

The towable trailer (R) object of the mobile device is equipped with a handbrake system; brake controls are provided for trailers towed by soft suspension vehicles. In case of use behind a heavy truck or a tractor, it is mandatory to install the ball joint mounted on the shock absorber to avoid any premature wear.

The jockey wheel (22) provided at this level, ensures the stability of the trailer (R); when the latter is hitched to the vehicle or when it is laden, it is advisable, for safety reasons, to remove the jockey wheel (22) from its support

The stability of the trailer (R) at a standstill is also ensured by four cranked feet (21), folded during the operating state.

The trailer (R) must be hitched horizontally by means of a hitch ball (23), in particular for trailers (R) with two axles (19). The four wheels (20) must be in contact with the ground whether the trailer (R) is empty or loaded. The load must be distributed so that the weight on the coupling is always less than the maximum weight allowed on the coupling head (23).

The trailer (R) is equipped with wheels (20) and a braking system that meet the standards of construction and use. It can therefore be towed at full load at the maximum authorized speed of 120 km / h.

The paint to be made at the trailer (R) tractable is epoxy polyester powder type

The solar panels (1) are carried on a support (S), designed to be easily removable from its trailer (R) carrier, to be placed on a floor adjacent to the latter. [0051] Specially, the object of the invention is the realization of a transportable installation of efficient solar energy production, which can be easily assembled and disassembled, and easy to transport.

The solar panels (1) of this installation are interconnected by assemblies and suspended from a support mounted on the frame, which framework has been scrupulously invented to protect them from damage during transport, so as to be able to deployed, folded and mounted easily on the support (S);

The structure of the latter (S) consisting mainly of:

→ Front base plate (9) for fixing the horizontal stability bars on the X (6) and Y (7) axis plus the rotating part for all the panels (1); → Rear base plate (10) for fixing the horizontal stability bars on the X (6) and Y (7) axis plus the counterweight mounting rods (11)

→ Horizontal stability bar in square tube (7) with drilling appropriate diameter on both ends (X axis)

→ Square tube horizontal stability bar (6) with hole diameter on both ends (Y-axis)

→ Vertical stability bar eh square tube (8) with drilling appropriate diameter on both ends (Z axis)

→ Counterweight plate (1 1) with lifting lug

→ Frame (2) for fixing panels (1)

→ Fastening with bolts (12), plastic washers (13), metal washers (14) and nuts (15)

→ The materials used for all these accessories are multiple and diverse, have been carefully studied and distinguished; quality parameters and weight optimization have been the basis of this range.

All of this structure (S) being hot-dip galvanized by the application of a melting coating and anti-corrosive alloy of superior quality.

The inverter (3) is a complex part of a photovoltaic system; it is relatively difficult to evaluate without going into very lengthy technical explanations. There are still things to know. First, the efficiency of an inverter (3) will depend on the input voltage and therefore on the output of the photovoltaic panels (1), and each inverter model has a different optimal operating point. This means that the inverter (3) must be dimensioned according to the number of panels (1), and their maximum power. Normally, if the inverter (3) is undersized, or

Oversized, we lose in yield. If it is undersized, it may also fail prematurely.

Then, it should be understood that the input voltage varies depending on the time of day, and again, each inverter (3) has a different yield curve depending on the deviation from the voltage optimal. Some models therefore lose less in performance when the power output of the panels is low, the morning and evening. Overall, they will be more effective on the whole day.

The durability of the inverter (3) will depend on its good size compared to the rest of the installation, but also its manufacturing quality, and its good

these two parameters are generally linked. Most of the big ones European, American and Japanese manufacturers are serious about this.

It remained the method of cooling, and there, there is controversy. Most manufacturers opt for passive cooling of the inverter (3), which implies a fairly large housing. In any case, it will be necessary to place the inverter (3) in a rather cool place (especially not outside in full sun). Passive cooling can be quite effective. Other UPS manufacturers (3) add a ventilation system, often with a smaller enclosure. This is not necessarily a bad solution from the point of view of cooling. By cons, it rests on a moving part, so more fragile, and if the fan stops, the inverter (3) will suffer.

The prototype of the mobile photovoltaic power device exposed for the purposes of illustrating the present invention, has previously taken into account in its design of the latter imperatives concerning the inverter (3) including the quality of its manufacture;

The power of the latter would be dominant to that generated by the panels

photovoltaic (1), so that the loss of efficiency, by which this equipment is characterized, would be the lowest and that its dimensioning is proportional and fair; the disposition which has been reserved for it and the ventilation of its location accomplished by openings (17) on the sides of the bodywork, seem to thwart the obligated bound to the clutter due to the importance of its weight and its dimensions and at cooling.

Cooling partially provided by the ventilation apertures (17) remains a convenient solution to continuously ensure the inert ventilation of the premises of the carriage; the efficiency of the current converting device (3) and that of

of accumulators (4), is depreciated in particular according to the heat and the sweltering of the place of their installation. By defeating this last imperative for good, an optional air conditioning system (5), or even air treatment, has been recommended for a good productivity, the dimensioning of the necessary air conditioning depends on the size of the trolley and also characteristics of the inverter (3) and those of the batteries (4)

In this photovoltaic system we have estimated that the cables must be carefully selected to avoid excessive power losses; the choice of wiring depends on the following main criteria:

→ Resistance to strong solar radiation (UV) and bad weather

→ Optimal section of cables to avoid a large voltage drop (better system performance)

→ The diameter of the cables

Furthermore, the main idea behind the invention is to design a competitive photovoltaic mobile device for the production and supply of sufficient solar energy, regardless of the equipment to connect to it. the opposite of fixed installations carried out only near the equipment, always immediately usable from the arrival on site, and without any possibility of error during the installation, its assembly and disassembly can be done in a simple and fast way . This system can truly be called a mobile solar "generator".

Without doubt, the mobile device invented, being a mobile "generator" solar mobile, presents an effective and competitive solution, unlike the diesel generator, commonly used today as a backup alternative in areas including more distant and most frequently, inefficient because of diesel and the other disadvantages of diesel.

The present invention designed in such a way that the mobile device of photovoltaic energy is accessible, in particular, in areas not sheltered by the trans-boundary electrical interconnections, their extension generally not covering, moreover moreover, that part of its territories.

Advantageously, it can be estimated that the mobile device of photovoltaic energy particularly considers the enclosed areas, including those characterized by the hardness of its reliefs.

The mobile device of photovoltaic energy, was invented to open up also, even inaccessible areas known for the impassability of their tracks and the violence of the rains that often cause landslides and cuts due to streaming of water.

Advantageously, it can be expected that despite these constraints, the mobile device of photovoltaic energy, will make the connection between the villages of these closed areas easier, including communities whose populations record a low density, This explains the role of mobility in opening up rural areas.

The invention also allows, by its peculiarity, to provide solar energy, distinctly during the same day, for multiple uses and multiple sites of use.

The attribute of this mobile device photovoltaic energy object of the present invention is that it is fast to mount on the support (S) on the final site of use, without requiring prior work anchoring or foundation, or even the possible commitment of a design office, necessary to ensure the horizontality of the structure, which is particularly advantageous in terms of cost.

The flatness defects of the carrier structure (S) are a well-known problem of the solar panels (1), and they constitute a major drawback to their use. The present invention provides an effective solution to this problem. Indeed, the flatness of solar panels (1) and the absence of mechanical stresses are provided by the interface itself, and not by the carrier structure (S) as is usually the case.

The mobile device foiled by this invention the mechanical stresses that necessarily appear in the carrier structure (S) of the modules during their movement and their implementation, and which are not transmitted to the solar panels (1).

The invention also allows the use without disadvantages for solar panels

(1), a carrier structure less rigid and therefore lighter and less expensive.

Thus, the solar panel (1) is suitably fixed to the supporting structure (S) to cope with the usual mechanical expansions and weathering.

Advantageously, it can be estimated that the fastening means provided in this context, are quick to implement, effective and inexpensive, and they reduce the time of assembly and disassembly.

Advantageously, it can be provided that the intermediate structure comprises integrated orientation means for orienting the solar panel according to at least one axis of orientation; the daily quality of solar light received by the solar panels (1) is improved; the orientation of the panels (1) can thus be programmed or controlled and takes into account the shading phenomenon considerably.

non-limiting example, will make it clear how the invention can be realized.

With reference to FIGS. 1 to 4, the subject of the present invention is a mobile photovoltaic energy device, loaded onto a towable trailer (R), comprising a plurality of photovoltaic panels (1), a carrier structure (S) of these, batteries (4) and an inverter (3) for transforming the continuous electric current produced by all panels, with a voltage typically 380 volts AC. The invention allows transport, even in isolated and unaffordable areas, and the delivery of a photovoltaic installation, easy and quick to mount and replicate, achievable immediately upon arrival on site, and without any chance of falsehood

the installation, applicable, regardless of the nature of the equipment to be connected with it, and employable, distinctly and simultaneously, in the same interval, for multiple applications and multiple sites.

Figures 1, 2 and 3 illustrate different views of the mobile device of photovoltaic energy according to a dominant embodiment of the invention.

[0081] Referring to Figure 1, the device of the invention comprises a trailer (R) rolling, provided with innate ventilation openings (17), equipped with a hinge ball (23) for its traction , carried on two axles (19) to four wheels (20) and strengthened stopping by four feet (21) and a jockey wheel (22), and folded in working order.

With reference to FIGS. 2 and 3, the compartments of the mobile device are designed in such a way that the horizontal (6) (7) and vertical (8) stability bars, the current conversion device (3) ), the accumulator batteries (4), the connector cables, the support plates (9) (10) and the counterweights (11) are respectively and methodically arranged at the level of the trailer (R); the photovoltaic panels (1) embedded in frames (2) as illustrated on the rear face of the trailer (R), are stored packed in landscape, in divided rows, so that they do not undergo no damage during transport and that their loading and

unloading is done in a convenient and easy way.

In general, all the auxiliaries of the present device are unloaded from the trailer (R), at the installation, with the exception of the current conversion device (3) and the storage batteries (4). ), by their characteristics, remain immobilized at their location distinctly provided with a ventilation (17) inert and optionally an air conditioning device (5), or even air treatment.

In a first embodiment, the mobile device for energy

photovoltaic, upon arrival on site, is parked near the place where the support structure (S) will be mounted, forming a photovoltaic field (Cp) for this purpose.

In a second embodiment, the hitch ball (23), however, is withdrawn simultaneously safely from the vehicle stretching with the killing of the trailer (R) performed by a manual park brake.

In a third embodiment, the trailer (R) is subsequently directed through its jockey wheel (22) with which the balance is largely ensured, so that its layout is clearly adjusted in joint ownership with the photovoltaic field (Cp), this is how the feet stand (21) are spread on the ground, to neutralize more the trailer (R) and ensure its stability.

The invention also relates to a method of mounting the photovoltaic field (Cp) of at least thirty-six photovoltaic panels (1) presaged, according to the embodiment of the prototype unveiled as a reference.

The method according to the invention, as described in Figure 4 consists of arranging the support (S) from a passive position to an active position. To do this, three configuration steps are inevitably achievable: → In a first configuration step, all the front support plates (9) are placed on the ground in correlation with the rear support plates (10), with a spacing almost prescribed by the lengths of the horizontal stability bars (6). ) (7).

→ In a second configuration step, the front (9) and rear (10) support plates are interconnected on the x axis by the stability bars (6) and on the y axis by the stability bars (7) and tied by bolts (12), plastic washers (13), metal washers (14) and nuts (15).

→ In a third configuration step, the rear support plates (10) are arranged to receive the counterweight (1 1), once the choice of orientation of this base is definitively determined.

The method subsequent to these various configuration steps mentioned above, according to the invention, consists in installing the first frames (2) in which the photovoltaic panels (1) are embedded in the lower row of the support (S), and then assembled. at the bottom, to the articulation pieces of the front support plates (9) and supported at the top by the vertical stability bars on the z-axis (8) placed in turn on the rotation graduation perpetrated at the bars horizontal stability of the y-axis (7).

According to a particular embodiment, the appropriate determination of the graduation to be operated at this level is formally recommended to obtain a better inclination for an adequate position of the support (S) to be oriented in a working position, in prescience of the phenomenon. shading. The expected working position is characterized by the fact that the XY laying planes of the frames (2) are aligned from bottom to top and from the middle to the ends. More specifically, as shown in Figure 4, each row is aligned with the other and so on until the conquest of the field

photovoltaic (Cp).

According to a last embodiment, the commissioning of the mobile device for photovoltaic energy is, however, declared operational as soon as the junction of the connector cables takes place:

→ Between photovoltaic panels (1) forming the photovoltaic field (Cp) → Between the photovoltaic field (Cp) and the current conversion equipment (3) and accumulation equipment (4)
