- Photovoltaic panels have certain limitations such as sensitivity to shading and are subject to ageing.
- photovoltaic panels encapsulated for example with Ethyl Vinyl Acetate (EVA) can yellow/brown over time following exposure to UV.
- Ethyl Vinyl Acetate (EVA) can yellow/brown over time following exposure to UV.
- EVA Ethyl Vinyl Acetate
- This effect limits the exposure of the cells of the panel to light and therefore reduces its performance. This effect is included in the calculation of the rate of degradation of the producible of the panels, today around 0.5-0.7% / year. This degradation leads to having to replace the panels, which is a heavy operation.
- a conventional panel may no longer deliver part of the maximum power that can be supplied if part of its surface is no longer exposed to light.
- panels whose cells are connected in series with bypass diodes in parallel with groupings of cells for example models with 3 bypass diodes defining three groups of cells which represent the majority of current commercial products, 1/3 of the maximum power is lost as soon as a cell of a group is shaded, 2/3 maximum power is lost for shading on cells of two groups and all of the power is lost in the event of partial shading distributed over the three groups. This therefore leads to a loss of efficiency of the installations.
- the object of the present invention is therefore to propose a solution making it possible to solve the problems of aging and/or shading simply and making it possible to increase the efficiency and the producible of the existing panels without changing them.
- the main idea concerns a device consisting of an additional photovoltaic panel module which is installed and connected directly to an existing conventional panel, new or already installed, in order to increase the quantity of energy produced by the classic panel assembly - additional module.
- the additional module can in particular be based on the manufacturing flexibility of a panel in thin layer technology, in particular produced by structuring such as laser or other structuring to modify its electrical characteristics in terms of current and voltage in order to adapt to the different types of panels. existing ones on which the additional module can be installed.
- the additional module is designed to constitute a photovoltaic panel having an operating voltage equal to +/-10% to the operating voltage of the existing panel once the two associated systems, that is to say that an operating voltage VMPP of said existing panel or group of panels is determined once assembled with said one or more additional modules knowing the type of additional module that one wishes to use and in particular the transparency of this module at the frequencies necessary for the existing panel.
- Tandem-type cells based on silicon have a theoretical efficiency of around 43%. Tandem panels with around 30% efficiency are expected in the next few years.
- the method and the module of the present invention use a different technology from the existing panel to improve the performance of the whole.
- One possibility is the use of thin-film technology cells and/or structurable technology cells, for example using a laser, such as the CIGS, Perovskite, CdTe or hydrogenated amorphous silicon cell technologies known to this day. It can of course use any new technology of photovoltaic cells with at least partial transparency for the useful wavelengths for the existing panel which could emerge.
- the technology of structured cells allows the creation of a custom electrical architecture by alternating the phases of electrical insulation, such as laser etching, and electrical connection, such as the deposition of conductive film, and by making connections of series or parallel type.
- the module produced is semi-transparent, i.e. it allows light to pass in the wavelengths not absorbed by its cells, which can in particular make it possible to recover light energy at the level of the cells of the panel. when the additional panel module covers the existing panel on its side exposed to the sun.
- the module will be based on photovoltaic technology with a gap energy greater than existing panel technology.
- the module can then use Perovskite cells, with a band gap energy Eg e which can be defined between 1.2 and 1.9eV, CdTe cells with a band gap energy Eg of the order of 1.5eV or hydrogenated amorphous silicon cells with a band gap energy Eg of 1.7eV to 1.9eV.
- the bandgap energy of the additional module is chosen to be different from that of the additional panel and the aforementioned technologies apply in particular in the case where the existing panel uses thick mono or polycrystalline silicon cells, with a bandgap energy Eg of the order of 1.1 eV.
- the cells of the additional module are cells produced by type III-V photovoltaic technology with a band gap different from that of the cells of the existing panel.
- the cells of the module may have a higher or lower bandgap energy than that of the cells of the existing panel.
- the module comprises a conventional substrate of the glass or plastic type, which can be rigid or flexible, on which is deposited all the layers allowing the production of photovoltaic cells, these layers being structured to produce the cells and their connection tracks. .
- this assembly can be covered with an encapsulating material of the polymer type, for example Polyolefin, or of the inorganic type, for example Al2O3 and a second layer of the glass or plastic type, rigid or flexible can be laminated on the module.
- a rigid or flexible frame can be installed around the module to stiffen it or insulate it at its edges.
- the additional module 10 is advantageously fixed to the existing panel, for example a panel 100 by means of a transparent adhesive or encapsulating material 19.
- a material transparent to the operating wavelengths of the panel deducted from the spectral range absorbed by the additional module, for example between 700 and 1200 nm at a minimum, whose refractive index will minimize reflections at the interfaces between the module and the existing panel, can be used to make the junction between the existing panel and the additional module in order to allow irradiation of the existing panel.
- the additional module is configured to present at its output terminals a voltage V1 close to the voltage VMPP of the existing panel in operation when the latter is combined with the additional module.
- the voltage V1 is chosen as being at least the voltage VMPP ⁇ 10% which constitutes an acceptable error.
- the existing panel is a panel of known type, in particular with monocrystalline or polycrystalline silicon cells.
- the existing panel 100 can for example be of the traditional full cell type with rows 101, 102, 103, 104, 105, 106 of cells 150 in series, the rows themselves being connected in series by links 110, 120.
- the panel further comprises shunt diodes 131, 132, 133 called bypass in English which will inhibit the shaded panel parts.
- the panel 200 is of the half-cell 250 type with two banks of secondary networks of half-cells 200a, 200b connected in series by links 220a, 220b, 210 and in parallel by connections 115.
- the panel also comprises in this case three bypass diodes 231, 232, 233.
- the panel 300 is of the type with tiled cells 350 (shingle cell in English) and comprises a first half-panel 301 comprising strips 301 a, ..., 301 f of cells in series these strips being connected in parallel and a second half-panel comprising strips of cells in series 302a, ..., 302f themselves connected in parallel.
- the strips of the sub-panels 301, 302 are connected in series by links 310 and in parallel by links 315, 325. In the latter case two bypass diodes 331, 332 are provided.
- the existing panel can be single-sided to transform light arriving on one side or double-sided, i.e. adapted to transform light arriving on both sides.
- the voltage VMPP of the panel is the sum of the voltages VMPPC of the unit cells, 72 cells according to the example, and the current is the current passing through each of the cells in the absence of shading.
- the voltage is the sum of the voltages of half the cells of the panel, ie the voltage of 2 ⁇ 36 cells according to the example, and the current is the sum of the currents of the half-panels.
- the panel output voltage is the sum of the voltages of the cell elements succeeding one another in a strip along the length of the panel, 72 elements according to the example, and the current is the sum of the currents of the strips in parallel across the width of the panel.
- the existing panel as comprising a major network REI supplying the voltage and the output current of the panel and possibly minor networks RE2 the networks put in parallel in the existing panel if necessary.
- the additional module according to the examples shown will be made up from a minor network of cells formed as a strip of length Lceii and height Hceii put in series to reach the voltage V1 equal to VMPP of the existing panel to within 10% .
- FIG. 6 illustrates the optimization process which includes the determination in step 1 of an operating voltage VMPP of an existing panel with P cells of a first type, for example cells based on crystalline silicon , the production in step 2 of an additional module 10 comprising a second plurality Q of cells of the second type and with a band gap different from the cells of the existing panel configured to supply an operating voltage V1 equal to within ⁇ 10% to the voltage VMPP of said panel or of said group of existing panels, the installation in step 3 of the additional module overlapping on or under the existing panel, the module being connected in parallel to said existing panel or to said group of existing panels.
- the starting point is the width I and the length L of the panel and it is chosen whether the plurality Q of cells is arranged parallel to the length L of the existing panel or to its width.
- Step 21 determines the maximum power point voltage VMPP of the existing panel combined with the additional module
- step 22 the number N of cells to be put in series is calculated to produce a sub-module S1 of the additional module adapted to supply said voltage V1.
- step 23 a height Hceii of said cells of the sub-module S1 is calculated and in step 24 the number M1 of sub-modules S1 that can be implanted in parallel over the width I of the existing panel is calculated, maximizing the power of said module covering the existing panel at voltage V1. It should be noted that steps 23 and 24 are interdependent. Several combinations can exist but we choose the one that allows to deliver a maximum of power.
- step 25 the additional module is produced in structurable photovoltaic technology comprising M1 under modules S1 in parallel, encapsulation of the additional module and installation of the additional module overlaying the existing panel.
- the resulting additional module is shown schematically in Figure 4 with the minor networks 10a, 10b, 10c, 10d each comprising 46 cells of length Lceii and cell height Hceii of 4.91 mm to supply a voltage V1 equal to VMPP at 0.2 % close, these minor networks being placed in parallel by links 15 and 16 to produce the module of width adapted to the existing panel.
- the losses at the complementary module level are 0.1 W which is very low compared to a panel with cells of optimal dimensions above.
- the spatial organization of the existing panel according to Figure 1 is an organization where the cells are connected in series on lines and connected in Zig-Zag line by line on the height of the panel while the spatial organization of the additional module comprises on the height of the panel four strips of cells connected in parallel, the strips of cells being made up of cells connected in series along a direction parallel to the height of the panel.
- the two panels thus have different spatial and electrical organizations.
- the additional module will be configured on demand according to the type of existing panel to be renovated.
- the 47 cells in strip height 4.32 mm and of length equivalent to the length of the panel in series form a sub-network or minor network S1, four minor networks being connected in parallel to form a major network.
- the existing panel comprises 6 minor arrays of cells in series, each minor array comprising two superimposed half lines of cells in series, the minor arrays are two by two in parallel along the length of the panel then connected in series. along the width of the panel to form the major array of the existing panel while the add-on still has four cell strips connected in parallel across the height of the panel, the cell strips being made up of cells connected in series along a direction parallel to the panel height.
- the spatial organization and the electrical organization of the two panels is again different.
- the module is structured on demand according to the configuration of the existing panel, it is possible to organize the complementary module with strips of cells extending over the width of the panel in series along the length of the panel, these strips being placed in parallel one after the other along the length of the panel. This allows for example to orient the cells of the additional module
- FIGS. 5A to 5D a configuration with an additional module 10 Perovskite, of 300 W of power, represented in FIG. 5A with four subnets 10a, 10b, 10c, 10d in parallel.
- This additional module is placed on the existing panel on the illuminated side of the existing panel and connected in parallel to this panel.
- the existing panel used is a full cell PERC silicon panel rated at 300W.
- Such a panel whose configuration is as described in Figure 1 is provided with six rows 101, 102, 103, 104, 105, 106 of cells in series and three bypass diodes 131, 132, 133. It delivers about 160W when under the additional module.
- the panel 100 then sees all of its cells of the lines 101 and 102 deactivated and the diode 133 becomes conductive which causes a loss of 1/3 of its power.
- the additional module loses little power and overall the balance is favourable. It is the same for the cases of Figures 5C, shading 21 of the upper half of the assembly and Figure 5D shading 22 of a side half.
- FIGS 9A to 9C give examples of possible configurations within the scope of the invention.
- each existing panel 100a, 100b is connected in parallel to an additional module 51 and these individually optimized panels are connected in series by a link 61 and connected to other panels by the serial link 60a, 60b.
- additional panels 52a, 52b are positioned on panels 100c, 100d of a group of panels 100c, 100d, and connected in parallel to these panels 100c, 100d by links 63a, 63b, 65a, 65b, the panels 100c, 100d being for their part connected in series by a link 64.
- the voltage V1 of the modules must be the voltage 2XVMPP sum of the VMPPs of each panel of the group.
- each panel 100e, 10Of of a group of two panels receives an additional module 53a, 53b.
- the existing panels are connected in series by a link 68
- the modules 53a, 53b are connected in series by a link 67
- the pair of existing panels 100e, 10Of are connected in parallel to the pair of complementary panel modules 53a, 53b.
- the voltages V1 of each module 53a, 53b must be established so that the voltage of all the additional panels connected in series corresponds to the voltage of all the existing panels put in series. This can be generalized to a complete line of existing panels managed by a voltage converter.
- the number of panels of the groups of panels may be different from two while remaining within the scope of the invention. It is thus possible within the framework of the invention to add the additional modules to the existing panels of a group of panels and to connect these modules in series with each other and in parallel with all the panels themselves. Same connected in series as shown in Figure 9C for two existing panels and two additional modules. This can be useful if, for example, it is desired to alleviate localized shading phenomena on a photovoltaic park or to reduce the costs of updating the park.
- the additional module 10 is placed overlapping the existing tiled cell panel 300 and connected in parallel with the latter to produce a common voltage output 17, 18.
- the voltage V1 of the additional module will be calculated by taking as value of VMPP the sum of the voltages VMPP of the panels in series and the module will be structured accordingly.
- the additional module uses structured thin layer technology
- the latter can be produced in one piece by depositing and structuring the layers constituting the strips forming the cells and the tracks directly on a single substrate, for example by laser structuring.
- the invention is not limited to the examples described above, but it encompasses all the variants that a person skilled in the art may consider in the context of the protection sought.
- the technology of Additional module cells may differ from thin film technology.
- the orientation of the strips constituting the cells of the additional module can be parallel to the length or the width of the existing panel(s) and the surface covered by this module can be adapted to optimize the number parallel minor networks.
- the forbidden band of the cells of the additional module can be chosen to allow a range of wavelengths to pass through these cells adapted to maximize the efficiency of the cells of the existing panel under the additional module.
