UTILITY MODEL DESCRIPTION

DESCRIPTION of the utility model entitled "Integrated cleaning and cooling system for photovoltaic panels"

TEXT OF THE DESCRIPTION

The "integrated cleaning and cooling system for photovoltaic panels" whose structure and purpose are about to be described, can be applied to any type of panel and surface.

However, for purely elaborative needs, we want to proceed with the description of the structure applied to a corrugated sheet (Table I, letter L; Table II, letter A; Table III, letter A) of standard dimensions (5.494mm x 500mm) on which a carpet of amorphous silicon is glued (Tav I, lett. I; Tav. Π, lett. B; Tav. III, lett. E).

The structure of the integrated cleaning system is as follows:

- the main water supply pipe has a diameter of 3/8 and is positioned under the upper part of the sheet (Table I, letter A).

The same is interrupted by 3/8 inch x 2 1⁄4 inch T-fittings (Table I, letter E).

- The descending tube from the main one, whose dimensions are 1⁄4 inch (Table I, letter M; Table III, letter B), runs along the curvature of the corrugated sheet {Table I, letter L ; Table Il, lett. TO; Table III, lett. A) and, in turn, is interrupted by n. 6 T joints of equivalent diameter (Table I, letter F; Table III, letter C) and ends with an L joint having the same size (Table I, letter H).

- All the fittings and the elbow have a threaded nozzle at their ends that comes out of the sheet (Table I, letter G; Table II, letter C; Table, III, letter D).

The aforementioned nozzles nebulize a directed cutting water jet on the carpet (Table I, letter H; Table III, letter F) ensuring the cleaning and cooling of its entire surface (Table I, letter I ; Table II, letter B; Table III, letter E).

The nozzles necessary to ensure the achievement of this purpose are n. 7 positioned, excluding those placed at the ends, with a distance between centers of 914 mm (Table II).

- A pump is positioned at the end of the delivery pipe, with an expansion lung, of variable power depending on the total surface to be treated (Table I, letter D). The pump comes into operation by sending the entire system under pressure, taking water from a storage tank with the maximum capacity to allow an entire cycle (Table I, letter C).

- Upstream of the storage tank, a diversified water purification and desalination apparatus must be applied according to the environmental situation and the organoleptic composition of the water, such as a filtering cartridge (Table I, lett. B), an osmotizer or a softener (Table IV, lett. A).

- An infuser of cleaning chemicals (Table IV, letter B) controlled by a control unit can be applied to the storage tank, according to specific needs (Table I, letter N).

- The entire system is activated and controlled by the aforementioned electronic control unit and by some solenoid valves (Table I, letter O). The first, duly programmed, regulates and monitors both the quantity of water used and the number of washing and cooling cycles.

- At the end of each cycle, the entire hydraulic system empties completely, thus avoiding the formation of scale and scale.

The purposes and benefits of the "integrated ptiHzia and cooling system for photovoltaic panels" consist of:

1) guarantee a better cleaning and cooling system of the panels as it works in all weather conditions as it is not dependent on mechanical and / or electrical devices subject to wear, freezing and seizures;

2) ensure control of the maximum operating temperature of the panels by planning the cooling cycles;

3) better exploitation of resources such as the considerable decrease in water use;

4) reduction of the number of maintenance interventions and, consequently, of the expenses connected to them, as there are no moving mechanisms;

5) present advantages in terms of cost-effectiveness in the construction and sales phase due to its components;

6) do not request the disposal of excess water as it is nebulized;

7) possibility, through automatic selection made by the control unit, of differentiated use: hot water for cleaning and cold water for cooling.

What has just been specified is realized in the hypothesis in which the cleaning system is applied to sanitary water production plants;

8) high adaptability to every need: by controlling the control unit you can program the number of cycles and the amount of water used, as well as the addition of chemicals

9) as an option, a chemical dispenser can be applied to the water storage tank to deal with situations of particular need for cleaning (e.g. installation of the system in areas particularly exposed to polluting atmospheric agents, such as smog, bird droppings , proximity to chimneys or vents of production or industrial plants in general);

10) lower environmental impact since, being inserted into the support structure of the panels, no part of it is visible except the nozzles that protrude from it for a few centimeters;

with regard to amorphous silicon panels, having the further characteristic of being flexible to allow optimal architectural integration in compliance with particular landscape requirements, it allows to blend within the structure, enhancing its functionality.

Claims (2)

CLAIMS Paragraph 1 - Independent claim 1 The integrated cleaning and cooling system for photovoltaic panels takes its cue from already patented systems, such as "light wash" and "solar wash". Unlike the latter, the integrated system does not require moving mechanisms and is not limited to exercising its function through the mere flow of water that comes out of a single point at the upper end of the panels themselves. In fact it is characterized by the fact that it is incorporated in the same support structure of the photovoltaic panel and, therefore, camouflaged by the latter. This integrated system exploits the action of high pressure atomized water which is directed over the entire surface of the brushes by nozzles masked by the support structure. The integrated cleaning and cooling system for photovoltaic panels consists of a structured and functioning mechanism as follows: 1) main water supply pipe characterized by its interruption by T-fittings placed at equal distance and by an L-shaped connection in its final part. 2) T-shaped fittings and L-shaped fitting according to claim 1, characterized in that secondary tubes depart from each of them and thus descend from the main tube. 3) secondary pipes according to claim 2, characterized in that they are in turn interrupted by T-connectors and by an L-shaped connector in the terminal part. T-fittings and L-shaped fittings according to claim 3, characterized in that a threaded nozzle is placed at the end of each of them. 4) threaded nozzles according to claim 4 characterized by the fact that they come out of the support structure of the panels and that nebulize jets of water with a directional cut on the surface to be treated. 5) main delivery pipe according to claim 1 characterized by the presence of a filtering cartridge for water purification. 6) after the filtering cartridge according to claim 6, the system is characterized by the application of a solenoid valve which allows to use only the already treated water of the storage tank. 7) along the main delivery pipe according to claim 1 and after the solenoid valve according to claim 7, the plant is characterized by the affixing of a water storage tank, with function according to claim 7. 8) the system illustrated according to claims 1 to 8 is characterized in its terminal part by the installation of a pump with variable expansion tank. 9) the pump with expansion tank according to claim 9 is characterized by its activation by means of an electronic control unit. Paragraph 2 - Secondary independent claim The "integrated cleaning and cooling system for photovoltaic panels", object of the independent claims illustrated in the previous paragraph from point 1 to 10, can also be applied to solar panels. In fact, the use of the hot water produced by them allows them to be cleaned without causing a temporary decrease in their productivity which, on the contrary, would occur if cold water were used. This also avoids the occurrence of possible thermal shocks that could damage the constituent material of the solar panel. In this case, the mechanism is structured and functioning as already illustrated in independent claim 1, with the necessary adaptations according to the type and conformation of the solar panel to which the system itself is integrated. Paragraph 3 - Employee claim 1 In the hypothesis of particular needs deriving from environmental factors (hardness) and from the organoleptic composition of the supply water, a purification and / or desalination apparatus, such as an osmosis, can be added to the "integrated cleaning and cooling system for photovoltaic panels". liser or a softener. In this case, the aforementioned integrated system is structured and functioning as follows: 1) The system illustrated according to claims 1 to 6 of independent claim 1 described in paragraph 1, is characterized by the fact that an osmotizer or a softener is added. 2) After the osmotizer or softener according to claim 1, the system is characterized by the application of a solenoid valve, which allows to use only the already treated water of the storage tank. 3) At this point, the integrated cleaning and cooling system of the photovoltaic panels is characterized by the fact of having the same components described according to claims 8 to 10 of independent claim 1 already set out in paragraph 1. Paragraph 4 - Employee claim 2 The "integrated cleaning and cooling system for photovoltaic panels" offers the possibility to meet further needs deriving from particular unfavorable conditions. These situations occur in the hypotheses in which the installation of the photovoltaic and solar panels takes place in large urban centers where there is a high concentration of fine dust (mplO) or in places subject to problems deriving from the presence of birds. In this case, the above "integrated cleaning and cooling system for photovoltaic panels" is structured and functioning as follows: 1) The system illustrated according to claims 1 to 8 of independent claim 1 described in paragraph 1 is characterized in that a chemical additive apparatus is added. 2) At this point, the integrated cleaning and cooling system of the photovoltaic panels is characterized by the fact that it has the same components described according to claims 9 and 10 of independent claim 1 already set out in paragraph 1.
