Description

Technical Field

[0001] This invention relates to the field of photovoltaic operation and maintenance materials technology, and in particular to a biodegradable, high-efficiency, and clean material for photovoltaic modules and its preparation method. Background Technology

[0002] With the large-scale popularization of photovoltaic power plants, dust pollution on the surface of modules has become a core issue restricting power generation efficiency. In outdoor environments, dust, bird droppings, oil stains, and mud will continuously adhere to the surface of the modules. Actual measurements show that severe dust accumulation can reduce power generation efficiency by 20%-30%, directly reducing the revenue of the power plant.

[0003] Currently, the industry lacks dedicated, environmentally friendly, and safe cleaning materials. Mainstream cleaning methods either use ordinary water, which has weak cleaning power and cannot remove stubborn stains; or use industrial cleaning agents, most of which contain non-degradable petrochemical components, strong acids, and alkalis, polluting soil and water sources and corroding the anti-reflective coating, tempered glass, and encapsulating adhesive layers on the module surface, shortening the module's lifespan. Manual cleaning is not only inefficient and costly, but also poses safety risks due to high-altitude operations in rooftop distributed systems. Existing cleaning materials generally fail to meet the three core requirements of efficient decontamination, environmental degradability, and module safety protection, becoming a key bottleneck for the intelligent and green development of photovoltaic operation and maintenance. They also cannot meet the large-scale operation requirements of AI cleaning robots. Therefore, to solve these problems, a dedicated biodegradable and efficient cleaning material for photovoltaic modules and its preparation method are proposed. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a biodegradable and highly efficient cleaning material for photovoltaic modules and its preparation method.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] According to the mass fractions, the first component comprises: 3-8 parts sodium alkanolamide polyether sulfate, 6-15 parts potassium cocoyl glycinate, 1-3.5 parts sodium bicarbonate, 0.3-0.45 parts sodium chloride, 2-3.8 parts sodium carbonate, 5-7.5 parts fatty alcohol polyoxyethylene ether, 2-2.8 parts alkyl glycoside, 1.8-2.2 parts sodium citrate, 2-3 parts glycerin, and 4.5-5 parts phenoxyethanol;

[0008] According to the mass fractions, the second component includes: 88-95 parts of deionized water.

[0009] Preferably, by mass fraction, there are 6 parts of sodium alkanolamide polyether sulfate, 8 parts of potassium cocoyl glycinate, 2.5 parts of sodium bicarbonate, 0.35 parts of sodium chloride, 3.2 parts of sodium carbonate, 6.6 parts of fatty alcohol polyoxyethylene ether, 2.6 parts of alkyl glycoside; 2 parts of sodium citrate, 2.4 parts of glycerol, 4.8 parts of phenoxyethanol, and 90 parts of deionized water.

[0010] Preferably, the combination of sodium alkanolamide polyether sulfate and potassium cocoyl glycinate can synergistically improve foam stability and oil stain encapsulation ability, thereby reducing the amount of cleaning materials used.

[0011] Preferably, both the fatty alcohol polyoxyethylene ether and the alkyl glycoside are biodegradable nonionic surfactants with high biodegradability in natural environments and no residual pollution.

[0012] Preferably, the glycerin acts as a humectant, which can slow down the drying speed of the cleaning solution, prevent stains from drying and forming water stains, and ensure the smoothness of the component surface after cleaning.

[0013] Preferably, the phenoxyethanol is a mild preservative that can extend the product shelf life to more than 12 months, and does not react with the component material or damage the power generation performance.

[0014] A method for preparing a biodegradable and highly efficient clean material specifically for photovoltaic modules, the method comprising the following steps:

[0015] S1: Raw material preparation: Take 6 parts of sodium alkanolamide polyether sulfate, 8 parts of potassium cocoyl glycinate, 2.5 parts of sodium bicarbonate, 0.35 parts of sodium chloride, 3.2 parts of sodium carbonate, 6.6 parts of fatty alcohol polyoxyethylene ether, 2.6 parts of alkyl glycoside; 2 parts of sodium citrate, 2.4 parts of glycerol, 4.8 parts of phenoxyethanol, and 90 parts of deionized water.

[0016] S2: Deionized water treatment. Add deionized water raw material to the mixing tank and start low-speed mixing.

[0017] S3: Add alkaline raw materials, add sodium carbonate, sodium bicarbonate, sodium citrate, and sodium alkanolamide polyether sulfate to the deionized water in the mixing tank in step two in sequence;

[0018] S4: Add organic additives, add glycerin to step three;

[0019] S5: Add surfactant, add potassium cocoyl glycinate to step four;

[0020] S6: Add functional additives, add sodium chloride to step five;

[0021] S7: Add other raw materials, add fatty alcohol polyoxyethylene ether, alkyl glycoside and phenoxyethanol to step six in sequence;

[0022] S8: Detection, the pH value of the mixture in step seven is detected;

[0023] S9: Finished product, which is the filtered and bottled mixture after testing.

[0024] Preferably, the stirring speed of S2 is 30-60 r / min and the stirring time is 5-10 minutes, so that the deionized water forms a uniform flow field and provides a stable environment for the subsequent dissolution of raw materials.

[0025] Preferably, the alkaline raw materials in S3 are added at intervals of 3-5 minutes, and after all are added, the mixture is stirred continuously for 10-15 minutes to ensure that the solid raw materials are completely dissolved without any precipitation.

[0026] Preferably, the pH value of the mixture in S8 needs to be controlled in the weakly alkaline range of 7.5-8.5 to avoid strong acids and alkalis corroding the coating on the surface of the photovoltaic module and the tempered glass.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] 1. This invention uses biodegradable and mild raw material formulas throughout the process. The core surfactants are natural derivatives such as fatty alcohol polyoxyethylene ethers and alkyl glycosides, which have a high biodegradability rate. The waste liquid after use can decompose naturally and will not pollute the soil or water sources, fully complying with environmental protection policy requirements. The product's pH value is precisely controlled in the weakly alkaline range of 7.5-8.5. It does not contain strong acids, strong alkalis, fluorescent agents, phosphides, or other harmful substances. It will not corrode the tempered glass, anti-reflective film, and encapsulation layer of photovoltaic modules during cleaning. Long-term use will not cause problems such as whitening, scratches, or coating peeling. Compared with traditional industrial cleaning agents, it improves the protection rate of modules, effectively extends the service life of photovoltaic modules, reduces the replacement and maintenance costs of power stations, and meets the green operation and maintenance requirements of distributed and centralized photovoltaic power stations.

[0029] 2. This invention achieves highly efficient cleaning through the synergistic effect of a multi-component formula. The combination of anionic and nonionic surfactants quickly adsorbs and encapsulates stubborn stains such as dust, oil, and bird droppings. Alkaline raw materials soften water and decompose stains, allowing them to be quickly peeled off from the module surface. In actual use, the dust removal rate is improved, and the cleaning time is reduced by half compared to traditional methods. Combined with an AI cleaning robot, it can achieve integrated cleaning and inspection operations, improving overall cleaning efficiency. After cleaning, the light transmittance of the modules is significantly restored, increasing the power generation per watt and directly increasing the power plant's revenue. This solves the pain points of incomplete, inefficient, and costly manual cleaning, perfectly meeting the needs of intelligent upgrades in photovoltaic operation and maintenance.

[0030] 3. The formula in this invention is scientifically sound and the raw materials are all readily available conventional chemical raw materials on the market, ensuring a stable supply chain and lower procurement costs compared to imported photovoltaic cleaning agents. The preparation process uses ambient temperature and pressure stirring, eliminating the need for high-temperature and high-pressure equipment, resulting in low energy consumption, simple operation, and high production efficiency, making it suitable for large-scale factory production. The product has extremely strong adaptability, suitable for residential distributed photovoltaic, commercial and industrial rooftop photovoltaic, and large-scale ground-mounted centralized power stations. It can be used in conjunction with AI cleaning robots, high-pressure spraying, manual wiping, and other methods. No professional skills are required for use, storage and transportation are convenient, and the shelf life is long. It can effectively reduce the operation and maintenance costs of photovoltaic power stations, solve industry operation and maintenance problems, and promote the transformation of the entire photovoltaic operation and maintenance industry towards low cost, high efficiency, and intelligence.

[0050] S8: Detection, the pH value of the mixture in step seven is detected;

[0051] S9: Finished product, which is the filtered and bottled mixture after testing.

[0052] As a technical optimization of the present invention, the stirring speed in S2 is 30-60 r / min and the stirring time is 5-10 minutes, so that the deionized water forms a uniform flow field and provides a stable environment for the subsequent dissolution of raw materials.

[0053] As a technical optimization of the present invention, the alkaline raw materials in S3 are added at intervals of 3-5 minutes, and after all are added, the mixture is stirred continuously for 10-15 minutes to ensure that the solid raw materials are completely dissolved without precipitation.

[0054] As a technical optimization of the present invention, the pH value of the mixed solution in S8 needs to be controlled in the weakly alkaline range of 7.5-8.5 to avoid strong acid and strong alkali corroding the surface coating and tempered glass of the photovoltaic module.

[0055] When in use, the photovoltaic module-specific biodegradable and highly efficient cleaning material of this invention consists of two main parts: a cleaning agent and a solvent. The overall design revolves around three core objectives: "highly efficient cleaning, safe panel protection, and environmentally friendly biodegradability." It uses more than ten kinds of raw materials compounded in a specific ratio to form a synergistic system. Each component has a clear function, and they work together without conflicting with each other, ultimately achieving safe, efficient, and environmentally friendly cleaning of photovoltaic modules.

[0056] The solvent portion uses deionized water, comprising 88-95 parts, serving as the carrier and the most basic dispersion medium for the entire cleaning material. This deionized water undergoes purification treatment to remove all metal ions and impurities such as calcium, magnesium, iron, and manganese. If these ions remain in the water, they will form scale, white spots, and water stains on the component surface during cleaning, affecting light transmittance. Using deionized water as a carrier ensures uniform flow and easy spraying of the cleaning solution, while preventing scale residue and leaving the cleaned component surface bright and clean. Simultaneously, deionized water is chemically stable and will not react with any components in the cleaning agent, allowing the effective ingredients to fully exert their properties. It also reduces the viscosity of the cleaning solution, making it compatible with the spray system and wiping rollers of AI cleaning robots, achieving uniform coverage without leaving any blind spots.

[0057] The cleaning agent is the core functional component, precisely formulated from a variety of ingredients, each with its specific function. Sodium alkanolamide polyether sulfate, comprising 3-8 parts, is an anionic surfactant and one of the main cleaning agents. Its molecule has a hydrophilic end and an oleophilic end. The oleophilic end firmly grasps organic dirt such as oil, bird droppings, and dust on the component surface, while the hydrophilic end binds to water molecules, encapsulating the dirt and allowing it to detach from the glass surface and disperse into the water. It also has excellent resistance to hard water; even in areas with hard water, it will not fail or produce sediment, ensuring its usability in power plants across the country.

[0058] Potassium cocoyl glycinate, at 6-15 parts, is a mild amino acid-based surfactant. When used in combination with sodium alkanolamide polyether sulfate, it achieves a synergistic effect greater than the sum of its parts. Made from natural coconut oil, it is very mild, biodegradable, and environmentally friendly. Its strong penetrating power allows it to reach even the smallest crevices in stains, loosening and softening stubborn dirt while producing fine, stable foam. This allows the cleaning solution to remain on the component surface longer, preventing it from running off quickly and extending the cleaning time. Being weakly alkaline, it helps regulate the overall pH, preventing the product from becoming too acidic or too alkaline and protecting the components from corrosion.

[0059] Sodium carbonate, sodium bicarbonate, and sodium citrate work synergistically, comprising 2-3.8 parts, 1-3.5 parts, and 1.8-2.2 parts, respectively. Sodium carbonate and sodium bicarbonate act as alkaline buffers, softening water, breaking down acidic stains and grease, and enhancing cleaning power. Sodium citrate acts as a chelating agent, binding residual metal ions in the water to prevent scale formation and stabilizing the alkaline components, preventing the cleaning solution from separating or settling. The combination of these three ingredients maintains a stable pH value between 7.5 and 8.5, a range that ensures efficient cleaning while remaining absolutely safe, without damaging the anti-reflective coating or glass of the components.

[0060] Sodium chloride is added in small amounts (0.3-0.45 parts), but its effect is crucial. It thickens the cleaning solution, allowing the liquid to adhere better to the component surface and preventing rapid runoff; it also enhances the adsorption capacity of surfactants, making the foam more stable and less prone to breaking during cleaning; at the same time, it improves the product's storage stability, preventing it from separating or deteriorating over time, and adding a small amount has no impact on environmental protection and degradation performance.

[0061] Fatty alcohol polyoxyethylene ethers and alkyl glycosides are nonionic surfactants, comprising 5-7.5 parts and 2-2.8 parts respectively, and are the core components for achieving biodegradability. Fatty alcohol polyoxyethylene ethers have extremely strong penetrating power, quickly reducing the surface tension of water, penetrating the interface between stains and glass, lifting the stains for easy removal; alkyl glycosides, synthesized from glucose and fatty alcohols, are non-toxic and harmless, with a high degradation rate, completely decomposing in the natural environment after use, leaving no residue or pollution. The combination of these two enhances cleaning power while ensuring environmental friendliness, solving the problem of environmental pollution caused by traditional cleaning agents.

[0062] Glycerin, comprising 2-3 parts, acts as a moisturizing lubricant. During cleaning, it forms a very thin film of water on the glass surface, preventing the cleaning solution from drying too quickly and avoiding stains from hardening and leaving marks. It also lubricates the AI ​​robot's cleaning cloth, reducing friction between the cloth and the glass and preventing scratches on components. Additionally, glycerin has antifreeze properties, preventing the cleaning solution from freezing in low winter temperatures, making it suitable for use in both northern and southern regions.

[0063] Phenoxyethanol, at 4.5-5 parts, is a mild preservative. It inhibits the growth of bacteria and mold, extending the product's shelf life to over 12 months, preventing mold growth and spoilage over extended periods. It has very low toxicity, does not irritate component materials, evaporates quickly after cleaning without leaving residue on the glass, and does not affect light transmission or power generation.

[0064] In actual operation, the cleaning solution is sprayed onto the module surface. The surfactants first adsorb and penetrate the stains, the alkaline components decompose stubborn dirt, and the humectant prevents drying. After standing for 1-2 minutes, the stains are wiped off with the cleaning solution or rinsed with water, and the module surface is immediately clean again. The entire process does not damage the modules, leaves no residue, and the waste liquid is biodegradable, truly achieving high efficiency, safety, and environmental protection, and fully meeting the needs of intelligent operation and maintenance of photovoltaic systems.

[0065] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
