Industry Background and Demand Characteristics

China's photovoltaic industry started in the European market demand around 2005, more than ten years to achieve from scratch, from there to strong leap-forward development. According to the statistics of the National Energy Administration, since 2013, China's photovoltaic power generation has grown rapidly, as of the first half of 2021, the cumulative installed capacity of photovoltaic power generation in the country is 267.08GW, of which 13.01GW of new installed capacity, an increase of 12.93%. The continuous increase in installed capacity has brought huge power generation, but also brought a lot of maintenance costs.

The basic photovoltaic power generation panel has weak anti-pollution ability and is easy to reduce power generation efficiency due to surface contamination. Once the large particles of dust on the photovoltaic panels are deposited, the efficiency of receiving sunlight radiation will be reduced by 11-15%, and the power generation potential will be reduced by an average of 13%. Most of the solar photovoltaic power generation base stations are built in the suburbs, dust and sand are common, and natural pollution of power generation panels cannot be avoided. In the context of a large number of installed machines, the problem of widespread panel pollution and reduced efficiency is easy to lead to a huge loss of power generation. Therefore, in order to maintain the ideal power generation, it is necessary to ensure that the power generation panel is clean. At the same time, if the light conversion rate can be increased and the power generation efficiency can be improved, the efficiency decline caused by reasonable pollution and depreciation can also be covered to a certain extent.

Industry Pain Point

Because photovoltaic power generation base stations are usually built in areas with strong sunlight exposure away from the city, and the larger the base station, the more remote, the more inaccessible, the worse the natural conditions, generally high altitude, the Gobi desert and other places. If the photovoltaic power generation panel relies on manual cleaning, there is a great inconvenience. If the use of high-pressure water cleaning, robot cleaning, etc., will cause wear on the surface of the power generation panel light transmission coating, so that the light transmission attenuation is accelerated, shorten the life of the panel. Therefore, the power generation panel urgently needs to achieve anti-fouling, self-cleaning functions and improve power generation efficiency as much as possible.

Solution

Titanian Technology has developed a series of self-cleaning coatings specially used for the self-cleaning function of the surface of the object, among which, in view of the needs of the self-cleaning of the surface of the photovoltaic power generation panel, the photovoltaic panel dustproof self-cleaning hydrophobic coating and photovoltaic panel to improve the power generation nano self-cleaning coating have been developed to meet the requirements of photovoltaic power generation panel self-cleaning and increase the power generation. Photovoltaic panel dust-proof self-cleaning hydrophobic coating, photovoltaic panel to improve power generation nano self-cleaning coating are single-component polymer coating, mainly composed of inorganic oxides and fluorosilicone resin through scientific matching and modification, forming micro and nano hydrophobic structure, with excellent self-cleaning performance, and can adjust the transmittance of different bands of light, enhance the effective photoelectric conversion band anti-reflection effect. Improve the conversion of photovoltaic modules to light, thereby improving the efficiency of power generation.
