Background

A large number of photovoltaic modules are the basic components of a photovoltaic power plant. Factors affecting the photovoltaic power generation efficiency are important parts for the operation and maintenance of the photovoltaic module besides the technical and natural environment of the battery. For a photovoltaic power station which is built and put into operation, the operation and maintenance of the power station are the basis of the efficient and safe operation of the power station. In order to ensure the system efficiency of the photovoltaic power station and improve the power generation capacity of the power station, the cleaning work of photovoltaic power station components is particularly important.

Conventional cleaning can be divided into general sweeping and rinsing cleaning.

In the ordinary cleaning, a dry small broom or a rag is used for sweeping off attachments such as dry floating ash, leaves and the like on the surface of the component. For hard foreign matters such as mud, bird droppings and sticky objects which are tightly attached to the glass, a slightly hard scraper or gauze can be used for scraping, but care needs to be taken that the hard materials cannot be used for scraping so as to prevent the surface of the glass from being damaged. Whether to perform rinsing cleaning is considered in terms of sweeping effect.

Washing and cleaning are required for objects which cannot be cleaned by colored substances such as bird droppings, plant juice and the like or wet soil and the like, which are tightly adhered to glass. The cleaning process generally uses clear water, and the clear water is matched with a flexible brush to remove. When oily dirt is encountered, the polluted area can be cleaned separately by using liquid detergent, soapy water and the like.

Because the long-term calcified deposits are continuously generated in the use process of the photovoltaic module, if the photovoltaic module is not cleaned in time, local shading can be caused, the shading diameter exceeds 1cm or the power of the photovoltaic module is influenced by uneven shading objects and exceeds 15 percent, the phenomenon of hot spots is easy to occur, and the irreversible attenuation of the photovoltaic module is easy to cause, so that the photovoltaic module needs to be cleaned for a plurality of times at regular time to ensure that the surface of the photovoltaic module is not shaded. The conventional cleaning needs a large amount of water source supply, frequent cleaning operation easily causes water resource loss and waste, and when the water source cannot be provided in a drought area, the cleaning operation wastes time and labor, and the cleaning effect is poor.

The vertical water pipe is fixed by a tripod bracket 61 to prevent the spray head from splashing due to overlarge pressure, and is placed below the front row group at a distance of 30-50cm from the assembly. The vertical parts of the water supply pipes 6 are all butted by adopting a movable wire, so that the water supply pipes are convenient to disassemble. The bent part of the water supply pipe 6 is connected with the rotary nozzle 5 by a movable wire, so that the disassembly is convenient.

When raining, rainwater can be collected through the first water collecting groove 2 and the second water collecting groove 4. The vent hole 33 prevents water collection from being blocked due to air pressure rushing to the top, and the water level can be tested through the vent hole 33. The spraying system is mostly started in the morning and evening, and the dust adhesion is reduced by flushing when moisture condensation water is not dry at night. Rainwater, dew and flushing water are collected and gathered to the underground water storage device when flowing down along the photovoltaic module, and are recycled through the spraying device after being precipitated.

It should be noted that:

(1) the power generation loss of the photovoltaic array and even the hot spot effect caused by artificial shadow in the cleaning process are prevented;

(2) the surface temperature of the component is quite high in noon or better in illumination, so that the glass or the component is prevented from being damaged due to cold water shock on the surface of the glass;

(3) in order to ensure the safety of cleaning personnel, the cleaning is carried out in a time period with dim sunlight in the morning and at night, so that the potential safety hazard is reduced. It is also contemplated that the cleaning may be performed in a rainy day, where the cleaning process may be relatively efficient and thorough due to the assistance of precipitation.

It will be appreciated by those skilled in the art that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The embodiments disclosed above are therefore to be considered in all respects as illustrative and not restrictive. All changes which come within the scope of the invention or which are equivalent to the scope of the invention are embraced by the invention.
