Technical Field
The invention relates to the technical field of photovoltaics, in particular to a cleaning device for a photovoltaic panel, which is particularly suitable for water-deficient areas such as mountainous areas, deserts, high and cold areas and the like.
Background
Photovoltaic power generation is taken as one of main green energy sources and is increasingly popularized and applied, the construction quantity and scale of photovoltaic power stations are also increasingly large, and the quantity and scale of the photovoltaic power stations are gradually increased year by year on the basis of 15GW (gateway overhead ground wire) for the development of domestic annual photovoltaic power generation. The capacity of the newly built photovoltaic power station is equivalent to 300 photovoltaic power stations with 50MW every year, and the total investment exceeds billions.
Photovoltaic power stations are mostly distributed in desert regions such as Gansu, Ningxia, Qinghai and inner Mongolia in China. The problem of cleaning dust of the photovoltaic module becomes the biggest problem in maintenance of the photovoltaic power station, the dust on the photovoltaic panel directly influences the power generation efficiency of the photovoltaic module, and the problem is particularly obvious in areas with serious pollution and sand dust.
The influence of dust on the photovoltaic panel is mainly reflected in the following points:
(1) reducing the generating efficiency of the photovoltaic panel: the dust on the surface of the photovoltaic panel influences the transmittance of light, so that the solar radiation received by the surface of the component is reduced, and in parts of China, the influence of the dust on photovoltaic power generation can reach 25% at most.
(2) The dust shelters from the life that can reduce the photovoltaic board: the service life of the photovoltaic panel is 25 years. However, in the case of dust shielding, the resistance of a part of the silicon wafer is increased, and hot spots of the photovoltaic panel are formed. If the hot spots cannot be found in time in normal maintenance, the photovoltaic panel is damaged if the hot spots are light, and spontaneous combustion of the photovoltaic panel is caused if the hot spots are heavy, so that irreparable loss is caused.
At present, the current situation of cleaning and maintaining dust of domestic photovoltaic power stations is as follows:
(1) and (4) circularly cleaning by using a high-pressure water wheel and a vehicle-mounted brush. However, most photovoltaic power stations are constructed in deserts and barren mountains with serious water shortage, and the factors of peripheral terrains, natural environments and the like cause great limitations.
(2) Cleaning by manual scrubbing. However, manual cleaning has the following problems, for example: the cleaning personnel have different skills and responsibility, and the cleaning process and the quality are not easy to control; the photovoltaic panel is cleaned by trampling, so that the photovoltaic panel is seriously deformed and generates hidden cracks, and the service life of the photovoltaic panel is shortened; the consistency of manual cleaning effect is poor, hot spots are easy to generate, the power generation efficiency is influenced, and even the photovoltaic panel is damaged; the sand weather cannot be predicted, and the manual cleaning has the phenomena of lag and long period; most of the manual work is local temporary work, the manual continuity cannot be guaranteed due to the imperfect temporary labor relation, particularly in busy seasons, and the manual cleaning is more and more difficult to meet the requirements of photovoltaic power generation enterprises along with the rising of labor cost.
In conclusion, it is not difficult to find that the current domestic cleaning mode has the problems of low technical content, great defects and limitations, and great uncertainty in cleaning effect.
