Description
Technical Field
The invention relates to the technical field of photovoltaics, in particular to a photovoltaic module cleaning and cooling device.
Background
When the energy reaching the ground every second reaches 80 ten thousand kilowatts, if 0.1% of the solar energy on the earth surface is converted into electric energy, the conversion rate is 5%, the annual generating capacity can reach 5.6 × 1012 kilowatt hours, which is equal to 40 times of the energy consumption in the world, and due to the unique advantages of the solar energy, after the 80 th century, the types of the solar cells are continuously increased, the application range is increasingly wide, and the market scale is gradually enlarged.
However, the power generation efficiency of the photovoltaic power station system is the most concerned problem of market investors, and factors influencing the power generation of the photovoltaic power station system are still more. This requires investors to make decisions after learning and understanding carefully before investing and considering the local geographical climate, which are the main factors affecting the power generation of the photovoltaic power station system? The method mainly comprises the following points:
solar radiation amount, solar module inclination angle, solar cell conversion efficiency, combination loss, dust blocking, temperature characteristics, direct current line loss, alternating current line and transformer loss, inverter efficiency and MPPT deviation, shadow and snow blocking, and the like. The image radiation amount is an uncontrollable factor, but can be evaluated according to the illumination radiation amount counted in the local calendar year, the conversion rate and attenuation loss of components, the line loss and the conversion rate of an inverter are extremely developed at present, and the method cannot revolutionarily break through in a short term! Therefore, the specific influence of the two factors on the power generation of the photovoltaic power station system can be known firstly from the idea that the space which cannot be optimized can be seen only from the dust shielding and the temperature characteristic of the component. Regarding the conversion efficiency of the solar panel, it is noted that the temperature of the battery cells (power generating elements) on the panel affects the power generation efficiency. Especially in panels using crystalline silicon based cells, the temperature rise can lead to a significant reduction in conversion efficiency. The conversion efficiency of a solar panel is usually a value measured when the temperature of a cell is 25 ℃, but when the temperature of a cell reaches 25 ℃, the ambient temperature tends to be 20 ℃ to 30 ℃ lower than that, and in most regions, the conversion efficiency indicated in the product catalog is difficult to achieve unless in winter. This often causes the generation amount to be rather lower than that in spring and autumn when the radiation amount is the largest in summer.
It is also widely accepted in the photovoltaic industry that dust is the first killer to affect the overall power generation capacity of a photovoltaic power plant. The light reaching the surface of the component is shielded to influence the generating capacity and the normal heat dissipation thereof, so that the photoelectric conversion efficiency is influenced; some dust has acid-base characteristics, is deposited on the glass surface of a certain specific area of the assembly for a long time, can corrode the assembly and cause further accumulation of the dust in the area, thereby not only shielding seriously and increasing the diffuse reflection of sunlight, but also leading the temperature of a spot area to rise linearly and be far higher than the temperature of a peripheral area, and seriously causing the hot spot effect of the assembly so as to greatly reduce the power generation efficiency of the assembly!
Photovoltaic power generation users in some remote areas can take advantage of the fact that the users can take the photovoltaic power stations once and for all after mistakenly assembling the photovoltaic power stations. Consequently, the energy generation is reduced in a period of time, and the difference from the expected value is very far. The dust removal of photovoltaic power stations is seemingly simple, but in a small amount! Whether the dust removal science directly relates to the generated energy, the service life and the income of a power station or not, the generated energy of the power station is required to be kept stable, the service life is long, the income is stable, and the follow-up maintenance of the photovoltaic is indispensable!
The main means for cleaning the photovoltaic power station at the present stage are as follows: the photovoltaic power station is treated by three modes of a cleaning vehicle, manual cleaning and a cleaning robot, and the phenomenon that the operation and maintenance of the photovoltaic power station are carried out, namely, the phenomenon that fish is beaten for three days and the net is dried for two days is more. The cleaning frequency is increased along with the change of the weather, such as snowstorm weather, spring sand and dust weather, and the like under the condition of 2-3 times per month in general; and the cleaning frequency can be reduced in rainy season.
