Is there a market prospect for photovoltaic panel cleaning robots?
In fact, here are two questions for us?
1 Is there a prospect for the photovoltaic industry?
2 Will the photovoltaic panels be cleaned?
In fact, the logic is very simple. Whether there is a prospect is actually asking whether there is demand in the market.
An item that has no need and is not needed is definitely not needed
So this question is obviously asking whether the photovoltaic industry has prospects
At the same time, it is necessary to find out if the photovoltaic panels need to be cleaned
According to statistics, in the first half of 2020, the new installed photovoltaic power generation capacity nationwide was 11.52 million kilowatts, of which 7.082 million kilowatts were added for centralized photovoltaics and 4.435 million kilowatts for distributed photovoltaics.
Judging from the cumulative situation, as of the end of June, the cumulative installed capacity of photovoltaic power generation reached 216 million kilowatts, including 149 million kilowatts for centralized photovoltaics and 67.07 million kilowatts for distributed photovoltaics. From the perspective of the new installed capacity layout, there are more new installed capacity in North China and East China, reaching 439 and 2.19 million kilowatts respectively.
From the perspective of power generation, the national photovoltaic power generation in the first half of the year was 127.8 billion kwh, an increase of 20% year-on-year; the national photovoltaic utilization hours were 595 hours, a year-on-year increase of 19 hours. Northeast China has the highest PV utilization hours, reaching 771 hours, a year-on-year decrease of 19 hours; Central China has the lowest utilization hours, reaching 493 hours, an increase of 46 hours year-on-year.
This alone is the photovoltaic installed capacity in my country in the first half of 2020, and it also means that my country’s photovoltaic market is huge.
The photovoltaic industry is very big in our country, and everyone can get a bigger cake, and the practitioners can enjoy the industry's dividends.
First of all, we have determined that the photovoltaic industry is an industry promoted by the country and has a very promising future.
So does the photovoltaic panel need to be cleaned? The answer is necessary
The dust and dirt on the surface of the photovoltaic panel have a significant impact on its power generation efficiency.
The principle of can be mainly understood as two aspects:
Yes: The dust and stains on the surface affect the transmittance of light, which in turn affects the photovoltaic module—
The amount of radiation received by the surface;
The second is: the dust and dirt on the surface of the module block the heat transfer of the photovoltaic panel, which causes the photovoltaic panel to not release heat and increase the temperature. The temperature effect will directly affect the temperature of the module and thus affect the power output of the photovoltaic module.
The increase in the temperature of the photovoltaic panel may also cause the risk of local overheating and spontaneous combustion of the solar panel
Moreover, from the overall view of the glass cover of the photovoltaic panel, due to the corrosion of the glass cover by acid or alkaline dust, or improper cleaning, the surface roughness of the glass cover increases, the reflected light energy increases, and the refracted light energy decreases, so The light intensity incident on the photovoltaic cell is weakened, the photoelectric effect is weakened, and the power generation is reduced. Although the corrosion effect of dust accumulation is small, the damage to photovoltaic modules is permanent and it is difficult to repair. Only by strengthening the daily and correct cleaning and maintenance can the corrosion hazard of photovoltaic panels be reduced.
Let’s talk about the reality. At present, we provide a variety of photovoltaic cleaning products. With the cleaning of photovoltaics, the photovoltaic equipment of the first photovoltaic power plants needs to be fully cleaned. At present, the industry is developing very rapidly. Not only the power plants need to maintain themselves, but also many State-owned enterprises are looking for cleaning companies to complete the cleaning. There are a large number of photovoltaic operation and maintenance companies on the market. The project is to clean the photovoltaic cleaning projects across the country.
