Which way is better to clean photovoltaic operation and maintenance cleaning?

Photovoltaic intelligent cleaning robot (Lier Sunshine cleaning robot) effectively improves power generation, this way is better to clean, photovoltaic power station intelligent cleaning is an inevitable development trend of fine operation and maintenance of power stations, only more intelligent, in order to reduce labor investment, reduce labor costs.

The surface of the photovoltaic module should be kept clean, and the photovoltaic module can be wiped with a soft and clean cloth that is dry or damp, and it is strictly forbidden to use corrosive solvents or hard objects to wipe the photovoltaic module.

There are three main ways to clean photovoltaic modules, manual cleaning, high-pressure water gun cleaning and professional equipment cleaning.

1. Manual cleaning: The cost of manual cleaning is relatively low, and it is suitable for roofs with a relatively small area. Because the personnel is not easy to manage, it is easy to wear and tear the module glass, which affects the power generation and life of the power station.

2. High-pressure water gun cleaning: The high-pressure water gun has a good cleaning effect, but the water consumption is large, and if the water gun pressure is too large, it will easily cause hidden cracks in the components.

3. Professional equipment cleaning: the water consumption of professional equipment cleaning is small; The cleaning speed is fast and the effect is good, but it is more suitable for the site with a wide distance between the front and rear of the module, due to the non-linear motion of the vehicle, the pressure on the component is uneven, and it needs to be operated by professionals.

At the same time, the bracket also needs to be maintained, and the maintenance of the bracket should ensure that all bolts and bracket connections should be firm and reliable; The anti-corrosion coating on the surface of the bracket should not crack and fall off, and if there are cracks and falling off, the paint should be repaired in time.

1. The cleaning frequency of the battery board should be ensured, and the specific situation should be determined according to the cleanliness of the surface of the battery board.

2. The operation and maintenance should be tracked diligently, the inspection should not go through the motions, and the data inspection of all aspects of the background should not be less than once an hour, and whether the tracking data has changed greatly.

3. Timely discovery of hidden dangers in a timely manner, phalanx inspection can not be less than once a day (especially at noon when the irradiance is relatively high, focus on observing the inverter and indoor temperature, to ensure good heat dissipation), to ensure that the attendance rate of power generation efficiency is high, 4, to ensure that there are a certain number of spare parts, wearing parts and other small components, to ensure that once there is a problem can be replaced in time without affecting the power generation efficiency. O&M is not only limited to the operation and maintenance of the power station, but also ensures the normal income of the power station owner, and efficient operation and maintenance can maximize the income of the power station.

Answer: Responsible for the production preparation of the new photovoltaic power station, and cooperate with the relevant departments of the company to complete the control and management of the project quality inspection process; 2. Responsible for the operation, inspection, elimination, meter reading, settlement and other related work of the photovoltaic power station after it is connected to the grid to ensure the smooth completion of the company's power generation goals; 3. Responsible for the formulation of various operation and maintenance instructions, operation and maintenance reports, and the establishment of operation and maintenance files; 4. Complete other tasks assigned by superiors.

Photovoltaic operation and maintenance can be understood in two aspects:

First, the dirtiness of the surface affects the transmittance of light, which in turn affects the amount of radiation received on the surface of the module.

Second, because the surface of the module is very close to the cell, it will form a shadow and form a hot spot effect in the local area of the PV module, which will reduce the power generation efficiency of the module and even burn the module.

Proper cleaning of photovoltaic panels can prolong the service life of photovoltaic power stations, improve the work efficiency of photovoltaic panels, and thus increase power generation.

Lier Sunshine photovoltaic panel cleaning robot is lightweight, portable, easy to load and unload, and can be carried with the vehicle, which can easily provide portability for the operation and maintenance team to work at multiple points.

Test with components as clean as possible.

Attach the temperature sensor to the backplane in advance to save time.

If the deviation between the measured value and the estimate is large, test it several times.

Check and re-check before setting off for the test, and bring an extra spare battery.

The connection between the instrument and the component to be tested must be tight, do not leave a gap, place the instrument in a room temperature environment after returning from the site, and pay attention to waterproof, moisture-proof and high-temperature protection.

Keep the irradiance sensor at the same angle as the component to be measured and pay attention to occlusion to ensure that the instrument is clean and tidy, especially the interfaces, buttons, and screen parts.

Anonymous users1. Maintenance of modules and brackets (1) The surface of photovoltaic modules should be kept clean, and the photovoltaic modules should be wiped with dry or damp soft and clean cloths, and it is strictly forbidden to use corrosive solvents or hard objects to wipe the photovoltaic modules. The PV module should be cleaned when the irradiance is lower than 200W, and the liquid with a large temperature difference with the module should not be used to clean the module. (2) Photovoltaic modules should be inspected regularly, and if the following problems are found, the photovoltaic modules should be adjusted or replaced immediately.

PV modules have glass crushing, scorching backsheets, and obvious color changes; The presence of air bubbles in the PV module that form a communication channel with the edge of the module or any circuit; The junction box of the PV module is deformed, twisted, cracked or burned, and the terminal blocks cannot be in good contact. (3) The live warning sign on the photovoltaic module shall not be lost. (4) For photovoltaic modules with metal frames, the frame and bracket should be well combined, the contact resistance between the two should not be greater than 4, and the frame must be firmly grounded.

5) When working under the condition of no shading, under the condition that the solar irradiance is more than 500W and the wind speed is not more than 2ms, the temperature difference on the outer surface of the same photovoltaic module (the area directly above the cell) should be less than 20. Photovoltaic power stations with an installed capacity of more than 50kWp should be equipped with infrared thermal imaging cameras to detect the temperature difference on the outer surface of photovoltaic modules. (6) Use a DC clamp ammeter to measure the input current of each photovoltaic module string connected to the same DC combiner box under the condition that the solar radiation intensity is basically the same, and its deviation should not exceed 5%.

7) All bolts, welds and bracket connections of the bracket should be firm and reliable, and the anti-corrosion coating on the surface should not crack and fall off, otherwise it should not be brushed in time.

Electricity price subsidy. Now the state's subsidy for the photovoltaic industry is the policy issued in August 2013, the "Notice on Leveraging to Promote the Healthy Development of the Photovoltaic Industry" (Fa Gai ** [2013] No. 1638), which stipulates the subsidy policy for distributed generation, the first subsidy of yuan kilowatt hour, and the implementation period is 20 years in principle.

The state will gradually reduce electricity prices and subsidy standards according to changes in the scale and cost of photovoltaic power generation. At the end of 2017, the state adjusted the subsidy to yuan. Various provinces and cities have formulated different subsidy standards according to policies, which are basically the following:

National subsidy + provincial subsidy + municipal subsidy + county-level subsidy (the latter three if any) = the final PV feed-in tariff.
