Do you want to in snowy clean solar pv systems?

Also if there is a heavy snow accumulation on the component is need to clean, can use soft items will be pushed down snow, be careful not to scratch the glass. Component is a bearing, but can't step on the components above the cleaning, will cause the component, cracked or damage to the film

if snow accumulated on the parts after the heavy snow, the need to clean it, and you can use the soft object pushes snow, be careful not to scratch the glass. Parts have a certain carrying capacity, but can't trample on cleaning, it will result in the crack of the parts or damaged, affect the service life of parts. Generally recommend that don't wait to wash again when the snow is too thick, so as to avoid excessive frozen parts. Photovoltaic system power is affected by temperature. Direct influence factor is the radiation intensity, sunshine time and working temperature of the solar cell components. Winter radiation intensity is weak, the sunshine time is short, generating less than summer is inevitable, this is normal phenomenon. However, due to the distributed photovoltaic systems are connected to the grid, as long as there is electric power grid, the family will not appear the lack of electricity load and power outages. Under the weak light of photovoltaic battery module can be in a certain power, but due to the continuous rain or fog, the solar irradiance is low, if the working voltage of pv systems are not up to the start voltage of the inverter, the system will be unable to work. The interconnection of distributed photovoltaic power generation system and distribution network parallel operation. When distributed photovoltaic power generation system can't satisfy the load demand or unable to work due to cloudy, grid power will be added automatically, there is no lack of electricity and power outages. Photovoltaic products well advised to choose a good reputation and good after-sales service. The qualified products can reduce the incidence of failure. Users should strictly abide by the system product user manuals, and regular inspection and cleaning system. Need to check the parts according to the supplier instructions for maintenance. Major maintenance of the system is to wipe components. Usually, the heavy rain area does not need to manually to wipe, in the rainy season about to clean once a month. Fall area with a large number of dust can be appropriate to increase the number to wipe. More areas should keep clear of snow, snow avoid uneven shade, influence power and snowmelt and cleared of trees of the block or clutter. The efficiency of photovoltaic power generation systems affected by external damage, including shielding, ash layer, component attenuation, temperature influence, component matching, MPPT accuracy, efficiency, efficiency of transformer, DC and ac inverter circuit loss, etc. , as shown in the figure below: each factor's influence on the efficiency are also different. For the optimization design of the system should be paid attention to the early stage of the project, in the process of project operation should take some measures to reduce dust and other shielding effect of the system. Photovoltaic (pv) grid system qualified components must go through rigorous testing, such as static load (before The wind load, snow load) After 5400 pa, static load ( The wind load) At 23 m/s speed 2400 pa, hail impact of 25 mm in diameter, so the hail will not bring harm to photovoltaic power generation systems. Under the weak light of photovoltaic battery module can be in a certain power, but due to the continuous rain or fog, the solar irradiance is low, if the working voltage of pv systems are not up to the start voltage of the inverter, the system will be unable to work. The interconnection of distributed photovoltaic power generation system and distribution network parallel operation. When distributed photovoltaic power generation system can't satisfy the load demand or unable to work due to cloudy, grid power will be added automatically, there is no lack of electricity and power outages.
