1、Snow cleanup

Timely cleaning of snow：After snowfall in winter, although solar tiles roof has a certain angle of inclination, but the continuous snowfall is still difficult to avoid the occurrence of snow, should be timely removal of snow on the surface of the light solar roof tiles. Snow cover will significantly reduce the ability of the solar module to receive sunlight, thus seriously affecting the power generation efficiency.

Generally, you can use soft cleaning tools, such as plastic or rubber snow shovel, gently push down the snow to avoid scratching the surface of the module.

Pay attention to the cleaning time：Try to choose to clean up the snow during the day when the temperature is relatively high, so that on the one hand, you can use the sunlight to melt part of the snow, so that the cleanup work is relatively easy; on the other hand, after cleaning up the components can resume power generation faster, reducing the loss of power generation time due to the accumulation of snow.

2、Icing treatment

Prevent the surface of solar roof tiles from icing：In some cold and humidity areas, the surface of solar panel shingle may freeze. Some preventive measures can be taken in advance before snowfall, such as spraying special anti-icing coating on the surface of the module (to ensure that the coating has no adverse effect on the performance of the module), to reduce the possibility of water icing on the surface of the module.

Safe removal of ice：If the surface of the solar tiles roof is already frozen, do not use sharp or hard tools to break the ice forcibly, so as not to damage the module. You can try to use warm water to pour slowly on the ice layer, so that the ice gradually melt, but pay attention to the water temperature should not be too high, to avoid causing damage to the components due to sudden changes in temperature, the general control of the water temperature is more appropriate at about 40 ℃.

3、Temperature impact monitoring

Monitor module temperature：Low temperature environment may have certain impact on the performance of solar module, such as reducing the conversion efficiency of the battery. By installing temperature sensors and other equipment, the temperature of the module is monitored in real time, so as to understand the operating status of the module under low temperature in time.

Data analysis and adjustment：According to the temperature monitoring data, combined with the solar system's power generation data for analysis. If it is found that the power generation efficiency decreases significantly due to low temperature, the operating parameters of the system can be adjusted appropriately (e.g., the relevant settings of the inverter, etc.) to optimize the power generation efficiency to a certain extent, but the adjustment operation needs to be carried out by the professional personnel in accordance with the operating procedures.

4、Equipment and line inspection

Line and electrical equipment inspection：carefully check the cable lines of the solar system to see if there is any damage, aging or loose joints, etc. Low temperature may make some line materials become brittle, increasing the risk of failure. At the same time, the inverter, distribution box and other electrical equipment to check to ensure its normal operation, check whether the equipment heat dissipation is good, because some equipment in the winter heat dissipation needs have been reduced, but still need to ensure that the normal heat dissipation channel is smooth, in order to prevent the equipment due to overheating or overcooling failure.

5、Daily Inspection

Increase the frequency of inspection：The weather conditions in winter are relatively harsh, and the frequency of inspection of the roof solar system should be increased appropriately, so that all kinds of potential problems can be found and dealt with in a timely manner. In addition to the above mentioned snow, ice, equipment lines and other aspects of the inspection, but also pay attention to the solar system surrounding environment whether there are abnormal changes, such as whether there is a tree branch by the snow near the solar module and other situations.

Record and feedback：During each inspection, record the inspection in detail, including the problems found, treatment measures and so on. Feedback these records to the relevant operation and maintenance team or management personnel in a timely manner, so as to summarize and continuously optimize the operation and maintenance work of the solar system.

For solar roof tiles homeowners, winter is a challenge, on the one hand, the reduction of sunshine duration and intensity will have an impact on the power generation of the solar system, on the other hand, some common extreme weather in winter is prone to damage the solar panel shingled, so take precautions well in advance to let the solar roof So taking precautions in advance to extend the service life of your solar roof tiles is also a value-added asset for you.
