Yes. When solar energy is not used, wrap the holes at both ends of the solar panel with aluminum foil tape to form a closed space inside the tape. External dust and water vapor will not penetrate inside, which can play a protective role. A solar panel (also called a solar cell module) is an assembly of several solar cells. It forms the core part of the solar power generation system and is also the most important part of the solar power generation system.
The outer pipes of the solar panels are wrapped with special pipe insulation cotton. Purchase special pipe insulation cotton according to the diameter of the water pipe, and wrap it from the inlet to the interface of the solar water heater insulation box. The exterior is wrapped and attached with a reflective foil layer. A waitParticular attention must be paid here, the insulating layer must be on the inside to prevent the wall penetration from being frozen. Also pay attention to the insulation at the interface with the insulating box, and wrap the joint as a whole.
