Pressing Block Installation
In this system, pressing blocks can be used to fix single solar panels or connect multiple solar panels. It is
recommended that you place the panels vertically during use to ensure the stability of the system.
Please use a certain number of pressing blocks and M8 bolts to fix the module on the bracket. Each module must
be fixed with at least four pressing blocks. The applied torque is 16–20 N·m. You need to purchase the pressing
blocks and the bolt kit yourself.Please make sure the length of the pressing blocks is over 50mm,and the
thickness is over 3mm.

Considering the actual situation of local wind load and snow load, you may need to use other means to ensure
the stability of the system, such as increasing the number of pressing blocks, strengthening the mounting holes,
or increasing the length of the pressing blocks.
Do not allow deformation of the aluminum frame caused by the pressure of the pressing block. At the same time,
do not use pressing blocks that are too thick and cast shadows over the module.
It is necessary to ensure that the pressing block is in contact with the surface of the solar panel for more than
7mm, and to avoid blocking the front of the solar panel.
Care and Maintenance
The following maintenance is recommended to maintain optimal performance of the module:
When there is dust accumulation on the glass surface of the solar panel, please clean it with a soft sponge or
damp cloth. To remove stubborn dirt, you can wipe it with a mild detergent. It is recommended to clean in the
morning and evening when sunlight is weak (irradiance ≤ 200W/m
Prevent the accumulation of leaves and other debris on the surface of solar panels. Otherwise, this will not only
affect the efficiency of power generation but also cause excessive local current and burn solar components.
Check electrical and mechanical connections at least every six months to confirm that they are clean, secure, and
undamaged.
