Precautions during the installation of photovoltaic modules
Time: 2020-10-10

Conventional solar module installation methods include mounting holes, pressure blocks, and chutes. Different installation methods will match different external load requirements. Either way, when solar modules are installed on the roof, the load-bearing capacity and waterproof performance of the roof must be considered. Installing a photovoltaic system on the roof will increase the constant load of the roof, which requires the building design unit to check the load-bearing capacity . The additional photovoltaic system on the roof can reduce the cooling/heating load of the building to a certain extent, thereby reducing the energy consumption of the building.


       During the storage, transportation, and installation of solar photovoltaic modules, no collision or damage is allowed, and special attention must be paid to prevent the backing material on the glass surface and back of the module from being directly impacted by hard objects. The solar cell components should be free from deformation, glass damage, scratches and cracks. At the same time, you should pay attention to installation problems during installation


       1. It is strictly forbidden to install solar modules under bad weather conditions;


       2. It is strictly forbidden to connect the positive and negative quick plugs of the same solar module cable;


       3. It is strictly forbidden to touch the metal live parts of the solar module string;


       4. Only solar modules of the same size and model can be connected in series;


       5. The use of solar module backplane (EVA) is prohibited if it is damaged;


       6. It is strictly forbidden to lift the components by pulling the junction box or connecting wires;


       7. When installing the upper battery board, be careful that the battery board frame scratches the installed battery board during transportation;


       8. The unpacked solar panels at the construction site must be placed face up, with wooden pallets or solar panel packaging at the bottom. It is strictly forbidden to place them upright, diagonally or in the air, and it is strictly forbidden to expose the back of the modules directly to the sun;


       9. It is strictly forbidden to step on the battery panel to avoid damage to the module or personal injury; it is strictly forbidden to squeeze or hit, bump, or scratch the tempered glass of the photovoltaic module with sharp objects;


       10. Components with open circuit voltage exceeding 50V and components with maximum rated voltage of the system exceeding 50V should have eye-catching electric shock warning signs near the component connection device.


       11. Sangong Optoelectronics is committed to the research and development, production, sales and service of laser processing equipment and complete sets of solar equipment, and provides customers with complete application solutions. The solar module production line can be customized according to customer production needs.
