Photovoltaic racking in the whole photovoltaic power generation system plays and its important part, then how can we distinguish solar photovoltaic mount installation is qualified safety?

1, see whether the photovoltaic bracket and its pv accessories are installed correctly, first of all, check whether there is obvious bending and deformation of the bracket imagine;

3, carefully check whether there is rust and corrosion between the installed PV bracket and bolts, and whether there is welding slag at the connection points of the bracket;

If there is no problem after checking all the above three issues, then basically the installation of PV rack is relatively qualified. If it is a roof mounted PV bracket, you also need to measure the counterweight of the PV structure, usually using cement briquettes, however, there is no strict industry standard for the size and weight of cement briquettes, which is usually determined by the system design company according to the site conditions.
