It is not feasible to replace the two.
Photovoltaic glue cannot replace waterproof brackets. Waterproof brackets and photovoltaic glue each play their own role in the roof structure. The waterproof bracket can ensure that there is no gap between the photovoltaic modules and the roof, thereby avoiding the occurrence of water seepage; photovoltaic glue can increase the adhesion and sealing of the photovoltaic modules, thereby ensuring the long-term stable operation of the photovoltaic modules.
