Yangtze 600W solar panels rewiev after 2 years installation

hi guys, think carefully. I bought Yangtze panels and after two years I regret this decision very much. Poor quality panels, after two years of installation, the aluminum frame corroded and water got inside the panel, causing a lot of corrosion. This has happened in 5 of the 31 panels I have purchased, in 2 the center section is damaged causing less production. I have panels installed from Togo so I quickly noticed the problem. However, the worst thing is that the manufacturer's 25-year warranty is fiction. I reported the problem to the seller from Alibaba Marco Ch. who blocked me after reading the message about damaged panels.
