Fun fact: We can't sell you a panel that is not German. (well, engineering anyway)
You see, all panels are using German engineering and technology in them, however, if you buy them in Australia, there are only a handful of exceptions to the rule.
If someone is claiming to sell you German panels, you should be suspicious of everything they say, as usually this is a sign of poor quality. People see German and think it must be superior to Chinese made. This is a way of dodgy, usually Chinese, companies trying to trick the dummies and uneducated into a quick sale. The word German is a great way of disguising your product!
The truth of the matter is that the best panels in the world now come from China, and the Chinese control all the world's silicone so they control the quality of cells that other countries manufacturers can access.
Case in point this panel here, German engineered and Chinese made. Always make sure you check the back story of your product's and know what you are buying!
