Dear Sir Topsun,

안녕하십니까?  

처음 뵙겠습니다. 야스다라고합니다

I hope you are in the best your health. 

I saw your company solar module information on the internet and I found model name as the below. 

※TOPSUN TSH-S500CB2BK (mono) = I assume as its efficiency is around 20%.

I tried to download its catalog from your company website but I could not do due to error. 

I appreciate if you can send me PDF catalog of the above module(500kw) and 400kw class.  

Also, I hope you understand my English and apologize my insufficient explanation. 

Cordially yours, Yasuda
