    Sorry, I am not engineer, but in short, which one should I buy if I am a investor

  2. Sneha Shah

    Dear Phanny, Both of them are good stocks with good company potential. However, please be informed that Trina Solar recently approved an arrangement to go private.

    And solar investments should be made having a long term prospective in mind. Chinese stocks tend to have lower valuations on international exchanges. You might also want to look at First Solar (NASDAQ:FSLR)

    May I know the differences in prices and performance of these solar panels? Which is better performing solar panel- Indian solar panel or Chinese solar panel?
