electric curve of modules, especially under weak light. In more complex control circuits,
the controller supplier may have already adopted microprocessors for the tracking of
maximum power output. For the best impedance matching and the best tracking of
maximum power output, please refer to other relevant documents regarding these issues.
Electrical ratings of ET Solar modules are as follows. The detailed specs should refer to
module datasheet.
