The output voltage of a solar cell is dependent on the amount of radiation on the cell.
When you connect the cell to the grid, you have to maintain its voltage at same level of the grid voltage.This is done using a Buck/Boost converter with variable duty cycle.
I read an article on wikipedia about maximum power point tracking,but I need more details about this(circuit, control system, microlcontroller), and want to know how to determine the equivalent impedence of the converter which is important in MPPT.
Thanks in advance
