how can i optimize power in a Solar panel?
I am designing a Solar Panel but i need to have maximum power output.How can i optimize the equation for power Total power=voltage * current to get maximum power.
first place the panel so it is at right angles to the solar rays. Make sure none of the panel has any shade whatsoever. For best results use motor drives to keep it in that position as the sun moves across the sky.
For overall maximum versus time, you need to be near the equator.
Solar cells have a high internal resistance, so for maximum power transfer, you need a load of that same resistance. A good charge controller will use DC-DC converters to provide that load.
