Abstract

A method for communicating and addressing photovoltaic solar cell panels in string comprising: sending commands from a string concentrating element to a first smart diode connected in parallel with a photovoltaic panel in a string; a first photovoltaic panel in the string has the lowest voltage and a last photovoltaic panel in the string has the highest voltage, wherein the outlet of said smart diode is connected to inlet of a photovoltaic panel in the string and the inlet of said smart diode is connected to outlet of a photovoltaic panel; said first smart diode sends a signal back to said string concentrator; said string concentrator receives said signal from said first smart diode and sends an additional different command; a second smart diode connected in parallel with a further photovoltaic panel in the string receives said additional command.
