Systems and methods for photovoltaic micro-inverter power harvesting efficiency increase in shaded conditions

A method and system are disclosed for producing electricity from solar radiation using a solar panel that efficiently produces electricity and is protected against cell burnout in partial shaded conditions. Short length substrings are independently connected to corresponding collector circuits to provide electricity at less than the burnout threshold of a shaded cell. Direct current power from each substring is independently optimized, collected and may be inverted to alternating current.
