A SYSTEM FOR DETECTING UTILIZATION OF MAXIMUM AVAILABLE POWER FROM A SOURCE COMPRISING: A SOLAR-CELL PROVIDING A SOUCE OF A POWER, A LOAD CONNECTED ACROSS SAID SOLAR-CELL, A HALL EFFECT DEVICE INCLUDING OUTPUT MEANS, MEANS CONNECTING SAID HALL EFFECT DEVICE IN SERIES WITH SAID GIVEN LOAD AND SAID SOLAR-CELL, MEANS FOR SUBJECTING SAID HALL EFFECT DEVICE TO A MAGNETIC FIELD PROPORTIONAL TO SOLAR-CELL OUTPUT VOLTAGE, A PAIR OF CAPACITORS CONNECTED IN SERIES, MEANS FOR SELECTIVELY CONNECTING EACH OF SAID CAPACITORS ACROSS SAID OUTPUT MEANS OF SAID HALL EFFECT DEVICE, A POLARIZED RELAY INCLUDING A SINGLE RELAY COIL CONNECTED ACROSS SAID SERIES CONNECTED CAPACITORS, SAID POLARIZED RELAY FURTHER INCLUDING A MOVABLE MEMBER NORMALLY BIASED TO A NEUTRAL POSITION BUT MOVABLE MEMBER NORMALLY EXTREME POSITION AS A RESULT OF CURRENT FLOW WITHIN SAID RELAY COIL, AND MEANS OPERABLE WHEN ONE OF SAID CAPACITORS IS CONNECTED ACROSS SAID OUTPUT LEADS OF SAID HALL EFFECT DEVICE FOR INCREMENTALLY CHANGING THE GIVEN LOAD ACROSS SAID SOLAR-CELL, WHEREBY SAID MOVABLE MEMBER OF SAID POLARIZED RELAY REMAINS IN SAID NEUTRAL POSITION ONLY WHEN MAXIMUM POWER UTILIZATION OF SAID SOLAR-CELL BY SAID LOAD OCCURS.
