Claim 0:
1. An apparatus for maximizing a power of a multi module solar string power generation system, comprising:
at least one multi module solar string which comprises solar panels having different power productions;
a DC bus, connected to said string;
a solar inverter, connected to said DC bus, for converting a solar DC power, from said at least one string, to AC power; and
an Injection Circuit (IC), connected to said DC bus and to said string, wherein said IC is also connected to at least one solar panel, of said string, and wherein said IC regulates a power production of said connected string and utilizes an excess power, left after regulating the power of said string, from said at least one solar panel to said solar inverter using said DC bus, comprising:
a first Maximum Power Point Tracking (MPPT) mechanism, for finding a Maximum Power Point (MPP) of at least part of said string;
a second MPPT mechanism, for finding the MPP of said at least one solar panel, connected to said IC;
a first DC/DC converter, for regulating a power of said connected string by converting some of a power, from said at least one solar panel, to regulating power for said connected string; and
a second DC/DC converter, for converting and utilizing, the excess power, left after regulating the power of said string, from said at least one solar panel, to said solar inverter using said DC bus.
