Abstract
The inventive technology, in certain embodiments, may be generally described as a solar power generation system with a converter, which may potentially include two or more sub-converters, established intermediately of one or more strings of solar panels. Particular embodiments may involve sweet spot operation in order to achieve improvements in efficiency, and bucking of open circuit voltages by the converter in order that more panels may be placed on an individual string or substring, reducing the number of strings required for a given design, and achieving overall system and array manufacture savings.
Claims58
A solar power system comprising:
- a DC-DC converter connected within and as part of a solar power string;
- a first unconverted string portion and a second unconverted string portion of said string, said portions separated by, and in serial connection with, said DC-DC converter;
- a first pair of electrical connections connecting said DC-DC converter across said first unconverted string portion;
- a second pair of electrical connections connecting said DC-DC converter across said second unconverted string portion;
- a positive rail electrically connected with one solar panel of said first unconverted string portion and with said DC-DC converter, and
- A negative rail electrically connected with one solar panel of said second unconverted string portion and with said DC-DC converter.
A solar power system comprising:
- a string of serially connected electrical components that include solar panels;
- a DC-DC converter intermediately electrically connected within said string as a part of said string so as to define a first, solar panel string portion and a second, solar panel string portion;
- a positive rail connected with said first, solar panel string portion, and with said DC-DC converter;
- and
- a negative rail connected with said second, solar panel string portion, and connected with said DC-DC converter.
A solar power system comprising:
- a first solar power generator in serial connection with a DC-DC converter and with a second solar power generator, said DC-DC converter connected between said two solar power generators, and said two solar power generators each having a respective lower voltage end and higher voltage end;
- a positive rail electrically connected with said higher voltage end of said first solar power generator and with said DC-DC converter;
- and
- a negative rail electrically connected with said lower voltage end of said second solar power generator and with said DC-DC converter.
