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.
Claims17
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 each connected 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 directly with one solar panel of said first unconverted string portion and with said DC-DC converter;
- and
- a negative rail electrically connected directly with one solar panel of said second unconverted string portion and with said DC-DC converter.
