EVER MORE EFFICIENT SOLAR.

Kyocera Solar has introduced what it calls the world’s most efficient – 15.7 percent – commercially available solar module. The term commercially available is important here. There are more efficient modules available, but not commercially available to the average consumer.

The module, as yet unnamed, utilizes multicrystal cells operating at 17.7 percent conversion efficiency. Each module will have 48 cells with a maximum output of 189.7 watts.

(Note:The relative loss of efficiency from cell to module is due to module design and construction inherent in all solar modules.)

The new product will begin production in September and be available to world markets shortly after.

Kyocera claims improved efficiency of the module is the the result of totally integrated and carefully engineered production processes as well as technologies such as the use of high-efficiency cells, low resistance wiring in each module and an improved cell fill rate. (The cells are squeezed closely together in each module.) Integrated production means Kyocera does everything in-house from raw materials processing to solar cells to finished modules.
