All technical schemes of parallel diode are also arranged on each solar battery sheet, but its parallel connection is generally behind backboard, implements complicatedly, required diode is also more.
[summary of the invention]
For solve above-mentioned mention can not thoroughly eliminate " heat class " phenomenon or scheme complicated problems, the utility model discloses a kind of solar module.
The utility model solar module comprises backsheet layer, adhesive layer, array, adhesive layer and the glass plate that sets gradually; Wherein, described array is made up of the capable m row of a n solar battery sheet, be in m solar battery sheet in the row and be connected in parallel and form row in parallel, be in n solar battery sheet in the row and be connected in series and form the series connection row, the bypass diode that all is parallel with a sheet is gone in each parallel connection; Described bypass diode all is packaged between backsheet layer and the glass plate.
Adopt technical solutions of the utility model, workable, good stability and can thoroughly eliminate advantage such as " hot spot " phenomenon.When having eliminated " hot spot " effect up hill and dale, can also reduce the usage quantity of diode, thereby effectively reduce cost.Be easy to realize, can farthest reduce energy loss, improve the utilization ratio of whole assembly.
