Table 1 below shows the test result of the solar double-glass assemblies in this example, and the power package of solar double-glass assemblies is lost with the sun
The string spacing of energy battery strings group 1 increases and reduces, and specifically, as a example by cell piece 12 typesetting is for 6*10 specification, its meaning is phase
With arranging in the solaode string group 1 of area that 6 Battery pack strings 11, every Battery pack string 11 arrange 10 cell pieces 12.Cell piece
When 12 typesettings change from 6*10 to 4*10, the number of the cell piece 12 of every Battery pack string 11 is constant, correspondingly, and cell piece 12 spacing
Constant, the group number of battery strings 11 is respectively 4 groups, 5 groups and 6 groups, when cell piece 12 typesetting is 4*10 specification, battery strings 11 go here and there away from
For 72.4mm, now the power package loss of solar double-glass assemblies is between-0.54% to-0.21%, when cell piece 12 typesetting is 5*
During 10 specification, battery strings 11 is gone here and there away from for 34.3mm, and now the power package loss of solar double-glass assemblies is between 1.40% to 1.67%,
When cell piece 12 typesetting is 6*10 specification, battery strings 11 is gone here and there away from for 7.1mm, and the now power package loss of solar double-glass assemblies is
Between 2.45% to 2.82%, during it can thus be seen that cell piece 12 typesetting changes from 6*10 to 4*10, the power of solar double-glass assemblies
Encapsulation loss can be reduced to-0.54%, wherein, power package costing bio disturbance formula from 2.82%: power package loss=(1-group
Part measures power/assembly theoretical power (horse-power)) * 100%, above example proves by cell piece 12 arrangement design in change solar double-glass assemblies
The problem that solar double-glass assemblies output is low can be solved.
