Product Description
Operating temperature of bifacial modules
The double-sided module has a higher working current than conventional modules due to the back light; on the other hand, the
double-sided module does not have a fully covered back aluminum, which will absorb less infrared heat

Factors Affecting Backside Generation Gain
In addition to the ground reflectivity, the main factors affecting the power generation gain on the back side are the height of
the two components above the ground, the irradiation conditions (the relationship between the direct radiation DNI and the
scattered horizontal radiation DHI), and the array spacing, etc.

Influence of installation height and location
According to the optical simulation, when the height of the module is more than 1m above the ground, the irradiance received by
the backside, the Great and the irradiance uniformity, both begin to increase to stable values.
The backside irradiation at the edge of the array will be higher, and the upper and lower rows will also be different. You can
consider the selection of the installation inclination of different MPPT branches of the inverter.

Introduction to Lamination Technology
Laminated components Cut the finished cells 1 into 5 or 1 into 6 and connect them with conductive glue
No busbar/ribbon shielding and no cell spacing, significantly improving the amount of light received
No ribbons are used and the series current is significantly reduced, reducing electrical losses
Laminated components also put forward high requirements for enterprise technology accumulation
The addition of the slicing process subverts the traditional stringing process and requires high process accuracy
Appropriate conductive adhesives need to be matched to meet stringent reliability test requirements

Introduction to Lamination Technology
Lamination technology requires the design of dedicated asymmetric cell patterns
In terms of slicing, the infrared laser equipment has already matured, and it has been widely used on half-chips
There are two types of equipment in the string, printing and dispensing, the printing type has a lower overlap width and is easy
to achieve a lower amount of conductive glue
The conductive adhesive uses pure silver as the conductive filler for higher reliability, and the polymer body has three systems:
silica gel, acrylic acid, and epoxy resin.

Half-piece solar panel power boosting principle
By cutting the cell in half, the working current of the cell is halved, the electrical loss on the ribbon is significantly
reduced, and the CTM of the module is improved.
The gap between the cells of the half-piece module is increased, and the light reflected by the backplane to the cells through the
glass increases slightly
The higher the cell current, the greater the value brought by the use of half-cell technology. High-efficiency monocrystalline
cells use half-cell technology, and the power gain is >2%
reduced, and the CTM of the module is improved.

Half-chip solar panel circuit diagram
The mainstream version of the half-chip module adopts the two-part design as shown on the right. The upper half and the lower half
are in a parallel relationship and share a bypass diode.
From the top outlet of the whole module (left picture) to the middle outlet, it is suitable for vertical installation.
