PRODUCT 03
EagleLite®Ultra-thin Physical tempered glass Almaden is the leading supplier of ultra-thin physical tempered glass, with the most advanced
technology and production equipments.
Its ultra-thin physical tempered glass (thickness ≤ 2mm) has excellent quality and high yield.
The floating tempering process perfectly realizes the physical tempering of large-size ultra-
thin glass.

Anti-reflective coating solar glass The anti-reflective coating on solar glass enables more sunlight to be absorbed by the cell,
thus increasing the module power output. Almaden’s anti-reflective coating increases the
actual outdoor power generation by more than 4%, and continues to provide customers with
gain value.
MORE anti-reflective coating solar glass With strong scientific research strength and dedicated spirit, Almaden has successfully
developed a new generation of anti-reflective coated glass “MORE” series, which increases
the light transmittance of glass in the wide spectrum (400nm~1100nm) range by more than
3%.
White ceramic coated tempered glass The reflectivity of the highly reflective ceramic coated glass, independently developed by
Almaden, is as high as 80%, and the power gain of the module can be increased 4~6W.
Printing can be customized according to customer requirements.

The front glass thickness is ≤2mm.
The thinner glass is, the greater heat
dissipation is, which leads to more
power generation as well as lighter
weight.

The water permeability of POE is only
1/10 of EVA ， which can effectively
avoid delamination by prevent water
vapor penetration and avoid snail trail.
Encapsulate with POE
Use white ceramic coated tempered glass as the
backsheet, increasing light absorbtion effectively
and gaining 1% more yield.
The thinner glass is, the greater heat dissipation is,
which leads to more power generation as well as
lighter weight.

Frameless design，no need of grounding
Inorganic glass replacing organic backsheet，POE replacing
EVA
The dual-glass module does not require an aluminum frame and
no need of grounding, so that the electrical loop forming PID
cannot be established. Therefore, the dual-glass frameless
module can effectively prevent PID.
Use glass instead of organic backsheets, POE instead of EVA.
Glasses are impervious to water, while the water permeability of
POE is only 1/10 of EVA, thus greatly reducing the possibility of
sodium ions hydrolyzed by glass, and no conditions for PID.
