Do bifacial modules increase energy yield?

As long as only front side power defines the the module's name plate the usage of bifacial modules leads to an increased energy yield for equal nominal power, i.e. a higher specific yield and performance ratio is to be expected. a.

Why are double glass modules symmetrical?

Mechanical constraints on cells: the fact that the structure of the double glass modules is symmetrical implies that the cells are located on a so-called neutral line, the upper part of the module being in compression during a downward mechanical load and the lower glass surface being in tension.

What is a dual-glass module?

Dual-glass type modules (also called double glass or glass-glass) are made up of two glass surfaces, on the front and on the rear with a thickness of 2.0 mm each. Some manufacturers, in order to reduce the weight of the modules, have opted for a thickness of 1.6 mm. DualSun has chosen to stay with a thickness of 2.0 mm for reasons explained below.

What is double glass encapsulation?

Hermetic encapsulation: the double glass modules offer a hermetic structure, resistant to aggressive weather conditions, the main one being moisture penetration highlighted during tests so-called Damp Heat, according to standard IEC 61215-2: 2021 (clause MQT13).

What is the thickness of a glass module?

The thickness of the front glass generally used for this type of structure is 3.2 mm. Dual-glass type modules (also called double glass or glass-glass) are made up of two glass surfaces, on the front and on the rear with a thickness of 2.0 mm each.

How much does a dual sun module weigh?

For example, for a DualSun module with dimensions 1722 mm x 1134 mm, the weight in glass (2.8 mm) - backsheet configuration is 20.0 kg while it is 25.1 kg for bi-glass (2 x 2.0 mm), which corresponds to a weight increase of 25%.
