What is a double glass c-Si PV module?

Recently several double-glass (also called glass–glass or dual-glass modules) c-Si PV modules have been launched on the market, many of them by major PV manufacturers. These modules use a sheet of tempered glass at the rear of the module instead of the conventional polymer-based backsheet. There are several reasons why this structure is appealing.

What is the best double-glass module?

When it comes to double-glass, Trina Solar’s double-glass module is the most sought after product in the market. As one of the first batch of companies that promote and commercialize double-glass modules, Trina Solar makes its double-glass modules, which has won industry-wide recognition for its high quality.

Why is white double glass PV module more powerful than transparent?

Due to the high reflectance of white EVA, the power of white double glass module is higher than that of transparent double glass module by 2-4%. Double glass PV modules is an area of significant investigation by many companies and institutes in recent years, for example Dupont, Trina, Apollon, SERIS, MIT, Meyer Burger and Talesun.

What is double glass PV module?

Double glass PV module is known as the ultimate solution for the module encapsulation technique. Although double glass modules have many advantages, they are not yet widely used in photovoltaic power plants, for which one important reason is the large power loss due to the transmission of light in the cell gap region.

Do double glass modules have a better resistance to PID?

Double glass modules have superior moisture barrier properties and are expected to have a much better resistance to PID. Four Double-glass modules were subjected to a PID test under different conditions (-1000V, 65°C and 85°C, 85% R.H.) for 96 hours.

Are double glass modules better than traditional modules?

Compared to traditional modules with backsheet, modules with double glass are stronger and more durable, presenting less degradation due to thermal cycling stress. Results from the thermal cycling test up to 400 cycles show about 35% to 43% less degradation with double- glass modules than with traditional modules with backsheet (Fig. 3).
