What is a double glass solar module?

In the ever-evolving world of photovoltaic technology, double glass solar modules are emerging as a game-changer. By encapsulating solar cells between two layers of glass, these modules offer unparalleled durability and efficiency. But what exactly sets them apart? What are double glass solar modules?

What is a double glass module?

In contrast, double glass modules replace the polymer layer with another glass sheet, creating a robust sandwich structure. At IBC SOLAR, we use 2,0 mm x 2,0 mm glass layers, whereas some other market offerings use thinner 1,6 mm x 1,6 mm layers. This ensures greater durability and longevity.

How does glass transmittance affect the power generation efficiency?

This will in turn influence the PV module temperature and thus the power generation efficiency . The glass transmittance acts as an important factor affecting both the thermo-optical properties of the STPV unit itself and the overall performance of the combined system (STPV-DSF).

What is the transmittance of PV glass?

The transmittance of PV glass, which is the ratio of the light transmitted through it to the incident light varies with different PV coverage rates (area proportion of photovoltaic cells) and different materials of PV modules.

Why is glass transmittance important in STPV-DSF?

The glass transmittance acts as an important factor affecting both the thermo-optical properties of the STPV unit itself and the overall performance of the combined system (STPV-DSF). Chow et al. reported a solar cell transmittance in the range of 45%-55% could achieve the best electricity saving in Hong Kong.

Why are double glass solar panels bifacial?

Thermal stability: The identical thermal expansion coefficients of the glass layers minimize stress on solar cells during temperature fluctuations. Dual-sided energy Capture: Many double glass modules are bifacial, allowing them to harness sunlight from both sides.
