Technical FAQs 4

Why do solar panels have two sheets of glass?

The combined strength of using two sheets of glass makes the solar panel less prone to becoming deformed or for microcracks to form in the cells. Installing dual-glass panels on a reflective surface, like a white rooftop, can increase solar energy production.

What is a double glass solar panel?

Traditional solar panels typically feature a glass front and a polymer backsheet. 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.

What are glass-glass PV modules?

Glass-glass PV modules, also known as double glass solar panels, are photovoltaic modules encapsulated with tempered glass on both the front and back sides. Compared to traditional glass-backsheet modules, they offer greater durability and environmental resistance.

What is a dual-glass solar panel?

Dual-glass modules have glass sheets on the front and back. Both sheets are of the same thickness. There’s also a neutral layer in the middle that doesn’t face any compressive stress. That allows double-glass solar panels to offer more mechanical protection, which leads to better cell protection and extends their lifetime usage. 2. Extended power
