Should you use dual-glass solar modules for rooftops?

Robustness and reliability are critical for solar professionals looking for resilience in solutions designed to provide a greener future. Thus, using dual-glass solar PV modules for rooftops offers the opportunity to increase the energy efficiency of commercial and residential buildings. What are dual-glass solar modules?

Can dual-glass solar panels increase solar energy production?

Installing dual-glass panels on a reflective surface, like a white rooftop, can increase solar energy production. That’s because nowadays, dual-glass solar modules use bifacial cells throughout, and this power is generated from both sides of the panel instead of just one.

What is a dual glass solar panel?

In contrast, dual-glass solar panels replace the backsheet with a second layer of tempered glass on the rear side of the module. 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.

Are bifacial double-glass modules a good choice?

There has been a noteable shift from the initial single-facial single-glass modules to bifacial double-glass modules. Double-glass modules, with their performance in the face of salt mist, high temperatures and high humidity, have won the market’s favour. However, this trend is not without its risks.

Why is dual-glass technology important for rooftop installations?

Dual-glass technology for rooftop installations can help investors, installers, and end-users recoup their investments faster than before. Robustness and reliability are critical for solar professionals looking for resilience in solutions designed to provide a greener future.

Are dual-glass panels better than traditional panels?

While traditional panels have proven efficient and resilient in many places, they are more prone to stress from wind, snow, and other elements. 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.
