The glass-glass design typically operates 2-3°C cooler. While 3°C might not sound like much, let's connect it back to the temperature coefficient. Typically, for every degree Celsius (°C) above the standard test condition of 25°C (77°F), a module's power output decreases by about 0. . Use of clear back glass typically results in a “1 power class” penalty (2-5% lower power rating). Recent improvements in quality of structured, thin front glass and addition of either colored EVA or ceramic coatings on glass has largely eliminated this penalty (at a cost). 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. . With the trend towards double glass sided modules as seen in Bifacials, or TOPCon with double glass sided construction, the changes in solar PV module design and materials mean breakages are now a bigger risk than ever. 2 mm— usually just 2 mm—to reduce weight and material use (Zuboy et al. This change of thickness affects multiple risk factors for breakage, as we describe below.
