4 FAQs about Solar module production glass plate
What is the difference between glass and plastic solar modules?
Glass/Glass modules withstand air and moisture and offer best cell protection, while plastic backsheets of glass/foil modules become porous. The Glass/Glass composite protects solar cells against micro cracks and thus ensures long-term operating life of 40 years and more.
How much load can a glass/glass module handle?
TÜV tests show that Sonnenstromfabrik Glass/Glass modules can handle loads up to 8.100 Pa. Different to glass/foil modules, Glass/Glass modules are resistant to damages resulting from ammonia in agricultural and industrial installations as well as resistant to damages from salt spray in coastal regions or sand abrasion in desert regions.
How does encapsulation affect PV module reliability?
The use of an encapsulant with a lower diffusivity and/ or the use of an efficient edge sealant can further reduce the moisture ingress. This decrease in water vapour ingress has a direct positive impact on PV module reliability compared with that for a standard GBS lay-up.
Are thermoplastic polyolefin encapsulants a good choice for long-lasting PV modules?
Thermoplastic polyolefin encapsulants with water absorption less than 0.1% and no (or few) cross-linking additives have proved to be the best option for long-lasting PV modules in a glass-glass (GG) configuration.
