The bifacial dual sided glass module (G2G) generates more electricity by converting direct, radiant and scattered solar energy on both the front and the back side of the module.
In this paper a glass–glass module technology that uses liquid silicone encapsulation is described.
The increasing demand for higher efficiency and longer-lasting solar panels is fueling adoption, as double-glass modules offer superior durability and performance compared to traditional
By choosing heat strengthened glass panels on both sides, we have been able to use a thickness of 2.5mm and to demonstrate an excellent module resistance to all standard mechanical tests (up to
Double-glass modules boast increased reliability, especially for utility scale PV projects. These include better resistance to higher temperatures, humidity and UV conditions and have better mechanical
Our industry-leading module power contributes to a conversion efficiency of
Our industry-leading module power contributes to a conversion efficiency of 23.2%. Bifacial ratio reaches 80%,30% more module power generation than conventional modules. Two-sided double-glazed
Our SOLID series of frameless glass-glass solar modules combines high performance with modern design, offering versatile solutions for various applications. These modules are thoughtfully designed
Generally, the front and back glass layers in these modules have the same thickness, contributing to their balanced structural integrity. This design not only enhances the module''s
Compared to traditional single glass modules, double glass modules offer significant advantages, particularly in terms of efficiency and durability. The rear glass layer can absorb reflected light,
Compared to traditional glass-backsheet modules, they offer greater durability and environmental resistance. The dual-glass structure provides enhanced protection for solar cells
Empa Solar Energy Europe is a leading energy storage equipment manufacturer and integrator based in Poland, serving the European market. We specialize in C&I energy storage systems for factories and warehouses, industrial battery storage systems for heavy-duty applications, factory energy storage systems (ESS) to optimize production, commercial battery energy storage systems (BESS) for retail and offices, enterprise storage solutions for corporate campuses, industrial park energy storage for multi-tenant sites, commercial battery storage for peak shaving, industrial battery storage systems for backup power, and remote base station power solutions for telecom towers. Our portfolio also includes lithium-ion batteries, system-level battery management systems (BMS), energy conversion systems (PCS), energy storage battery system cabinets, communication cabinets for telecom and data centres, integrated PV-storage systems, distributed energy resources, deep discharge battery technology, and containerised BESS.
