Tempered glass – with high mechanical resistance and increased resistance to surface temperature difference. Obtained by subjecting regular glass to appropriate heat treatment. High transmittance of glass with a low iron content, 3.2 mm thick;
EVA sheet – EVA is a polymer-based thermosetting sheet acting as binder for glass lamination. Before heating, EVA is a translucent sheet on both sides, which becomes transparent in the thermosetting process. Its properties remain stable even if exposed to changeable ambient conditions. High transparency. Good and stable adhesion to various materials. Ensures excellent resistance to heat, moisture, UV radiation and provides high reliability over long-term use with changeable conditions occurring in outdoor applications.
Combined cells – Voltage on a single cell is small (circa 0.5V). In order to obtain a greater capacity, cells are combined in an appropriate manner. Standard panels with capacity of 250Wp are usually composed of 60 cells.
