Technical FAQs 3

Which bifacial double glass module produces more energy?

The bifacial double glass module produces more energy. Our N-type models have superior bifaciality. This means that the rear side of the module can produce up to 85% of the energy generated by the front side. Thus, the panel generates more energy overall. Lower degradation means a higher return on investment.

What are the standard test conditions for a polycrystalline module?

ELECTRICAL DATA Data is given at Standard Test Conditions: Irradiance 1000W/m², spectrum AM 1.5 and 25°C cell temperature All modules Polycrystalline except when indicated ‘Mono’ for Monocrystalline ⚠️ SAFETY NOTE Electrical installations should be carried out by a qualified technician. Handle chemicals with care as they are hazardous.
