PV Modules: Bifacial technology

go PV Current status Fixed installations vs 1-axis tracking First bifacial installations were fixed. • However Single-axis tracking (aka HSAT - Horizontal Single Axis Traking) is a cost-effective deployment strategy for large-scale ground-mount photovoltaic systems in regions with high direct-normal irradiance. • Bifacial modules in 1-axis-tracking systems boost energy yield by 4%-15% depending on module type and ground albedo, with a global average of 9%. This benefit is in addition to the 15%-25% energy gain already afforded by single-axis tracking relative to fixed-tilt deployments. Currently, lower LCOE values are being obtained with bifacial+HSAT (< 0.02 $/kWh) Energy Gain (%) Simulated, albedo 0.35 Location: Haining, China 25% Monofacial Fixed + 10-25% Monofacial Tracking Bifacial 20% +4-15% Tracking 15% 10% Pelaez et al.
