Bifacial Solar Panels: Dual-Sided Generation Explained
Bifacial modules collect light on both faces, converting reflected and diffuse irradiance striking the rear of the cell into additional current. On the right surface, at the right mounting height, that rear contribution can add between five and twenty percent to annual energy for very little extra module cost. It is one of the most cost-effective yield gains available in utility-scale design. It is also one of the most frequently mishandled inputs to electrical design. The extra energy arrives as extra current, and current is exactly what the balance-of-system equipment is sized against. NEUTRON supplies the combining and protection stage behind the array — combiner boxes, direct-current control and protection, busbar components and surge protection — and bifacial arrays routinely arrive with equipment specified against front-side nameplate figures that the array will exceed on its first clear day.
