Double-side photovoltaic assembly

Abstract

The invention provides a double-side photovoltaic assembly, and relates to the technical field of photovoltaic assemblies. The double-side photovoltaic assembly comprises at least one battery group, abypass diode connected with corresponding battery groove in parallel, and a shield fixed on a backboard; each battery group is composed of batteries in parallel connection, and each battery is composed of cells in serial connection; at least part of the cells shielded by the shield are shielded cells; the battery with the shielded cells is a shielded battery; and the number of the shielded cellsin each shielded battery is greater than or equivalent to 2. Via the double-side photovoltaic assembly, influence of back-side shading on the generating capacity can be reduced, result caused by a hotspot effect can be slowed, and the service life of the assembly is prolonged.

Description
