Photovoltaic bifacial module array

Should bifacial PV modules be more separated than monofacial arrays?

Bifacial modules packing on a PV plant In large PV plants, the real value of ground albedo due to shading from bifacial PV arrays is important for determining the location of these arrays. It is clear that the arrays of bifacial PV modules should be more separated than for monofacial arrays.

Can bifacial solar PV modules improve energy production?

A novel development is the advent of bifacial PV modules that enhance energy production by converting incident irradiance on the rear side of the module into electricity. Bifacial solar photovoltaics (PV) cells as a promising technology convert the photons from albedo and incident irradiance into electricity [ 2 ].

What is bifacial solar photovoltaics (PV)?

Bifacial solar photovoltaics (PV) is a promising mature technology that increases the production of electricity per square meter of PV module through the use of light absorption from the albedo.

How much energy does a bifacial PV module gain?

At albedo 0.2, an energy gain of 10% was observed, while at albedo 0.5, an energy gain of 30% was reported by . The mismatch loss of a bifacial PV module is reported to depend on the field ground (albedo) around the PV module . As reported by , the energy yield depends on the installation height.

How much bifacial gain does a PV array have?

When the distance between the module rows is fixed at 2.5 m, the bifacial gain for the PV modules in a PV array with 5 × 11 modules is presented in Fig. 21 . The performances of the modules at the edge and at the center of the field vary from 31.41% to 27.72%, which are obviously lower than a stand-alone bifacial module (33.85%). Fig. 21.

What is a bifacial PV module?

Because of its ability to generate electricity on both sides, the bifacial PV module allows for greater installation flexibility. The bifacial PV system can now be mounted vertically east-west, in addition to tilted and equator-facing orientation.
