Algeria photovoltaic bifacial modules

What is a bifacial solar module?

For a bifacial solar module, the tilt β Rear and azimuth γ M (Rear) angles of the rear side are (180 ° - β Front) and (γ M (Front) + 180 °), respectively.

Do bifacial solar modules produce more energy?

Guo et al. concluded that for an arbitrary geographic location, an albedo threshold always exists above which vertical bifacial solar modules will outperform optimally tilted monofacial counterparts. Apparently, location-specific, optimally tilted and oriented bifacial solar modules will produce even more energy than vertical modules.

How to optimize bifacial solar modules?

However, increasing the albedo to 0.5 and elevating modules 1 m above the ground can boost the bifacial gain to 30%. Moreover, we derive a set of empirical design rules, which optimize bifacial solar modules across the world and provide the groundwork for rapid assessment of the location-specific performance.

What are the deployment scenarios of bifacial solar modules?

Three different deployment scenarios of bifacial solar modules are simulated (depicted in the 1st row), i.e., (a) ground mounted with a ground albedo of 0.25, (b) ground mounted with a ground albedo of 0.5, and (c) 1 m elevated with a ground albedo of 0.5.

How much bifacial gain can a ground-mounted solar module achieve?

2. Our calculation predicts that for a low ground albedo of 0.25 corresponding to vegetation/soil, ground-mounted bifacial solar modules can only achieve bifacial gain up to 10% relative to their monofacial counterpart across the entire world (except for the Arctic and Antarctic regions).

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.
