The pilot solar power plant installed in the Atacama desert is a success for the production of solar energy: this bifacial photovoltaic module is able to generate up to 44% more compared to fixed monofacial technology.

The tests carried out so far with bifacial photovoltaic modules, capable of producing solar energy on both sides of the panel, position itself as the photovoltaic technology of the future, because they increase the efficiency of photovoltaic solar panels.

According to the data collected in the ATAMOSTEC installations in the Atacama desert, the “ATAMO” module has a additional profit on annual average of 11% compared to a “PERC” type monofacial module installed in a fixed system inclined at 20 °, without a device carrying out solar tracking.

Using “ATAMO” in a single horizontal axis tracking system (bifacial HSAT) further improves power generation by up to 31% more gain. By combining these improvements, a gain of 44% is obtained on annual average, compared to a fixed monofacial modulus.

The technologies installed were developed by the international partners ATAMOSTEC CEA-INES from France and ISC-Konstanz from Germany.

This means that if the data is extrapolated to a commercial 100 MWp plant, version 1 of “ATAMO” could generate up to 27 GWh / year of additional energy and, combined with a monitoring system, up to 112 GWh. / year of additional energy in compared to a fixed monofacial photovoltaic installation during a normal year.
