THE INCREASING EFFICIENCY OF THE BiSoN BIFACIAL PV MODULE, NOW REACHING 300 WP ON THE FRONT

Thanks to the recent high efficiency achievements of the BiSoN Cell with 5.17 W on the front side, produced at MegaCell's Italian factory and equipped with four busbars, it is now possible to produce a bifacial 300 Wp module with 60 cells.

Carmignano di Brenta (Padua - Italy), 18th February 2016 - Thanks to the recent high efficiency achievements of the BiSoN Cell with 5.17 W on the front side, produced at MegaCell's Italian factory and equipped with four busbars, it is now possible to produce a bifacial 300 Wp module with 60 cells.

Starting with the bifacial high efficiency (21%) N-type monocrystalline BiSoN cell, the technical staff of MegaCell has implemented a new bifacial module that adds 270 Wp of rear power to the 300 Wp front power thanks to the high bifaciality factor of 90%. The rear, when irradiated by reflected and diffused light, produces an average of 25% of the power generated by the front, and therefore the total module power (front + back) reaches 375 Watts.
The BiSoN is an advanced "glass on glass" module, with two layers both 2mm thick, which has allowed the team to construct a module with an annual power loss of just 0.3%, as opposed to losses of 0.8% from standard modules.
Tests performed by the Fraunhofer Institute show no indication of LID (Light Induced Degradation) or PID (Potential Induced Degradation), phenomena that generate initial power losses of 2-3% (LID) and severe reliability problems only three to four years after the installation of standard modules.
The technology of the BiSoN modules means that photovoltaic systems can be built which have over 50 years of useful life and produce higher amounts of energy, optimising investments and greatly reducing costs per kilowatt hour (LCOE).
With these results, MegaCell is positioned as one of the most advanced players in the entire photovoltaic industry, able to attest to the competitiveness of photovoltaic energy as opposed to fossil fuel energy sources.

LG Solar Unveils NeON R with Enhanced Aesthetics and Energy Savings

The NeON R module features "Back Contact" cell technology delivering an entirely black panel that is aesthetically pleasing and energy efficient. The cell's seamless, surface blends perfectly into nearly all rooftop designs while the module's electrodes are positioned on the rear of the cell. Using LG's N-type cell structure, the panels produce 365W of energy, up to 7.3kWp, compared to 5.8kWp of the p-type cell. The module's new design minimizes LID, thereby delivering a longer lifespan and increased energy output.
