Solar panels 30% cheaper!
By announcing solar panels of 100 W at less than 250 euros with an efficiency close to 20%, the manufacturer Galix is likely to cause a small stir in this market. Indeed, today, the most efficient panels have identical yields with Back-Contact cells from Sun Power, but for around 350 euros (100 euros more!).
To produce its panels, this company based in France (Bas-Rhin) uses PERC (Passivated Emiter Rear Cell) cells. These absorb more light than conventional cells, which gives better performance in low light conditions.
A "tiled" montage
This manufacturer does not depend on Sun Power (like most of the current manufacturers), but above all it uses a very particular assembly of these cells. Indeed, the design of the module is carried out with cells cut then connected in series and in parallel by overlapping, and glued with a conductive glue. This eliminates the use of tin on the surface, reduces the resistance and optimizes the useful photovoltaic surface. Made in series, this assembly is visible at the level of the connectors which are found at the 2 ends of the panel (and not side by side as on the other panels).
The cut cells make it possible to decrease the operating temperature of the module by 2°C, to increase the lifespan and productivity of the panels (a panel that heats up ages faster).
In the end, the use of these tiled cells offers a 15% higher yield compared to conventional panels. And as they are offered at a lower price, there is no doubt that they should soon be used on our boats
