Nominal 12v PANELS - Ideal for small installations with 36 cells

Nominal 24v PANELS - Ideal for small 24V installations with 72 cells

"60 cells" panels - With 60 cells, wrongly called 24v, these panels are the most used in self-consumption facilities, and for that reason, their price is more competitive (€ / W) than 12 and 24V. However, they need an MPPT controller for use in stand-alone off-grid systems.
