| ES OEM cells
Ergon Solair through its vertical market experience can assist in organizing the
production of OEM cells, procuring the wafers and managing the production with
highly qualified partners in Taiwan with whom we have a consolidated relationship.
OEM cells tupes:
2 bus bar and 3 bus bar multicrystalline 156x156mm
2 bus bar and 3 bus bar monocrystalline 156x156mm (pseudosquare and full square)
Efficiencies can reach over 17% average
Typical values of standard 2BB Multicrystalline cells
