Websol expands TOPCon module capacity, further reduces silver use - pv magazine Global

Websol Energy System is upgrading a 600 MW PERC cell line to 750 MW TOPCon, raising its total cell capacity to around 1.35 GW by March 2027.

Indian solar manufacturer Websol Energy System has started upgrading an existing monocrystalline PERC cell line to TOPCon technology, with the project expected to be completed by March 2027.

The company is converting a 600 MW mono PERC line into a 750 MW TOPCon line at its existing facility. The upgrade will increase Websol’s total cell manufacturing capacity from 1.2 GW to approximately 1.35 GW. Once completed, TOPCon will account for around 55% of its cell capacity.

The upgraded line is expected to achieve cell efficiencies of around 25%.

Websol is also targeting further reductions in silver consumption as it transitions to TOPCon technology. TOPCon cells, which now dominate global crystalline silicon production, consume more silver than earlier technologies such as PERC, making them more sensitive to silver price volatility.
