Tata Power Solar has expanded its cell and module manufacturing capacity in Bengaluru with the addition of new lines capable of producing high-efficiency monocrystalline PERC (passivated emitter rear contact) modules. 

The manufacturer has added 230 MW of mono PERC capacity to its existing 300 MW cell lines. At the module end, it has added 180 MW of half-cut mono PERC line to existing 400 MW setup. With this, Tata Power Solar has reached aggregate capacity of 530 MW for cells and 580 MW modules. 

The manufacturer said the new lines could produce modules with bigger wafers (166-210 mm) and higher power output ranging from 440 watts to 530 watts with an option for bifacial modules. 

The manufacturer’s existing 300 MW cell manufacturing lines process both monocrystalline and polycrystalline wafers of 125mm and 156mm sizes.

Keeping with the trend

The Indian solar manufacturing sector, traditionally dominated by polycrystalline technology, is gradually shifting towards high-efficiency monocrystalline modules in line with the global trend and increased domestic demand for these panels. 

JMK’s quarterly solar reports show 2020 was the first year when shipments of high-efficiency monocrystalline PERC modules in India overtook multi-crystalline modules. 

Indian manufacturers are gearing to cater to this demand with the expansion of their manufacturing lines. Earlier this year, Premier Solar announced its plans to set up a factory in Telangana with an annual cell and module production capacity of 750 MW. The factory will produce polycrystalline and mono PERC cells on wafer sizes up to 210mm.  

Rival Websol Energy Systems also plans to embrace PERC technology this fiscal year.
