Borosil’s innovation reduces rates and improves viability of solar power
price per unit of solar power is set to lose value, thanks to an innovation by Borosil, the wellknown glassmaker. The new technology is innovated by Gujarat Borosil Ltd (GBL) and is set up at Bharuch, Gujarat. GBL has so far invested 200 crore on the facility, promoted by Borosil Glass Works Ltd. The investment includes the 55 crore on the new plant which has set up a 150-ton per day low iron-patterned glass furnace for manufacturing high-transmission glass used in solar industry. “The output of solar glass, with this capacity, is enough to manufacture modules to produce 1 GB of solar modules annually,” said Pradeep Kheruka, Vice-Chairman, Borosil Glass Works.
The company has successfully completed production trials of the fully-tempered 2-mm solar glass, which is expected to herald a quantum leap in the mission to increase the efficiency of solar modules. “This would further lower the cost of power and significantly improve the viability of solar power for consumers,” Kheruka said.
The 2-mm tempered glass is not only lighter than the current world standard of 3.2 mm, but also absorbs less solar energy while allowing higher irradiance to reach the solar cell. This will help in harnessing solar energy more efficiently than before. The Borosil 2-mm textured solar glass has the lowest iron content in the world, free of toxic antimony and arsenic, and its anti-reflective coating makes it durable. The product and the facility have been professionally accredited globally for compliance with international standards by TUV Rheinland, Germany, SPF Switzerland and Westpak, USA. The innovation can also be used in setting up floatable solar plants on water bodies, including oceans.
