As a leading player in global solar glass technology and the only solar glass manufacturer in India, Gujarat Borosil Limited (GBL) has been serving the solar power sector since it’s infancy in the country. Our many pioneering achievements and innovations include the development of world’s first 2 mm fully tempered solar glass & Antimony-free solar glass. We are glad to introduce our new product “Selene” – an Anti-glare solar glass.
As many airports have recently expressed their commitment towards environment and to reduce their carbon footprint by sourcing power from renewable energy sources, the solar photovoltaic (PV) installations near airports are on the rise. As you are aware that glare caused due to (reflection of light falling on the front glass) PV modules installed near airports may cause a severe disturbance to the pilots and is a serious safety issue for air traffic. Considering the seriousness of the issue, various aviation authorities across the world have issued guidelines and recommended the permissible levels of glare.
In order to resolve this issue, we have successfully developed an Anti-glare solar glass which can safely be used in solar PV installations near airports. The application of this anti-glare solar glass is to diffuse the sunlight and reduce the glare. We have been able to reduce reflected luminance value for our Anti-glare solar glass to 19,000 cd/m² which is within 20,000 cd/m² i.e. a prescribed limit for airport PV installations as per international standards. The SPF report confirming the suitability of our Anti-glare glass for airport PV installations is a part of a presentation attached.
We have noticed that some of the tenders that have been floated by airport authorities in the country have mentioned a requirement of “Anti-glare coating”. Anti-glare glass has a specially designed patterned surface to reduce the reflective luminance and we are worried that the glass having “Anti-reflective” coating may be passed on as an Anti-glare glass and the same may not be able to meet the safety norm of 20,000 cd/m².
We believe that apart from meeting the strict safety requirements at the airports, this innovation would help boost manufacturing of solar modules in India giving impetus to Government of India’s “Make in India” initiative as well as to help achieve their ambitious targets of renewable energy capacity of 175 GW by 2022.
