Why Silicone for Solar? A Module off the Line Every 90 Seconds

Dow Corning wants to bring space age solar to the masses.

Solar panels on satellites have been coated with silicone, the rubbery stuff for household repairs, for years. It protects the solar panel from solar radiation and it also allows the module to operate at a higher efficiency because it is more transparent than other coatings.
Now, the chemical giant has begun to sell it for garden variety solar panels. The company's silicone will give panels greater durability and efficiency, but Dow says there is another attribute too.
"We are able to produce modules much faster," said Gaetan Borgers, global industry director of the Dow Corning Solar business. By switching to silicone, PV manufacturers potentially will be able to get a module off of the factory lines every 90 seconds, he said, or four times faster than with the incumbents.
