Nanolsolar Inc. has been talking big lately about making a leap in solar panel technology that will drop the cost to under $1 a watt. The current standard for solar panels has been hovering around $4 a watt (wholesale cost) for a while.
Well, on December 18th Nanosolar announced their first shipment of solar panels that are profitably produced at $.99 a watt. Batch 1 went to a solar electricity utility in Germany and residential panels won’t be available for at least 12 months.
The big jump down in price was due to their new no-silicon method of printing a copper-indium-gallium-diselenide nanoparticle ink onto a metallic film substrate with inkjet technology. And, fortunately for us, this new type of panel will maintain the current 15%-20% standard of efficiency found in crystalline silicon panels!
Because of their ease of production and short-circuiting the current silicon shortage, I think this announcement will herald in the age of a flood of cheap solar power for everyone. And with the advent of new batteries for home energy storage like the nanosilicon wire lithium-ion cell (technical paper for the true geek here) in development now, the power grid may just become one more way to date films and old photos.
