Is Nanosolar Worth $2 Billion?

nanoIs Nanosolar worth a whopping $2 billion? Nanosolar seems to think so, at least according to a rumor being reported by CNet. The article quotes sources saying Nanosolar is valuing itself in the $2 billion-range as they shop for more funding. We contacted the company and they refused comment.

While we’re all for shameless self-promotion, we have to wonder about that valuation. Nanosolar only started selling product last December.

So what has Nanosolar got that’s worth so much? In intellectual capital, Nanosolar has a portfolio of over 180 patents in development, according to CrunchBase. In 2004 the company acquired the complete intellectual portfolio of Unisun Corp., which had filed for some of the earliest patents in printed CIGS technology.

In terms of funding, the company, founded in 2002, has raised over $100 million in capital from Sand Hill Road heavyweights like Mohr Davidow Ventures and Benchmark Capital, as well as the Google guys Larry Page and Sergey Brin. And the company won a $20 million grant from the Department of Energy as part of the Solar America Initiative.

On the facilities side, Nanosolar is working on a solar manufacturing plant in a 140,000 square-foot space previously in San Jose that used to be occupied by Cisco Systems. And according to its web site, Nanosolar has an additional 500,000 square feet of manufacturing space outside of Berlin.

So do all of these assets add up to a $2 billion valuation? Combined with the promise of making solar electricity “cost-efficient for ubiquitous deployment, mass-produced on a global scale [and] available in many versatile forms.” the answer is a definite…maybe?

So who will be the first billion-dollar biofuel startup? Or billion-dollar electric vehicle startup? Speculate in the comments below.
