After five years of product development, Nanosolar has shipped its first solar panels priced at $1 a watt, the price at which solar energy gets cheaper than coal.
Panels features include:
- World’s first printed thin-film solar cell in a commercial panel product
- World’s first thin-film solar cell with a low-cost back-contact capability
- World’s lowest-cost solar panel (as little as $.99/Watt)
- World’s highest-current thin-film solar panel, delivering five times the current of any other thin-film panel on the market today and thus simplifying system deployment
- Intensely systems-optimized product with the lowest balance-of-system cost of any thin-film panel

First shipping panels have been shipped for deployment in Eastern Germany.
Popular Science Magazine has awarded Nanosolar's solar electricity technology the top Innovation of the Year 2007.
Nanosolar has already raised $100 million to build a factory, and has secured more than 600,000 feet of manufacturing space.
Worth noting that the company already has orders for the first 18 months of manufacturing capacity.
