Californian thin-film firm Solyndra will supply its solar panels to Milan-based Sun System, under a USD105mDeal. The firm develops cylindrical CIGS-based photovoltaic systems for use on commercial and industrial rooftops, and produces the panels at its facilities in Fremont and Milpitas.

In July, Solyndra penned a USD238m supply deal with German project developer Umwelt-Energie. The firm claims the deal made its order backlog surpass USD2bn. Earlier this year, Solyndra received a USD535m loan guarantee from the US Department of Energy to build a manufacturing facility in California. The facility is scheduled for completion in 2011 and will have an annual capacity of 500MW.

Solyndra has raised close to USD800m in private equity funding to date from investors including Redpoint Ventures, RockPort Capital, US Venture Partners, Masdar and Virgin Green Fund.
