Cylindrical PV solar collectors - Solyndra

In the U.S. alone, approximately 30 billion square feet of commercial rooftop surface is available for PV systems and could be utilized to create in excess of 150 gigawatts of electricity. Globally, this number could be two to three times higher. Tapping even a small fraction of this potential would make a significant impact on the world’s energy needs.

Solyndra designs, manufactures and sells solar photovoltaic (PV) systems comprised of panels and mounting hardware for large, low-slope commercial rooftops. The Solyndra system is designed to optimize PV performance on commercial rooftops by converting more of the sunlight that strikes the total rooftop area into electricity.


Solyndra’s panels employ cylindrical modules which capture sunlight across a 360-degree photovoltaic surface capable of converting direct, diffuse and reflected sunlight into electricity. Solyndra’s panels perform optimally when mounted horizontally and packed closely together, thereby covering significantly more of the typically available roof area and producing more electricity per rooftop on an annual basis than a conventional panel installation. The result is significantly more solar electricity per rooftop per year.

The Solyndra system is lightweight and the panels allow wind to blow through them. These factors enable the installation of PV on a broader range of rooftops without anchoring or ballast, which are inherently problematic. The horizontal mounting and unique “air-flow” properties of Solyndra’s solar panel design substantially simplify the installation process for Solyndra’s PV systems. The ease of installation and simpler mounting hardware of the Solyndra system enables its customers to realize significant savings on installation costs.

Using proprietary cylindrical CIGS modules and thin-film technology, Solyndra systems are designed to provide the lowest installation cost per system and the highest annual solar electrical energy output for typical low slope commercial rooftops.

Solyndra Offered $535 Million Loan Guarantee by the U.S. Department of Energy

Fremont, CA, March 20, 2009 – Solyndra, Inc. announced today that it is the first company to receive an offer for a U.S. Department of Energy (DOE) loan guarantee under Title XVII of the Energy Policy Act of 2005. Solyndra, a Fremont, California-based manufacturer of innovative cylindrical photovoltaic systems, will use the proceeds of a $535 million loan from the U.S. Treasury’s Federal Financing Bank to expand its solar panel manufacturing capacity in California.

“The leadership and actions of President Barack Obama, Energy Secretary Steven Chu and the U.S. Congress were instrumental in concluding this offer for a loan guarantee,” said Solyndra CEO and founder, Dr. Chris Gronet. “The DOE Loan Guarantee Program funding will enable Solyndra to achieve the economies of scale needed to deliver solar electricity at prices that are competitive with utility rates. This expansion is really about creating new jobs while meaningfully impacting global warming.”

    I am interested in why your product is not yet available to residential markets as well as why your company would seek only commercial markets at this time? We’re a starup solar installer with an interest in marketing mostly US manufactured products. I would be interested in being able to offer your product to our customers… both residential and commercial. Can you advice if and when you will be ready and willing to offer your products to us for use in the US market? Is a price list available?
