About Solyndra: The Rooftop Solar Leader
Headquartered in Fremont, California, Solyndra designs and manufactures solar photovoltaic (PV) systems, comprised of panels and mounts, for the commercial rooftop market. Solyndra’s technology is a proven and scalable solar solution that offers strong ROI and economics for the rooftop owner. The company has installed its systems on more than 1000 rooftops in more than 20 countries. In 2010 Solyndra was named “One of the 50 Most Innovative Companies in the World” by MIT’s Technology Review Magazine. Using innovative cylindrical modules and thin film CIGS technology, Solyndra systems are designed to provide the lowest levelized cost of electricity and the highest kilowatt hour production per rooftop for typical installations. The unique Solyndra form factor is designed specifically for the commercial rooftop, offering the fastest and easiest installation, a non-penetrating mounting system, and superior wind, snow and soiling performance. In addition Solyndra offers energy and conservation advantages when installed in conjunction with a white or “cool” roof.
Founded in 2005, today the company manufactures its products entirely in the United States in a state-of-the-art 300,000 square foot front-end manufacturing factory and a 500,000 square foot back-end facility. The manufacturing facility has helped Solyndra drive costs down dramatically allowing the company to offer highly competitive “all in” installed cost on the rooftop. In 2011 Solyndra will double it’s production capacity, ramping toward 300MW. The company employs approximately 1050 employees around the world and has offices in the United States, Switzerland, Germany, Italy, and France. Revenues were approximately $140 million in 2010.
Solyndra Cylindrical Module
Benefits of a Cylinder
Solyndra designs and manufactures proprietary cylindrical modules incorporating copper indium gallium diselenide (CIGS) thin-film technology. Our panels employ cylindrical modules which capture sunlight across a 360-degree photovoltaic surface capable of converting direct, diffuse and reflected sunlight into electricity. In the industry sometimes panels are referred to as modules; at Solyndra, each panel is made up of individual modules.
A Solyndra module starts in our front-end facility as a glass tube and passes through a complex, highly-automated manufacturing process and rigorous quality control before emerging as an encapsulated package ready to efficiently convert energy from the sun. There are approximately 23 steps to build and protect the 195 thin-film solar cells created in the manufacture of each module, encompassing cleaning, deposition, scribing, binning, insertion, filling, testing, panel framing and flash testing.
Each module in a 200 Series panel has 195 individual solar cells.The inner cylinder is protected by a liquid optical coupling agent (OCA) which serves as a moisture barrier and increases the active solar cell surface of the internal tube.
Each module is designed to produce electricity for more than 25 years in the harsh environment of the rooftop.The hermetic seal on our glass tubes ensure the CIGS material inside remains protected from contamination. Each tube is helium leak tested.
Solyndra’s factory has produced over 16 million modules and each day produces approximately 1000 panels or 40,000 modules ramping to more than 3000 panels a day in 2013.
Broader Shoulders: More Power During the Day
The tubular design of a Solyndra module is “self-tracking”. Collecting light around a 360 degree surface allows it to capture more light early and late in the day. with broader shoulders and less peak during the day. This consistent power generation during the day allows the use of a smaller inverter, saving costs and benefits the overall energy yield of a system over time.
Advantages with Snow and Soiling
Because of our unique design, light snow falls through the Solyndra panels and the panels actually benefit from the increased albedo (reflected light) from a fresh snowfall. Solyndra systems experience less system loss due to snow.
The cylindrical design attracts less dirt and airborne particles, and moisture or rain that lands or forms on the modules works to clean the cylinders. Research shows that energy loss due to soiling on Solyndra systems is approximately half of that for conventional flat panels.
Fastest, Easiest-to-Install Rooftop Solar System
Solyndra 200 Series: Fastest, Easiest to Install Rooftop Solar System
200 Series Solar Panel Mounts Require No Tools
Light weight and simple installation means fast projects and low cost. The 200 Series requires no tools for installation. The light weight panels install without penetrations or array grounding, making this the easiest and fastest-to-install rooftop solar system yet. Ideal for older or “value engineered” buildings, the low distributed roof load is 2.8 pounds per square foot. Snap together mounts dramatically lower labor costs and shorten project times for large rooftop solar installations. This minimizes business disruption and makes moving the system for future roofing, retrofit or ownership changes a simple process. Watch Video

A Unique Application for Agricultural Greenhouses
Solyndra offers a solar application for agricultural greenhouse and shade structures that takes advantage of the ability of light to pass through Solyndra’s proven solar panel design. Installation of Solyndra’s unique solar panels on agricultural structures allows for dual use of land, and reliably supports existing agricultural practices, while generating considerable electricity. The Solyndra solution enhances plant growth by controlling shading and provides growers with an additional income stream and power for their operations. Research by renowned agricultural establishments, such as CeRSAA in Italy and the Department of Plant Sciences, University of California Davis, USA, has confirmed the superior nature of the panel design and their ability to support crop growth underneath while generating electricity.
Greenhouse manufacturers can easily integrate Solyndra panels onto the roof of a greenhouse or shade structure. Complete coverage with Solyndra panels maximizes energy output per acre and generates a uniform shading comparable to the light transferred through conventional shade structures or the process known as whitewashing. The cylindrical design of the modules enables them to capture sunlight and generate electricity from direct, diffuse and reflected light. Growers with Solyndra-enhanced greenhouses may add an optional shade cloth to protect plants that require more shade during certain months of the year. Using a white cloth also allows some of the light to reflect back onto the tubes thereby increasing the energy output of the system. A venting system at the gables can also be used, since air circulation is important for plant health.
“This product, which supports plant growth and provides both shade and a distributed power source is the best idea I have seen for what could ultimately be the ideal application of solar power – dual purpose agricultural-land use,” says Dr. Giovanni Minuto of CERSAA, a research center in Albenga, Italy, who has been evaluating the Solyndra system over the past year with a variety of plant types and under various weather conditions.
Test sites at prestigious agricultural research establishments like CeRSAA and the Department of Plant Sciences, University of California, Davis, have demonstrated that plants, such as nursery crops and ornamental flowers grow well in the partial shading provided by Solyndra systems.
While the use of Solyndra panels on agricultural greenhouses is relatively new, Solyndra solar panel technology has been proven in installations on more than 1000 commercial and industrial rooftops around the world. Panels come with mounting solutions and cable management systems, which are then integrated into greenhouse structures by leading manufacturers in Italy. Currently, multiple megawatts of agricultural installations are underway. Solyndra also offers a solution for the rooftops of large, flat agricultural warehouses and distribution centers.
Solyndra is working with leading greenhouse manufacturers, EPCs (engineering, procurement, construction) and banks in Italy. Interested growers and agricultural cooperatives should contact Solyndra to be put in touch with an integrator in their area.
Cool, Powerful Roofs
Cool and Powerful Commercial Roofs
Building owners around the world are discovering the benefits of combining the power generation capabilities of a Solyndra solar power system with the energy conservation benefits of a white “cool roof”. Solyndra’s unique cylindrical solar modules are designed to capture additional refracted light from white roofs to raise the overall amount of electricity generated by the system. Albedo is the portion of light that is reflected from the roof and the more light reflected, the cooler the roof which is why building owners around the world are turning to white roofing membranes, or spray on white roof coatings. And while all solar systems perform better on white roofs due to lower ambient temperatures, Solyndra offers a number of additional advantages. Along with our non-penetrating mounting design and simple installation, one of the most important considerations in the United States are federal tax incentives that apply to both solar systems and the roof.

Cool Roofs Reduce Building Energy Needs
If you are considering a new roof, you should consider a white roof and a solar system on that roof at the same time. A cool roof reduces building cooling requirements by lowering the temperature of the roof and the building underneath. This means cooling equipment savings and in many cases the ability to run less air conditioning or purchase smaller air conditioning units.
You may even increase the life of your roof. By lowering the roof temperature, roofing products may last longer due to less thermal stress over time. Our non-penetrating design means less opportunity for leaks from your new roof.
While it makes great economic sense, a cool roof also makes an important statement about your commitment to reducing your building’s impact on the environment. One clear environment benefit comes as cool roofs reduce the “heat island” effect in cities, lowering average outside air temperatures. Lower the outside air temperature and you need even less cooling. In fact, U.S. Energy Secretary, Steven Chu said that “whitening the world’s roofs and roads would have the same effect on global warming as removing all the world’s cars for 11 years.”
Solyndra Solutions Providers have a wide range of specialized models and tools to help you understand the many factors involved in deciding if a cool roof and solar system are right for you and your business and we can help you find a roofing expert to discuss your reflective roofing needs.
