About Us

With 50MW of Bifacial double glass panels installed or under completion, in sophisticated urban settings, we are spearheading the transformation of PV solar from a utilitarian function to artistic roof-top designs that add beauty to the function. Our symmetrical Bifacial glass panels are visually appealing even from the underside looking up, while delivering PV power at the highest levels. We have designed-in Quality that lasts. Overlaid upon this foundation, we deliver world class performance without cost penalty, from our proprietary thin-film Hybrid Cell Technology. And competitive Cost at the User interface, thanks to an intelligent lean manufacturing process. All driven by innovations that work, even at modest volumes.

Through application of advanced materials science, equipment engineering and SPC controls, we routinely achieve manufacturing yields over 99% with up to 6 sigma repeatability. Our modules deliver superior aesthetics, benchmark endurance against typhoons, hail storms and corrosive marine ambient; all with the coveted Class A fire certification.

Our modules provide over 22% effective efficiency, with ~15% bifacial boost from the back side. For consistent bifacial boost, in adverse non-uniform back lighting conditions, our modules with integrated optimizers for roof tops have gained rapid market recognition.

We achieve lower AC cost because of bifacial energy boost, smaller thermal coefficient and greater performance in low diffused light. Our lean manufacturing process helps by leveraging Moore’s law #2 as learnt by the LCD flat panel industry. And the frameless double glass panels at recommended tilt minimize the need for costly cleaning of dust or snow.

By positioning optimized Bifacial HCT products around the world, we are changing the status-quo:

Our Purpose

Our purpose is to commercialize world-wide, Sunpreme’s innovative Hybrid Cell Technology platform developed in our Silicon Valley USA R&D center. Packaged in Bifacial double glass frameless panels, this product line has the potential to become a world standard for premium solar PV products.

Our Carbon footprint can be 1/5 that for conventional diffused junction solar cells – thereby removing the current paradox of producing clean-tech products while locally polluting the environment.

Who We Are

Sunpreme is a six year old Company rapidly transitioning from a start-up to a growth phase global enterprise. Our R&D Center is located in Sunnyvale, CA to drive a constant stream of technology innovations for a multi-generational roadmap. We also have a fully functional, state-of-the-art integrated HCT cell production line in Jiaxing, near Shanghai in China. These cells are packaged in thin- profile double glass panels which have been successfully deployed in 24 countries around the world.

Vision & Values

Be a model global enterprise in the clean energy eco-system.

Our Values are world-class customer-centric Innovation, Global reach, and Lean teamwork.


To grow a global business around our green SmartSilicon® solar technology with a game-changing Moore’s law driven cost-performance leadership, thereby making a major impact on the clean energy eco-system.

Market Recognition Drives Premium Demand

Sunpreme’s GxB 310 S M was selected as one of the finalists for the 2016 InterSolar award in Munich. It was recognized for developing a “bifacial solar module integrated with an optimizer in an efficient design, allowing it to perform in adverse ambient conditions”.

In its 2015 annual report, updated October 2016, Fraunhofer ISE ranked Sunpreme among the top three providers of highest efficiency commercial PV modules, ahead of Panasonic and LG.

In the latest Principal Solar Institute (PSI) ratings for Thin Film PV modules, Sunpreme appears in 7 out of top 10 rankings, along side Panasonic, and significantly ahead of traditional thin-film providers such as First Solar and Solar Frontier. (http://www.principalsolarinstitute.org/uploads/


Our superordinate goal is to deliver, for outstanding customer and investor value, leading edge Solar PV Solutions.

Our innovation portfolio runs the gamut, from basic materials to device to modules and systems – all aimed at achieving the toughest panels in the industry with superior aesthetics and a significantly greater power density. Our PV panels have been deployed in climates ranging from desert heat to Antarctic cold to island hurricane country, from hazy sunlight in hot, humid environments of China and India to balmy California skies.

Our panel costs/W are significantly lower than those for traditional high performing premium panels, and we have a cost roadmap that gets us down to commodity level costs. We do this by leveraging proven Moore’s Law principles already established for the LCD display industry. The incumbents, despite superlative efficiencies, have a higher cost structure due to complex process sequences on smaller size wafers, and a high CAPEX intensity, which discourage continued growth investments.

Moreover, we have or are establishing integration partners in major distributed power segments. Our integrated low cost, total solution coupled with development partners sets us up favorably to become a profitable growth Company in the clean-tech space, with a sustainable competitive advantage.

Moore's Law for Solar PV

For over 40 years, Moore’s law for semiconductor chips has driven unprecedented improvements in chip performance as well as unit cost per transistor.

The only industry which has come close in recent times is the flat panel LCD (Liquid Crystal Display) TV industry where the glass sizes have increased from Gen 5 to Gen 6 to Gen 8 to Gen 10. The results are reflected in widespread affordability of LCD TV’s around the world.

Thanks to our reuse of thin film equipment technology from FPD-LCD industry, we are able to invoke the Moore’s law of stepped cost reductions – for the first time in the PV industry. The glass panel is replaced with a wafer tray of similar dimension and weight, so that we hold 100 156mm cells per Gen6 tray.
