How it started

Market history

Ascent Solar entered the manufacturing stage for its products in 2013, in part by teaming up with a range of other companies like TFG Radiant (for integrating these materials into a range of building and construction materials), Foxconn (for a "pilot project" at the Zhengzhou factory, which was then manufacturing the iPhone 5), and Bye Aerospace (for solar-powered unmanned aircraft).

Consumer products

In June 2012 Ascent Solar launched the EnerPlex consumer brand and their first product, a solar power enabled phone case for iPhone 4. In October 2013 the company expanded beyond phone chargers and introduced the Packr solar enabled backpack.

In October 2016 the Association of Marketing & Communication Professionals (AMCP) recognized the EnerPlex brand with 3 MARCOM awards for excellence in retail marketing.

On February 27, 2017, Ascent Solar announced that it had sold the EnerPlex brand and all related non-solar intellectual property rights to Hong Kong–based Sun Pleasure Co. Ltd in order to "focus on its core strength in the high-value specialty PV market".
