$RGSE Engages Supply Chain Manufacturing Partners for Launch of RGS POWERHOUSE™

DENVER, April 16, 2018 — RGS Energy (NASDAQ:RGSE), America’s Original Solar Company since 1978, has partnered with industry leaders Risen Energy Co., General Polymers Thermoplastic Materials and Creative Liquid Coatings to commercialize the RGS POWERHOUSE™ 3.0 Solar Shingle, an innovative and visually stunning solar shingle system using technology developed by The Dow Chemical Company.

Next Generation POWERHOUSE™ 3.0
By coupling roofing with an energy saving solar panel in a singular product, the POWERHOUSE™ Solar Shingle uniquely addresses the unmet needs of residential homeowners with asphalt rooftops, which represent about 85 percent of U.S. homes. Currently, more than 1,000 homeowners are enjoying benefits of earlier generations of POWERHOUSE™.

RGS Energy believes POWERHOUSE™ addresses a large, untapped market, appealing to both single-family homeowners and new home builders. The forthcoming POWERHOUSE™ 3.0 is designed to maintain or improve upon earlier generation product features, while substantially reducing manufacturing costs. POWERHOUSE™ 3.0 will offer a more competitive value proposition, even after the recently imposed tariff on imported solar cells.

RGS Energy estimates if POWERHOUSE™ achieves a 1% share of the re-roof and new home build markets, the product could be propelled to the billion-dollar revenue mark.

Risen Energy Co.

Risen Energy Co., Ltd (China – Shenzhen: 300118) is a Top 10 Tier 1 solar cell and module manufacturer located in China with a current annual manufacturing capacity of more than 4.5 gigawatts. Risen will supply all the solar components and wire harness connectors for POWERHOUSE™ 3.0.

“We’re excited to be a part of this new POWERHOUSE™ 3.0 program,” said Bypina Veerraju Chaudary, Risen’s Chief Sales and Marketing Officer. “Built-in Photovoltaics are the path to greater world-wide adoption of solar technologies, and further enhances the clean energy choices for discerning consumers.”

General Polymers Thermoplastic Materials

General Polymers Thermoplastic Materials is one of the fastest growing multi-national thermoplastic resin distributors serving custom injection molders in North America. The company will supply the polypropylene plastic resin for the base assembly of POWERHOUSE™ 3.0, which is expected to maintain the durability and toughness of the original resin while increasing manufacturing efficiency and reducing the overall cost of raw materials.

“Building-Integrated Photovoltaics is an untapped market in the U.S., and RGS Energy, America’s Original Solar Company, is an ideal partner for General Polymers for pursuing this opportunity,” said Michael Kirtley, President and COO of General Polymers. “We are looking forward to being a strong channel supplier to their POWERHOUSE™ 3.0 program.”

Creative Liquid Coatings

Headquartered in Northeast Indiana, Creative Liquid Coatings provides world-class capabilities in injection molding and paint finishing serving the consumer and industrial products markets. The company will supply all POWERHOUSE™ 3.0 molded polymer components fully assembled, with all solar components, wire harnesses and other parts required to deliver a finished product to RGS Energy customers. Creative Liquid Coatings was a supplier for earlier generations of the POWERHOUSE™ product.

“RGS is the perfect company to commercialize POWERHOUSE™ solar shingles, and we are excited to join them in introducing the product to a broader market,” said Stephen Geist, General Manager of Creative Liquid Coatings. “POWERHOUSE™ is an innovative technology that we expect will play a critical role in the evolution of the U.S. residential roofing marketplace.”
