Dow Chemical Co. will stop manufacturing its Powerhouse modules at its Midland plant.

According to a letter being sent to builders dated June 28, Dow is going to accept orders for its "Powerhouse Solar System 2.0" through July 28. All shipments will be made by Aug. 10, according to the letter. All warranties on existing systems remain in effect.

"We will work with you to determine the path forward to meet your product needs during this period," reads the letter, which was signed by Craig Brown, global business director for Dow Solar products and services.

Dow's Powerhouse Solar Shingle launched in the U.S. in October 2011.

A spokesperson from Dow states:

"Aligned to its strategy to go narrower and deeper in key markets such as Packaging, Transportation and Infrastructure, and in conjunction with Dow’s recent integration of Dow Corning’s technology portfolio, Dow recently announced it will transition its POWERHOUSE platform to a licensing business model, with a focus on driving growth in the global photovoltaic market."

"The recent acquisition of Dow Corning’s expertise in solar market applications, coupled with the clear shift in cost structure and demand dynamics for building integrated photovoltaic market applications in the North American residential housing sector, led Dow to re-evaluate the long-term competitiveness of its POWERHOUSE platform in commoditizing solar applications. As a result, the Company will cease the manufacture of the building-integrated photovoltaic solar modules at its Michigan and California facilities, and transition to a licensing business model. Dow will retain the technology expertise for the platform, and will leverage Dow Corning’s experience and expertise in solar market applications, cost structure and market outlook to identify valuable global photovoltaic market opportunities for these technologies."
