Morgan Solar

Series A in 2010
Morgan Solar Inc began with a mission in 2007 – to develop highly efficient, low cost solar technology. Until now, all the real advancements in solar power always seem to be “10 years away”. John Paul Morgan, a Physics Engineer, with a background in optics, medical imaging and photovoltaics, developed an idea to make solar energy more affordable. His idea was to design an optical concentration system that would elegantly solve many of the problems of existing CPV systems. There first product to market, the Sun Simba HCPV, is designed for solar farm applications. Demonstration and test installations will begin in 2009, and our first commercial systems will be available in early 2010. The second set of products, the Sun Stream Window and the Sun Block Panel, are designed for building applications and smaller scale demonstration and test systems are also scheduled for 2009, with sales begining sometime after mid 2010.
