OUR TEAM


Barry Sgarrella
CEO of Marin Developers, LLC & SolAgra Corporation

Barry Sgarrella is a third-generation land developer, licensed general contractor and inventor.  He "grew up in the development and construction business".  He was educated in Civil (Structural) Engineering at the University of Florida, specializing in computerized analysis of structural systems.  U of F was followed by Johns Hopkins University, Applied Physics Lab (“APL”) where he led a coding team that developed the Navy Navigational Satellite System – a satellite navigation system which was the precursor to GPS.  Following APL, he took his place in the family development/ construction business and expanded his development and construction management experience and knowledge.  ​

To expand his experience in commercial construction, he left the family business to work for a commercial general contractor.  Over the next 5 years, he built two general hospitals in the Washington, D.C. region - one in Fairfax, Virginia, the second in Prince Georges County, Maryland.  To increase his knowledge in heavy construction, he worked for the Gordon H. Ball Division of Dillingham Construction building 4 underground subway stations and 6 miles of hard rock tunnels on the Washington, D.C. Metro System.  Two of the largest projects built on that system.

Moving to California, in 1978, he worked for Rigging International and developed a patented hinge-up dome design that was built throughout the United States and as far as Chuquicamata, Chile.  Upon completion, that project in the Chilean Andes was the largest dome in the Southern Hemisphere. 

He opened his own land development and construction firms in 1984.  He has developed successful residential and commercial projects in California ever since.  After enjoying the boating and recreational opportunities in the California Delta, in 1987 he bought a home on Twitchell Island.  That home had a small wind turbine, and it began a fascination and appreciation of renewable energy systems. Since 2005 he has been a Trustee and President of the Twitchell Island Levee District (Reclamation District 1601) and has become familiar with the many issues and benefits of living and working on Delta islands and providing the environmental stewardship that maintains this delicate eco-system in balance.

He formed SolAgra Corporation in 2013 to develop solar technologies that could help solve California’s continuing drought problems - pioneering the SolAgra® Water Solution™ and SolAgra® Farming™.   He used the hinge-up concepts of the dome construction to develop the operational facets and efficient erection procedures of the SolAgra Farming Arrays. Details of both concepts are available on this website.
