In 1965 at the age of 11, Larry manufactured a photovoltaic cell through a Bell Telephone Lab school program in San Diego, CA. Starting with a raw silicon ingot and after weeks of preparation phases, the polished and doped pie shaped quarter silicon wafer produced about 0.5 DC volts in full sunlight. It worked perfectly converting sunlight into electricity and was a brilliant success. As a consequence, Larry was already convinced of the efficacy of solar electricity four plus decades ago as an elementary school student.

After graduating from UC Berkeley, he attended Dr. Marshall Merriamís UC Solar Engineering graduate seminars. He went to work at Solar Station, Inc., designing and installing solar thermal systems in the 70ís and 80ís. He supervised all phases of the design and installation of the UC Berkeley Student Co-op solar thermal systems, that are still working today.

US Federal Solar Tax Credits were reinstated in 2005. On Kathleenís insistence, Larry installed solar photovoltaic modules on their home and office. It felt great to be working with solar again.

Larry re-entered the solar field selling, designing, and installing solar. With long-time associate Paul Cooper, Kathleen and Larry founded A1 Sun, Inc. in 2007.

"A1 Sun, we build solar to last."
