From Outer Space Into the Home — Sharp’s Solar Power Technology Helps Achieve a Brighter Future

History of Sharp’s solar cell development

Sharp began its involvement with research and development of photovoltaics in 1959. Since then, Sharp solar cells and peripheral products have been improved and applied to a wide range of applications: from satellites out in space to terrestrial purposes for lighthouses, industrial applications, and residential use.

History of Sharp Solar
