LCE has been founded in 2008 by Dr. Oliver Lang in Berlin as engineering and consulting office. The main working fields of LCE are autarkic, stand-alone solar power supply systems and devices and LED lighting systems in the power range from miniaturized Energy Harvesting systems up to large power supplies for houses or industrial applications.
Many customers and projects of LCE are from countries within the "sun belt", such as African countries or South China. Other projects such as technology consulting of solar module companies or engineering of energy harvesting systems are mainly running in European countries. LCE is also supplying components of PV and LED systems, as actually the complete solar power supply for golf carts in a southern African state.
