## About

Based in West Sussex, UK, and founded in 2009 by its CEO Christophe Williams, Naked Energy Ltd. operates as a manufacturer of hybrid solar collector Virtu that combines engineering and sustainability to decarbonize heat and generates power. In August 2026, Naked Energy Ltd. raised GBP 8.875 million in venture funding led by Great British Energy, with participation from Barclays Climate Ventures.

Naked Energy Ltd. offers Virtu Hot, a solar thermal collector that heats water from the power of the sun; Virtu Pvt, a hybrid solar collector that combines solar photovoltaics (PV) and solar thermal technology, to generate both electricity and heat from a single solar collector.
