Naked Energy has developed VirtuPVT, a hybrid solar technology that generates both heat and power resulting in a higher energy density than alternative solar technologies. VirtuPVT can deliver a peak efficiency of 80%, converting 20% of the sun’s energy to electricity and 60% as heat. VirtuHOT is a complementary high temperature thermal only collector. 

Naked Energy’s patented technology is ideally suited for use on flat roofs in urban environments where space is limited. This includes large commercial users of thermal energy such as hotels, hospitals and apartments, as well as manufacturing processes that need hot water and/or heat, including district heating and cooling.

Notable Achievements

  • Winner of the 2021 CIBSE Building Performance Award.
  • Set up second production facility in the UK and secured distributors in the U.S., South Africa and Australia.
  • Generating revenues and positive gross margins with proven technology and flagship projects secured.

Currently Operating in Five Regions
