Solartwin was developed Scottish scientist Kerr MacGregor at Napier University, Edinburgh. The Solartwin system was first installed on properties in the UK in 1998 and now thousands have been installed Worldwide.

A single Solartwin Panel heats enough hot water for between 1-4 people, this is ideal for a typical UK household. A Solartwin domestic solar thermal installation is usually completed in a single day. One Solartwin solar panel typically heats a normal 120 litre hot water cylinder to 50-60C on a sunny March or Sept. day (60-80C in summer). Independently tested, a Solartwin solar heating system delivered 1000 kWh (3.6 GJ) of clean green energy as solar hot water a year in UK. It saves far more bought-in energy.
