Solar panels are one of the least cost-effective ways of combating climate change and will take 100 years to pay back their installation costs, the Royal Institution of Chartered Surveyors (Rics) warned yesterday. In a new guide on energy efficiency, Rics said that roof panels for heating water and generating power are unlikely to save enough from bills to make them financially viable in a householder's lifetime. In the case of solar panels to heat water for baths and showers, the institution estimates the payback time from money saved from electricity and gas bills will take more than 100 years - and up to 166 years in the worst case.Photovoltaic (PV) panels for power - and domestic, mast-mounted wind turbines - will take between 50 and 100 years to pay back.
