David Matthews, chief executive of the Solar Trade Association, said it was essential to look carefully at where problems might arise to maintain confidence in the technology. There have been no legionella cases yet linked to solar in the UK.
He argued that issues identified within solar systems should not be used to try to address wider national issues with legionella in residential properties.
Some reports have indicated that 10 to 15 per cent of all homes are at risk.
He said: “We mustn’t use new technology to manage the legionella issue. If we have a legionella issue we must deal with it directly. The solar industry will fight any attempt to piggy-back changing all the domestic homes in the UK on the back of the solar industry. That is something we find unacceptable.”
STA will work with the Department for the Environment, Food and Rural Affairs, the Hot Water Association, the Water Regulations Advisory Scheme and Bsria on the risk assessment.
