The Industry Ministry plans to announce an industrial standard for solar rooftop panels and related equipment within three months.
Industry Minister Varawut Silpa-archa said at Government House on Tuesday that he would accelerate the introduction of an industrial standard to ensure the safety of the increasing number of households switching to home solar power.
He planned to impose the new standard no later than September. 
He said the standard would apply to solar rooftop panels, direct-current circuit breakers, fuses and wiring for solar power systems, lithium batteries to store power from solar rooftops, combiner boxes and MC4 solar cable connectors.
“When the law takes effect, all solar panels available in Thailand will have to pass tests set by the Thai Industrial Standards Institute, to ensure they are safe and pose no fire risk or other danger to people’s lives and property,” Mr Varawut said.
