Multiple reports claim that fires involving domestic solar panels are increasing. The articles state that solar panels are linked to more than 170 house fires per year, and that fire brigades are being called to incidents involving solar panels on average once every two days. The reporting frames this as a growing risk associated with rooftop solar installations, and indicates the issue is drawing increasing attention from emergency services. The coverage also suggests the number of incidents could continue to rise, though specific projections and underlying sources are not detailed in the provided text. Overall, the outlets agree on the central figures: a yearly count of incidents above 170 and an average frequency for emergency response of about every two days. The articles present these points as evidence of a trend rather than isolated events.
