A typical domestic Solar Thermal installation will weigh in at around 50kg 70kg. Most roofs are designed and built to withstand extra weight caused by snow and rainwater. In comparison to the weight of the roofing materials the extra weight of the Panels is nominal. Generally if the roof is in good condition there is no requirement to strengthen it, prior to mounting solar panels.
