Correct. And also the non-solar panel material. For example the aluminium support they use between the roof and the solar panels costs the same or more than the actual solar panels. When I asked for an offer two years ago the price of the solar panels was about 25% of the total cost. The aluminium frame was 25%, labor 30% and putting up the scaffold 20%. I hope thin film solar panels integrated in the actual roof material will become more common going forward as it removes the need for an aluminium frame, you get a new fresh roof, it's lighter, no holes are drilled in the roof etc.
