There is one type of solar panel which will conform to shapes such as a 'Bow' roof. These panels are known as an amorphous photovoltaic panel.
- They are typically less efficient during short periods of time but begin producing amperage at low light levels (even under a full moon) allowing them to work longer durations of time.
- Installation of the amorphous panel must be on a standing seam metal roof since they are a peal and stick application.
Photovoltaic shingles are rigid panels made to look like shingles and are designed to be installed on a even, straight surface such as a gable roof and cannot be bent to lay flat on a roof such as yours.
However in the past amorphous shingle photovoltaic panels were developed and manufactured. The leading manufacturer of amorphous photovoltaic panels, Uni-Solar Ovonic, filed for bankruptcy a few years ago and were divided and bought out.
An alternative to trying to install the panels on the roof would be to install a rack or pole mounted photovoltaic system at ground level if space and the proper solar envelope is available.
