"You need to speak to several contractors before making a final selection," said Michael Trahan, a solar energy expert.

Rethinking module geometry beyond the traditional rectangle could increase rooftop PV capacity on irregular buildings by improving packing efficiency and expanding placement options.

Rethinking solar panel geometry beyond the traditional rectangle can unlock significant energy potential by optimizing coverage on complex, irregular rooflines.

Germany’s SolarEnvelopeCenter project has launched a web-based planning guide for building-integrated photovoltaics (BIPV), offering standardized design solutions for roofs and facades that comply ...
