A combination roofing panel and solar module includes a flexible membrane sheet, such as a single-ply membrane sheet, and a plurality of elongated solar or photovoltaic modules arranged side-by-side, end-to-end, or adjacent each other. The modules are adhered to the flexible membrane, and the edges of the modules having electrical connectors or electrodes are arranged to face each other or be aligned with each other. The electrical connectors are connected by a solder connection to module electrodes through apertures in a bottom surface of the flexible membrane and are connected in series. The series electrical connectors are connected directly to direct current (DC) electric devices, to a combiner box, to another panel or to an inverter which coverts direct current (DC) to alternating current electricity for use in residential, commercial or industrial building structures. The ends and elongated edges of a roofing component or panel having the flexible membrane and modules can be sealed for protection.
