(57) ABSTRACT A solar panel may include a first multi-cell thin-film photo Voltaic module of a first fabrication type including a transpar ent Support forming a front Surface of the panel, a first pair of connection terminals on the transparent Support, and first cells of a certain area, being on the transparent Support, and being connected in series to the first pair of connection ter minals. The solar panel may include a second multi-cell thin film photovoltaic module of a second fabrication type com prising a Support forming a rear Surface of the panel, a second pair of connection terminals on the Support, and second cells of a certain area, being on the Support, and being connected in series to the second pair of connection terminals. The Solar panel may further include a pair of panel terminals for con necting the Solar panel to an external circuit, the first and second pairs of connection terminals being connected either in …
