Abstract: A vehicle-top solar-power generator has a Photovoltaic frame (2) with mounting brackets (3) that are positioned on a top (4) of a vehicle (5) with a cooling space between the top of the vehicle and the photovoltaic frame. At least one and preferably a plurality of Photovoltaic panels (1) are positioned in the Photovoltaic frame and covered with a light-transmittable material (28) such as plexiglass or a screen of suitable material. Direct current generated from the Photovoltaic panels is transmitted to a primary battery (6), to a secondary battery (7), to AC electrical items (13) and to DC electrical items (14). Power generated in excess of needs for the vehicle is inverted to alternating current for electrical items in such structures (15) as a home, workplace, recreational vehicle, boat or other structure near the vehicle. A cooling fan (12) powered by current from the Photovoltaic panels is used to cool the Photovoltaic panels.
