A solar shed is disclosed comprising a secure shelter for battery-powered electric tools, such as lawnmowers, trimmers, and leaf blowers, and further comprising photovoltaic cells built into the sloped roof of the solar shed. The electricity generated by the photovoltaic cells is routed to the batteries of the electric tools in the interior, so that the batteries are recharged for later use. The solar sheld is marketed in prefabricated components, having a square floor plan so that the walls and...

A carousel powered by an arrangement of photoelectric solar panels is driven by an electric motor, which is connected through a battery to an arrangement of solar cells located on the roof of the carousel. Also connected to the battery, in parallel with the motor, are a number of decorative bulbs, to prevent overcharging of the battery. The solar panels are hinged and are placed on the roof of the carousel with one part of the panel horizontal to the ground, and the other part angled upwards, to...

A solar panel includes: a rectangular space frame constructed from timber members 1a, 1b, 1c and 1d; a sheet of plasterboard 2 beneath the timber frame; a foil backing 3 on the plasterboard; and a shaped bed 4 made of polyurethane foam which is moulded into position in the housing constituted by the timber frame and the sheet of plasterboard 2, and which adheres in an air-tight manner to the housing. A foil cover 5 is provided on top of the shaped bed 4. Above the foil cover 5 is a solar radiati...

A solar collector includes a collector body having a substantially curved collector surface. A reflective device projects from the collector body and reflects incident solar energy to the collector surface. The collector body is substantially conical and the reflective device is secured to and projects externally from the conical collector body. The reflective device has a curved surface which extends along an arc of a circle and which overlies the collector surface for reflecting incident solar...

A solar collector has a distribution and collecting unit having a housing and a distribution channel and a connecting channel arranged in the housing. Collector tubes for heating a fluid medium are connected to the housing. The collector tubes have an adaptor, respectively, with a rotary closure for connecting the collector tubes to the distribution channel and the collecting channel of the housing. The adaptor is rotatably adjustable for aligning the collector tubes relative to the solar radiat...

A diode-incorporated solar battery, which is intended to minimize an increase in production cost and a decrease in reliability that are involved in incorporating diodes into the solar battery, and to reduce the area of the surface electrodes of the solar battery so as to increase the electric power generation of the solar battery, wherein to this end, a connecting metal fixture for interconnecting solar cells has added thereto projection for parallel-connecting the solar cells and diodes.

A space solar concentrator based on light-weight reflectors (3) attached to a honeycomb panel (1) is described. The integration of the reflectors (3) allows for a high modularity. Solar panel deployment is not perturbed by the reflectors (3) even with two-dimensional deployment concept. Each reflector (3) consists in small saw tooth aligned as rows (2) with solar cell rows in between. Low concentration is achieved with a high level of thermal control and a high optical efficiency. When small off...
