摘要:
A photovoltaic module (11) has a cathode (6b) and anode (6a) acting as electrodes for collecting an output power. When the photovoltaic module (11) is installed on a roof of a building for example, the cathode (6b) is located at a position higher than the anode (6a).

A tile (1) for attaching a solar battery module (6) to the roof of a house comprises a substantially rectangular plate-like tile body (2). The upper surface (1a) of the tile body (2) has a plurality of projecting portions (7) and a plurality of depressed portions (8) alternately extending over the entire length of the tile in a direction of inclination of the inclined roof. The upper surface (1a) of the tile body (2) also has a recess (4) formed therein for receiving the solar battery module (6). The recess (4) is formed by partially cutting out the projecting portions (7) of the tile body (2). Further, the recess (4) has a bottom portion (4a) to be brought into contact with the reverse surface of the solar battery module (6). The bottom portion (4a) is at a lower level than the projecting portions (7) and at a higher level than the depressed portions (8). The recess (4) also has a plurality of stop portions (4b) to be brought into contact with edge portions of the solar battery module (6) to hold them.
摘要:
A power generating system is integrated within an exterior shell or façade of a building structure. The energy generating devices (which can be photovoltaic), control units and associated power/signal wiring are incorporated and integrated within individual unitized curtain wall units making up the façade. Electrical power can be more advantageously generated from surface areas of building structures previously untapped for solar energy harvesting.

Provided is a mounting structure for mounting a film-shaped electric device (13) to a glass panel (2), comprising: a resin panel (11) attached to a surface of the film-shaped electric device to form a panel-shaped electric device (3) having first and second edges (3R, 3L); and first and second retaining members (4R, 4L) attached to one surface of the glass panel in correspondence with the first and second edges of the panel-shaped electric device, respectively, each first and second retaining member defining a groove (4a) such that the groove opens toward a region of the glass panel to be covered by the panel-shaped electric device, wherein the panel-shaped electric device is retained by the first and second retaining members with the first and second edges of the panel-shaped electric device being received in the corresponding grooves such that the surface of the film-shaped electric device having the resin panel attached thereto faces away from the glass panel.
摘要:
A space solar concentrator based on light-weight reflectors attached to the solar panel is described. The integration of the reflectors allows for a high modularity. Solar panel deployment is not perturbed by the reflectors even with two-dimensional deployment concept. Each reflector consists in small saw tooth aligned as rows 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-pointing occurs, the solar flux distribution is still the same on each cells. It guarantees a good electrical control and management on the whole panel. The reflector is preferably made of a thin film tight on a light-weight rigid frame deployed after launch. In another embodiment, the reflector is part of the panel substrate. The stowed configuration allows for superimposition of the solar panel. High reflectivity of the reflectors results from the use of vacuum deposited aluminum or preferentially over-protected silver.

There are provided a roof tile (1); a recess (2) formed in the roof tile to hold a solar cell module (6) furnished with a terminal box (7) on the back; and a recess (3) formed in the bottom of the recess (2) to hold the terminal box (7). The roof tile includes a sidewall (3b) with a cable hole (3a) toward the ridge of the roof. Output cables (8a, 8b) connected with the terminal box extend toward the ridge through the cable hole. Rainwater entering the recess (3) is hindered from reaching the terminal box and the cable connection (8c).
摘要:
A solar powered apparatus that includes a battery, at least one photovoltaic cell (which may be part of a solar module comprising multiple photovoltaic cells), and a DC-capable AC appliance, such as a compact fluorescent light. The solar powered apparatus may also include a first DC to DC converter that receives a first electrical signal from the at least one photovoltaic cell and provides a charging signal to the battery, and a second DC to DC converter that receives a second electrical signal from the battery and provides a DC power signal to the DC-capable AC appliance.

摘要:
Conventionally when the dial of an electronic watch is composed of a solar cell comprising a substrate and an amorphous silicon film on the substrate, the design of the dial is greatly restricted by the structure. According to the invention, the substrate constituting a solar cell has a light transmittance, and hence the solar cell cannot be seen. By using such a substrate as the dial or the windshield glass, a watch with a solar cell free from restriction on the design of the dial can be produced.
