The invention relates to a device and a method for controlling the power supply of a field device (100). The device comprises a rechargeable energy storage device (140), a load (160), and a first switch (144) between the energy storage device (140) and the load (160). Furthermore, the device comprises a solar cell (120) with a cover (121) configured to block light from entering the solar cell (120), thereby switching the field device (100) from normal operation to shipping mode and opening the first switch (144).

The utility model discloses a foldable solar project lamp which comprises a lamp body and a solar cover plate, an installation groove is formed in the top of the lamp body and provided with a connecting portion of a hollow structure, a solar panel is arranged at the bottom of the solar cover plate, and a pair of hinge portions is arranged on the side, corresponding to the connecting portion, of the solar cover plate. A hinge groove is formed between the hinge portions, the hinge groove is arranged on the outer side of the connecting portion in a sleeved mode, a hinge component is arranged in each hinge portion, one end of each hinge component is inserted into the corresponding connecting portion, and the solar cover plate and the lamp body are hinged through the hinge components. The solar cover plate and the lamp body are overturned and folded with the hinge component as the axis, reflected light can be reduced through adjustment of the orientation angle of the solar cover plate, more light enters a solar cell, the overall light absorption and utilization efficiency is improved, and in the transportation process, the transportation efficiency is improved. And the solar cover plate is folded to be stored in the mounting groove of the lamp body, so that the occupied space can be greatly reduced, and the transportation cost is reduced.

The application discloses a solar energy coupled biomass gasification and chemical chain combustion SOFC combined cooling, heat and power system in the technical field of distributed energy, which comprises a solar energy assisted biomass gasification subsystem, an SOFC power generation subsystem, a supercritical carbon dioxide power cycle subsystem, a chemical chain combustion subsystem and a refrigeration and heat supply subsystem; the system collects solar energy, and the gasification agent, biomass and the gasification agent are reacted to generate synthetic gas for the SOFC power generation subsystem to generate power; the SOFC anode tail gas enters the chemical chain combustion subsystem to perform flameless oxidation and release heat, the high-grade heat released drives the supercritical carbon dioxide power cycle subsystem to perform cascade power generation, and the remaining low-grade waste heat is recycled by the refrigeration and heat supply subsystem to realize the collaborative output of cold, heat and power. The application improves the comprehensive energy efficiency of the system through multi-energy complementation and energy cascade utilization, and realizes carbon dioxide enrichment in the chemical chain combustion subsystem.

Methods and systems are disclosed for automatically determining solar access values, including a method including calculating a ray between a sun position and a structure vertex at a plurality of time periods; comparing a path of the ray to location of points in object point cloud data representative of the size, shape, and location of one or more objects to determine that the object(s) blocks the ray from reaching the vertex, resulting in a shadow over the vertex for at least one of the time periods; determining effects of the shadow over the vertex on the maximum possible irradiance values based on a determined distance and whether the vertex is within an umbra, penumbra, or antumbra of the shadow at at least one of the time periods; and determining irradiance in Watts per time period over the plurality of time periods in which the shadow is over the vertex.

The present invention provides an inspection device for solar cell modules that is the same color as or similar to the majority of the solar cell and can detect foreign matter that has entered between the solar cell and the sealing glass. [Solution] A solar cell module comprising a sealing glass, a sealing member, and a solar cell sandwiched between the sealing glass and the sealing member, is used to detect foreign objects that are the same color as or similar in color to most of the solar cell between the sealing glass and the solar cell, and comprises an imaging unit, an illumination unit that irradiates the irradiated portion of the solar cell through the sealing glass with illumination light having a maximum peak in the wavelength range of over 380 nm and up to 430 nm from a direction inclined with respect to the imaging axis of the imaging unit, and a foreign object detection unit that receives reflected light from the irradiated portion and detects foreign objects based on the image captured by the imaging unit, wherein the solar cell has a reflectance of 5% or more of the illumination light and a reflectance greater than that of the foreign object.
