A solar panel is disclosed that can be daisy-chained with other solar panels. The solar panel automatically generates output alternative current (AC) power that is in parallel with input AC power coming into the solar panel when the solar panel senses the input AC power so that the solar panel operates as a slave in this state. The solar panel automatically generates standalone AC output power when the solar panel fails to detect input AC power coming into the solar panel where the solar panel operates as a master in this state. The solar panel generates the standalone output AC power without any reliance on input AC power generated by a utility grid and/or other AC power sources external to the solar panel.

The present invention is a desiccant system for controlling moisture in a solar collector. The desiccant system has a desiccant bed enclosed within a housing, and is thermally coupled to the solar collector as well as being fluidly coupled to it through an orifice. Waste heat from the solar collector is conducted to the desiccant system and is used to regenerate the desiccant bed. The desiccant system includes moisture barriers which cause moisture from the desiccant to preferentially be released to the external environment rather than entering the solar collector.

A solar collector panel is disclosed for heating of air, in which the conventional insulation material on the back panel facing away from the sun is replaced by a spacing between a permeable back panel and a permeable heat absorber means, so that a heat convection airflow through the back panel and into the interior of the solar energy panel against the temperature gradient prevents the convection heat loss in the opposite direction. The back panel also reduces the radiation heat loss from the heat absorber means. Furthermore, in case the flow of air through the solar energy panel is stopped, the convection-insulation will no longer be effective, and a photovoltaic cell panel placed within the solar energy panel and generating electricity from the solar radiation will not be subjected to the damaging high stagnation temperature of a traditionally insulated solar collector panel.

System for providing a secure file service includes an MLS file service module (300) comprised of a cryptographic processor (302). The MLS file service module also includes an MLS file system (301) hosted by the cryptographic processor. A secure user processor (402) includes programming and communications hardware for requesting at least one classified file from the MLS file service module. The cryptographic processor includes cryptographic hardware and software to decrypt the classified file. The cryptographic processor is also performs an integrity check on the classified file. Once the file is decrypted and its integrity checked by the cryptographic processor, the MLS file service module serves the classified file to the secure user processor in decrypted form. If the classified file is an executable file, the method also includes selectively enabling a write function for program memory of the secure user processor. This write function is disabled immediately after the classified executable file has been loaded into the program memory to guard against self modifying programs.

An extrapolation system includes acquiring a first orientation-referenced image at a first position, acquiring a second orientation-referenced image at a second position having a vertical offset from the first position, and processing the first orientation-referenced image and the second orientation-referenced image to provide an output parameter extrapolated to a third position that has an offset from the first position and the second position.

The invention relates to a solar tube cleaning device and belongs to the field of mechanical cleaning. The solar tube cleaning device is composed of a solar tube transmission device and a cleaning device. A motor drives a planar slot type cam to rotate, and a cylindrical bump is driven by the rotation of the cam to move down to drive a solar tube in an insertion slot to slide down. During working, a hairbrush of the cleaning device is enabled to be matched with the solar tube transmitted by the insertion slot, and the positions of the hairbrush and the solar tube are fixed. An inner hairbrush enters the inner part of the solar tube and conveys descaling fluid at the same time, and an outer hairbrush covers the outer ring of the solar tube to clean the surface of the solar tube. The solar tube cleaning device has the beneficial effects that the transmission device is relatively slow in running and high in stability; the hairbrush of the cleaning device is designed into an inner layer and an outer layer, which efficiently clean the inner surface and the outer surface of the solar tube simultaneously; the inner brush is hollow and can convey the descaling fluid for the solar tube.

A solar panel is disclosed that generates standalone alternative current (AC) output power where the standalone output AC power is generated from direct current (DC) power stored in a battery bank included in the solar panel. The solar panel generates the standalone output AC power without reliance on input AC power generated by a utility grid and/or other AC power sources external to the solar panel. The solar panel automatically generates the standalone AC output power when the solar panel fails to detect input AC power coming into the solar panel where the solar panel operates as a master in this state. The solar panel automatically terminates the generation of the standalone AC power when the solar panel detects input AC power coming into the solar panel where the solar panel operates as a slave in this state.

A solar cell module of the present invention is provided with a reflector that reflects incident light to a solar cell, and a reflecting surface of the reflector is in a concave-convex shape. The reflector is constructed with a diffuse reflective material that diffusely reflects light. Some of sunlight that enters the solar cell module hits a front surface of the solar cell, and the rest passes through a gap between the solar cells and then enters the diffuse reflector. The sunlight that enters the diffuse reflector is diffusely reflected, and thus an amount of light that enters a back surface of the solar cell increases. Thereby, the solar cell module can increase power generation efficiency.
