An automatic darkening filter with adaptive parameter adjustment includes: a welding arc intensity detection unit configured to provide a first signal for determining the welding arc intensity; a solar power supply module configured to provide electric energy for the welding arc intensity detection unit and provide a second signal for determining the ambient light intensity; and a CPU and a light valve, the CPU being configured to calculate a difference between the welding arc intensity and the ambient light intensity based on the first and second signals, and control the scale number of the light valve based on the difference. The automatic darkening filter can realize the automatic adjustment of the scale number, and in the adjustment process, the welding arc intensity signal can be revised based on the ambient light intensity, which can effectively ensure the accuracy of the final determination of the scale number.

A moldable photovoltaic module is provided. The module includes a flexible polymeric flex-circuit substrate having an electrically conductive printed wiring pattern and solder pads defined on it. Small photovoltaic cells are affixed to the flex-circuit substrate by back-surface contacts in electrical contact with the solder pads. At least one thermoformable polymeric film is joined to the flex-circuit substrate. Each said solder pad comprises a solder composition that, after an initial melt, has a melting point that lies above at least a portion of the temperature range for thermoforming the polymeric film.

A deployable/retractable structure, or a template thereof, is disclosed. The structure comprises a plurality of pleating folds among peaks and valleys, which extend away, retract towards, and/or rotate around a central hub. The folds, with extended continuous planar surfaces, can be configured to host objects, such as solar arrays. In a retracted configuration, solar arrays are protected and folded away, taking up much less space. Electricity generated via the arrays is coupled with signals to instruct the structure to transition among stages of retractions and/or deployments. This structural design enables the solar arrays to be positioned in many angles and facets, which makes it an overall non-flat unit, less dependent on the directions of sunlight. A smaller scaled down unit can be light, portable, and operated by hand. A larger scaled up unit can be stationed on the ground or atop existing charging stations, which affords easier access and maintenance.

A modular power supply apparatus for use in harsh climates that comprises a portable, low cost, easily maintained, durable power supply for energy production as well as systems, methods for forming, and methods of using same.

A solar powered outlet assembly includes a housing that has a spike to penetrate a support surface thereby retaining the housing on the support surface. A pair of female electrical outlets is each integrated into the housing to have a male power cord plugged into the female electrical outlets. A solar panel is coupled to the housing such that the solar panel is exposed to sunlight. The solar panel is in electrical communication with each of the female electrical outlets. In this way the solar panel can supply electrical power to the male power cord that is plugged into the female electrical outlets.
