One of the fundamental problems and drawbacks of existing soldering devices, including electric irons, is the consumption of 60% of the electrical energy, low performance speed and efficiency, and short lifespan. This is because in these devices, a considerable amount of energy and time is only spent on preparing and heating up the soldering device, even during the periods when the electric iron is not in use in the soldering process. Therefore, the process should be kept active during the operation, which leads to a significant increase in energy consumption and a decrease in the lifespan of the soldering device. Additionally, there is no possibility of multi-purpose usage or exploiting the device in areas where there is no access to city electricity. Using non-consumable electrodes and hybrid solar energy with AC/DC currents, a device has been created that performs three soldering processes of hard, soft, and cutting for all materials up to a melting temperature of 1100 degrees Celsius instantly. The photovoltaic panel absorbs 100 watts of solar energy and converts it into electricity, which is stored in a 12-volt electrical source. By increasing the current intensity through a non-consumable carbon electrode, it is used to perform the melting and cutting soldering processes. The design of this device allows us to use three sources of solar energy, AC city electricity, and DC electricity produced by a car. Its use in various conditions, including areas without city electricity, has become possible.

One of the fundamental problems and drawbacks of existing collectors is the inability to simultaneously produce electricity and heat, the inability to transfer heat to two working-fluid media, more than 50% decrease in efficiency at high operating temperatures, the inability to use them for multiple purposes, and the inability to have both high efficiency and high temperature parameters simultaneously, leading to more than 40% heat losses in thermosyphon systems, increased costs, and required space. Using the idea of a multi-purpose collector with a heat pipe technique, phase change oscillation, and vacuum insulation with hybrid photovoltaic panels, a micro solar system has been created that can simultaneously produce electricity, heating, and cooling while allowing for multi-purpose use and heat transfer to two working-fluid media. It is possible to operate three solar systems simultaneously with maximum efficiency and minimum cost and required space for all areas, including those without access to city electricity and gas. The heat pipe oscillates between the condenser and evaporator sections and transfers the absorbed solar energy in the evaporator section to the working fluid in the condenser section through a nanofluid phase change process. At the same time, adjustable photovoltaic panels produce the required electrical energy while the lower part of the panel absorbs and transfers heat to the second working fluid through embedded triangular and rectangular channels. This design allows the multi-purpose collector to work as a micro solar system and enables simultaneous operation of three solar systems with maximum efficiency and minimum cost and required space for all.
