[China Aluminum Network] Aluminum will produce ash after smelting, which is an inevitable result of smelting and inevitable. The aluminum ash is composed of alumina, aluminum nitride, other oxides, chlorides and aluminum. If this kind of product is not handled well, it will affect many problems. First, the economic benefits of the recycled aluminum industry The amount of aluminum contained in the aluminum ash removed from the furnace is 45% to 75%, because the amount of aluminum ash is about 15% of the amount of melting in the furnace. Therefore, how to increase the amount of aluminum recovered from the aluminum ash is regenerated. Aluminum industry is an important issue. In other words, if the ash processing is not good, it will directly affect the economic benefits of the recycled aluminum industry. Second, the impact on the cost of recycled aluminum products If a factory with a monthly smelting capacity of 3,000 tons is used as an example, the output of aluminum ash slag can reach 450 tons, and the aluminum content can reach 202.5 to 337.5 tons. The recovery rate of aluminum is 45%, and the recovery of aluminum is 90~152t. If the recovery rate is 70%, the recycled aluminum can reach 142~236t, with a difference of 52~84t. This difference is equivalent to gross margin of 2%~3%. However, the recovery of aluminum from aluminum ash dross has a higher recovery rate, ie 70% recovery, and the remaining residue is difficult to handle. Aluminum ash containing more than 30% aluminum can be used as a deoxidizer for steelmaking. . Therefore, most recycled aluminum companies now avoid excessive recycling of aluminum ash. Instead, they sell aluminum slag to aluminum slag treatment plants or steelmaking deoxidizer plants. Therefore, the recovery rate of aluminum ash residues has a direct impact on the cost of recycled aluminum products.
In a well-balanced grid-connected configuration, a solar array generates power during the day that is then used in the home at night. Net metering programs allow solar generator owners to get paid if their system produces more power than what is needed in the home. In off-grid solar applications, a battery bank, charge controller, and in most cases, an inverter are necessary components. The solar array sends direct current (DC) electricity through the charge controller to the battery bank. The power is then drawn from the battery bank to the inverter, which converts the DC current into alternating current (AC) that can be used for non-DC appliances. Assisted by an inverter, solar panel arrays can be sized to meet the most demanding electrical load requirements. The AC current can be used to power loads in homes or commercial buildings, recreational vehicles and boats, remote cabins, cottages, or homes, remote traffic controls, telecommunications equipment, oil and gas flow monitoring, RTU, SCADA, and much more.

What Is A Solar Panel?
Solar energy begins with the sun. Solar panels (also known as "PV panels") are used to convert light from the sun, which is composed of particles of energy called "photons", into electricity that can be used to power electrical loads.
Solar panels can be used for a wide variety of applications including remote power systems for cabins, telecommunications equipment, remote sensing, and of course for the production of electricity by residential and commercial solar electric systems.
How Do Solar Panels Work?
Solar panels collect clean renewable energy in the form of sunlight and convert that light into electricity which can then be used to provide power for electrical loads. Solar panels are comprised of several individual solar cells which are themselves composed of layers of silicon, phosphorous (which provides the negative charge), and boron (which provides the positive charge). Solar panels absorb the photons and in doing so initiate an electric current. The resulting energy generated from photons striking the surface of the solar panel allows electrons to be knocked out of their atomic orbits and released into the electric field generated by the solar cells which then pull these free electrons into a directional current. This entire process is known as the Photovoltaic Effect. An average home has more than enough roof area for the necessary number of solar panels to produce enough solar electricrity to supply all of its power needs excess electricity generated goes onto the main power grid, paying off in electricity use at night.
