Smart Solar Charger

We took solar power from stationary to portable, from rooftops to backpacks. Powering your phone, headlamp, camera or whatever essential gear is in your kit from the sun is a reality. It’s a little surreal, opening a solar panel, plugging in a phone, and watching as it starts to charge.

From truck beds to backpacks, our foldable solar chargers can be hung, strapped, and packed for ultimate portability. With LED indicators that display strength of solar conditions and give feedback on the speed of charging, it's never been easier to harness the power of the sun wherever you go.

The sun produces a lot of energy every year, which we call solar energy. The sun radiates 20,000 times the energy in Australia every day than the energy we get from oil, natural gas and coal, and, for us, solar energy is inexhaustible for the remaining five million years of the sun’s lifespan. Inexhaustible. Solar panels are composed of solar cells, which can convert solar energy in sunlight into electrical energy. Because solar cells can generate electricity directly from sunlight, they are the most reliable of all our current power generation technologies. This is why solar cells are widely used in space and in remote areas where problems are difficult to solve.

How do solar cells work?

Solar cells are composed of silicon atoms. You can think of atoms as bricks on buildings—just like building blocks in Lego, but because of their small size, you need special tools to see them. The solar cell comes from a layer of silicon wafers. The size of the silicon wafer layer is similar to that of a dinner plate, but it is much thinner-only about three times thicker than a normal hair.

Turning the silicon crystal layer into a solar panel requires a special preparation process. The silicon crystal layer needs to be heated to 1000 degrees Celsius, and then a layer of metal sheet is placed on the back of the layer, while covering the solar cell with a layer with holes Metal mesh and let this side rush toward the sun.

When the preparation of 60 solar cells is completed, they will be fixed on a layer of glass to make solar panels. Generally speaking, the solar power supply system on the roof has 10-50 solar panels, while millions of solar panels are installed in the rural solar power plants.

Every silicon atom contains electrons of extremely small size and light mass, and these electrons carry a weak charge. When sunlight falls on the solar panel, it will hit one of the electrons and move it out of the electron orbit. These hit electrons can move freely, but the special structure of the battery allows the electrons to only move in a direction toward the sun.

Therefore, when sunlight falls on the solar cell, many electrons will deviate from their orbits and become free electrons. Because of the characteristics of the solar cell, the electrons can only move upwards, thereby generating current that can drive household appliances.

If the sunlight falling on the solar cell is stronger, more electrons will be impacted out of its orbit and the current generated will be greater. If the weather is not clear, the number of electrons hit will be reduced, and the current generated will be reduced by 75% or more. At night, solar panels do not produce any electricity, and the power supply at this time depends entirely on batteries or other sources of electricity.

How should we use solar cells?

Solar cells are the cheapest way to generate electricity-even cheaper than a new thermal power plant or nuclear power plant. This is why the global solar cell installation rate is 5 times that of coal power and 20 times that of nuclear power.

In Australia, basically all newly built power plants are solar power plants or wind power plants. Electric cars that use solar and wind power to generate electricity can replace gasoline cars that produce pollution. Solar and wind power generation can also be used for heating and cooling of houses, replacing traditional coal and natural gas heating methods.

The use of solar and wind energy can help reduce greenhouse gas emissions that cause damage to the earth. Compared with other energy sources, the cost of solar and wind energy is very low and will become lower; if we use more wind or solar energy, we can Accelerate the reduction in the use of traditional energy sources (such as coal, oil and natural gas) that harm the planet.

In addition, silicon atoms are the world's second-largest atoms in reserves (the first is oxygen atoms). In fact, most sand and stones are made of silicon and oxygen, so we cannot use up all the silicon for solar cells.
