Portable Solar Charger The Most Extensive

Living in the modern city of our daily life are not open electricity, Portable Solar Charger but you have imagined in some remote areas, people at night the basic lighting power supply can not guarantee it?

In order to solve the problem of power supply in remote areas, scientists around the world have been working to study the use of new energy.

In the new energy, the use of solar energy is the most extensive. General solar equipment usually requires several well-trained workers, spend a few days to assemble. Portable Solar Charger But today to introduce this by the solopower company designed portable solar energy equipment, in a few minutes a person to complete the assembly, without any equipment and tools of the auxiliary.

The kit includes a flexible and durable solar panel, battery, connector, lighting and charger, all the size of the parts just can be loaded into a plastic bucket, Portable Solar Charger the weight does not exceed 20 pounds.

Solar energy is an attractive energy source for portable devices. Portable Solar Charger For some time it has been widely used for applications such as calculators and space shuttles. Recently, people are considering the use of solar energy, including mobile phone chargers such as a wider range of consumer electronics applications.

However, the power provided by solar panels is highly dependent on the working environment. This includes factors such as optical density, time and location. Thus, the battery is typically used as an energy storage unit. When the energy from the solar panels, you can charge the battery; when the solar panels to provide less power, the battery can power the system. How do we design a lithium example battery charger to get the most power from a solar cell and effectively charge the lithium battery? First, we will discuss the working principle of solar cells and electrical output characteristics; then, we will discuss the battery charging system requirements and matching solar cell characteristics of the system solutions in order to obtain the maximum power from the solar cells.

The current source IPH produces a current proportional to the amount of light falling on the solar cell. In the absence of a load connection, Portable Solar Charger almost all of the current flows through the diode D, and its forward voltage determines the open circuit voltage (VOC) of the solar cell. The change in voltage is strictly dependent on each type of solar cell. However, for most silicon cells, the voltage range between 0.5V and 0.8V is exactly the forward voltage of the p-n junction diode.

The parallel resistance (RP) represents the tiny leakage current present in the actual solar cell, and Rs represents the connection loss. As the load current increases, Portable Solar Charger most of the current generated by the solar cell is diverted to the diode and into the load. For most of the load current value, this only has a very small effect on the output voltage.
