Foldable Solar Panels

What is Foldable Solar Panel? How Does Foldable Solar Panel Work?

What is Foldable Solar Panel? Just as the name suggests, this is a solar panel that uses solar cells to convert solar energy into electrical energy, and it can be folded. Solar energy is a non-polluting and inexhaustible source of energy, therefore, in the face of the pollution and shortage of petrochemical energy, how to […]

Top 5 Things You Should Know About Mini Solar Panels

There are a lot of mini solar panels for sale on the market, the price and quality are variable. The 3v, 5v, 6v and 12v mini solar panels are getting more and more popular, especially the demand of 12 volt mini solar panel is increasing very fast, the application of the mini solar panel is also […]

QUICK OVERVIEW

Solar Panels

Also called solar cell module, are assembled by several solar cells. It is the core part of the solar power generation system, and it is also the most important part of the solar power generation system. The solar cell, also known as "solar chip" or "photocell", is a photoelectric semiconductor wafer directly generated by sunlight. Single cell solar cells cannot be used directly for power supply. As a power source, several single solar cells must be connected in series or in parallel, and be sealed tightly to be the cell module.

At present, crystalline silicon (including polycrystalline and monocrystalline silicon) is the most important photovoltaic material, its market share is above 90%, and it is still the main material of solar cell for a long time in the future. The production technology of polycrystalline silicon materials has been controlling in the hands of 10 factories from 7 companies, they all come from three countries, there are the United States, Japan, and Germany, forming the situation of technical blockade and market monopoly. The main demand for polycrystalline silicon comes from semiconductors and solar cells. According to the requirement of purity, it is divided into electronic grade and solar energy grade. Among them, electronic grade polycrystalline silicon accounts for about 55%, and solar cell grade accounts for 45%.

With the rapid development of the photovoltaic industry, the growth of the demand for solar polycrystalline silicon is higher than semiconductor polycrystalline silicon. It is expected that the demand for solar polycrystalline silicon will exceed the electronic grade polycrystalline silicon by 2020. In 1994, the total output of solar cells was only 69MW in the world, and in 2004 it was close to 1200MW, which increased by 17 times in just 10 years. Experts predict that the solar photovoltaic industry will exceed nuclear power in the first half of the twenty-first Century to become one of the most important basic energy sources.

Flexible Solar Panel

It is one of the most innovational technologies of today. This rings true for so many reasons. Once, use solar panels to produce power were just an idea, but now the solar industry has exploded and many new solar products are selling in the market. It brings not only benefits to an individual but also to all human being. This special creative technology makes sustainable and renewable energy in a better way that will not cause any problems with the environment.

Solar Panel Kits

Usually, it includes an array of photovoltaic modules, a controller, a battery pack for storage power, an inverter, connectors, cables and optionally a solar tracking mechanism, that is also called a photovoltaic system. The Photovoltaic System also includes smaller accessories. A series of solar cells are installed in a stationary location (ie: rooftops of homes, base-station locations on the ground etc.) and can be connected to a battery bank to store energy for off-peak usage. They can also be used in addition to mains-supply chargers for energy saving during the daytime. The characteristics of the small solar power supply system are that the system has only DC load and small load power, and the whole system is simple in structure and easy to operate. Its main uses are the general household system, all kinds of civilian DC products and related entertainment equipment. For example, the photovoltaic system has been widely used in the western region of China, and the load is DC lamp, which is used to solve the problem of home lighting in the area without electricity.

Solar Chargers

Use solar energy to supply electricity to the devices or charge batteries. They are generally portable or foldable. It can charge lead acid or Ni-Cd battery banks up to 48 V and hundreds of ampere-hours (up to 4000 Ah) capacity or more. Usually, this type of solar charger setups generally uses an intelligent charge controller for protecting the charging devices.

Most portable or foldable chargers can get the free power from the sun only. But some special solar chargers can work either way (recharged by the sun or plugged into a wall plug to charge up). Examples of solar chargers in popular use include:

  • Small portable or foldable models designed to charge a range of different Smartphones, iPhone, mobile phones, cell phones, iPods or other small USB Devices.
  • The Foldout models designed to sit on the dashboard of an automobile and plug into the cigar or 12v lighter socket to keep the battery topped up while the vehicle is not in use.
  • The solar Flashlights or torches, often combined with a secondary means of charging, such as a kinetic (hand crank generator) charging system.
  • The Public solar chargers permanently installed in public places, such as parks, living zones, squares, and streets, which anyone can use for free.
