Aliexpress is a marketplace representing a wide range of a wide variety of goods on its territory. Entering the name of the goods in the search field, you can see all the shops that are located on more than 20 pages in each category. Goods can be delivered to any city in the world, where there are delivery services. Consider how to choose solar batteries to aliexpress than they differ among themselves, for which they apply and to which seller it is better to contact.

How do solar batteries work with aliexpress?

In solar panels, predominantly silicon is used, which absorbs the rays of the sun and generates energy from them. There are other substances capable of producing energy more efficiently, but their cost is much more expensive and therefore they are not so often used.

The principle of operation of solar batteries with Aliexpress Based on photoeffect - the ability to absorb the light of the Sun and convert it into an electric current. Silicon belongs to semiconductors. Silicon electrons, absorbing the energy of the Sun, receive an additional impulse and go out of their orbits. The design consists of semiconductors of 2 types: one with disadvantage of electrodes, the other - with an excess, which is divided by its electrodes. The distance between two semiconductors is installed so that the electrodes can overcome it. Thus, the effect of a constant motion of a photocurrent is achieved, which is removed from the plates using thin conductor and loads sold to them. These designs are used for different purposes, ranging from built-in batteries to calculators and household clock, ending with the supply of electricity whole areas.

Varieties of solar panels with aliexpress

Types of solar panels with aliexpress depend on the material from which are made. Manufacturers produce monocrystalline, polycrystalline and flexible photobatabases. The most common component is silicon or its compound. Also differ in the batteries with their capacity and the area associated with it and the use area.

Elements solar batteries And their purpose:

• Aluminum frame that protects elements from damage and provides rigidity to the product.
• Tempered glass with anti-glare properties - protects cells from weather changes and contributes to the absorption of sunlight.
• Two laminating films, upper and lower - provide a dense fit of the components of the protective glass, preventing unwanted refraction of rays.
• Photoisechairs.
• Rear wall of protective film.
• Safety diodes in the connecting box required to prevent overheating of shaded cell fragments.

The main elements besides the cells themselves, do not differ much from different manufacturers. You need to pay attention to the quality of the film. Classa products almost do not lose their transparency and are able to serve for 25 years with loss of quality only in 5%.

Monocrystalline solar panels for Aliexpress

Monocrystalline solar panels on Aliexpress It is easy to distinguish by their appearance: cells have a square shape with beveled corners, the color is bright blue or dark blue, the material structure is homogeneous. Such photocells are produced by using homogeneous silicon, with a mass fraction of 99.9%, which has a cylindrical shape during cultivation, and then cut into thin square plates. Due to the uniformity of the structure, the absorption of light and the transmission of electrical pulses occurs as efficiently as possible. At the efficiency of mono-elements, it does not even affect the fact that the cell area is not fully filled.

Suitable for use in winter frosty time, not much dependent on temperature drops, all year round can be used. For 25 years, cells are aging and lose their capacity by 20%.

Polycrystalline solar panels for Aliexpress

Polycrystalline plates are made simplified by silicon less purity than monochda, therefore, they have an inhomogeneous structure, dark color and less cost compared to single crystals. Consist of heterogeneous crystals and some fractions of impurities. Polycrystals have a shape square or rectangular, without beveled corners. The plates occupy the entire space allotted by them, due to which the light absorption area increases compared with single-crystal plates. But the efficiency still remains lower than in monochiefs. In order to compose performance, you must order a battery on Aliexpress larger than a battery from mono-elements. It will not be too expensive, because solar polycrystalline batteries are 10% cheaper than monocrystalline.

Compared to single-crystal batteries are not suitable for use in frost, but it is better to capture the scattered light, so effective during cloudiness and cloudy weather. For 25 years, cells are aging and lose their productivity by 30%.

Flexible solar panels for Aliexpress

Flexible photobatabases are created using thin film technology. They are made from amorphous silicon or other, more productive materials that are applied to the substrate a very thin layer. Therefore, elastic and easily mounted on uneven surfaces without damaging the structure, if necessary, sewn into portable chargers covers. The size of such batteries exceeds the size of the batteries from mono-elements and polyellements by 2 times. The cost is significantly lower than crystalline batteries.

The popularity of flexible batteries is due to their good ability to absorb the dissipated light, due to which the efficiency of the systems with a power of more than 10 W may exceed 10-15% of the efficiency of models from crystals.

Solar Power with Aliexpress

When buying solar panels, you need to pay attention to their power. Selected depending on the purpose for which battery will be used. Everyone buys, based on their needs. Someone does not want to depend on electricity drops, someone wants to save accounts - pay 1 time and enjoy more than 20 years. There are also situations where there is no access to the common power grid, for example, in remote corners of the country or during trips.

We describe the approximate calculation of the power of solar panels with Aliexpress. Suppose you need to constantly recharge the laptop, modem, camcorder, then you need a product with a power of 40 W. If you plan to connect a refrigerator to the battery, TV, lighting, then you need a battery to 200 W or 2 to 100 W. If you want to recharge only the phone, it will be enough and 5 watts.
