Detailed information :

Composition of the solar panel and functions of each part:

1. Tempered glass: Its function is to protect the main body of power generation (such as battery cells), and there are requirements for its transmission selection of light:

1. Light transmittance should be high (usually above 91%);

2. Ultra-white tempered treatment.

2. EVA: usefulsed to bond and fix the tempered glass and the main body of the power generation (battery sheet). The quality of the transparent EVA material directly affects the lifespan of the exposed EVA component. the air is prone to aging and yellowing. This affects the light transmission of the module and therefore the power generation quality of the module.

In addition to the quality of the EVA itself, the lamination process of component manufacturers also has a big impact, for example, if the bonding degree of the EVA is not conforms to standards and whether the bonding strength between EVA is quenched. The glass and backplane are insufficient, this will cause premature aging of the EVA and affect the life of the components.

3. Cells: The main function is to produce electricity. The main market for power generation is crystalline silicon solar cells and carbon dioxide solar cells.thin uches, both of which have their own advantages and disadvantages.

Crystalline silicon solar cells have relatively low equipment costs, but high consumption and cell costs. However, the photoelectric conversion efficiency is also high, and they are more suitable for generating electricity under outdoor sunlight.

Thin film solar cells have relatively high equipment costs, but the consumption and battery costs are very low, but the photoelectric conversion efficiency is more than half of that of cells made of crystalline silicon, but the low light effect is very good, under ordinary light. Can also produce electricity, like solar cells in a calculator.

4. Backplate: Function: sealing, insulation and waterproofing. Generally, TPT, TPE and other materials are used and mustnt be resistant to aging. Most component manufacturers offer a 25-year warranty. Tempered glass and aluminum alloy generally pose no problem. .

5. Aluminum alloy: protects rolled parts and plays a certain sealing and supporting role.

6. Junction Box: Protects the entire power generation system and acts as a power transfer station. If the component is short-circuited, the junction box will automatically disconnect the short-circuited battery string to prevent short circuiting. The most critical thing to avoid burnout of the entire system junction box is the diode selection. Depending on the cell type of the module, the corresponding diodes are also different.

7. Silica gel: sealing function, used to seal the junction between components and aluminum alloy frames, components and junction boxes. SomeCompanies generally use double-sided tape and foam to replace silica gel. used in China and the process is simple, convenient, easy to use and inexpensive.

Can the GPRS of the lock still work normally without the solar panel in the Hello Bike basket?

< strong>Removed with a #5 screwdriver

The bottom panel of the shared bike basket is actually a piece of solar panel, which provides power to the GPS system and the automatic bicycle lock. Once marketers block solar panels in small advertisements, shared bikes will lose power over time and become inefficient, and could become "zombie bikes" that take over the streets.

Recently, the urban management of Jiang'an District organized three shared bicycle operating companies to batch clean the "psoriasis” on solar panels.

This is also the first time that Wuhan's urban leadership has focused on eliminating "psoriasis" on shared bicycles. A battle to wipe out the bike-sharing “psoriasis” that is about to spread across the city has quietly begun.

Can the shared bike charging base be used to charge mobile phones?

Yes.

There is a black solar panel in the bicycle basket, which is convenient for charging the car lock and has nothing to do with GPRS. There is now a transparent plastic plate attached with screws on top of the solar panel, and the top of the plate is covered with dense ridges.

The shared bike chargercannot be used to charge mobile phones. This type of solar charger cannot produce sufficient voltage and currentthat under strong sunlight, especially in winter, or when the sunlight is insufficient or the solar cell area is too small, it cannot provide sufficient voltage and current. are low, so it is difficult to charge if the device being charged, such as a mobile phone, is turned on, not only will it not be able to charge, but it will be consumed and the voltage will become lower and lower. .

Instructions for shared bike solar panels

The voltage of shared bike solar panels is about 5V. Thin film solar panels developed by Hanergy are used. It is more flexible than crystalline silicon solar cells and has the characteristics of being foldable and lightweight. Solar charging can help shared bikes solve the power demand problem of smart locks. The smart lock of shared bicycles has functionss such as satellite positioning and mobile communication, so it still has a certain energy demand.
