What is the effect of storable solar power bank portable outdoor solar panels?

Homeowner, you need to know how to maximize the use of solar panels to generate electricity (my method below is suitable for situations where the weather in the south is cloudy and sunny)

< p>For example The solar panel is about 50w18v2.7a, but the electric energy output from the solar panel will be greatly reduced once the voltage of the solar panel is increased. Therefore, the energy generated by the solar panel generally needs to be charged to the voltage. of the solar panel itself to reach its maximum value Personally, I usually use 50w18v to power laptops (the input parameter is 12-24v2.5a, the input power is more faster than 5v2a power bank and faster than 5v2a6v3a9v2a12v1.5a which requires step-down module), you can maximize the power generated by the solar panel and store it immediately. This method is suitable when the tempps is unstable. Depending on my 50W power generation panel, sometimes the power. generated is 12-18 V, several hundred milliamps up to a maximum of more than 2 A. Even if the efficiency is low, it can be used without being lost by voltage reduction.

If you charge a 5V power bank, the charging effect will be the best on a sunny day, but the voltage reduction module loss on a cloudy day will be the best. Ultimately, charging the power bank is very insignificant and the efficiency is greatly reduced, but it. It's still better than low power that can't be charged. Power output of at least 50w is still more efficient than 10w14w21w28w.

So I suggest you buy a high power portable foldable solar battery board

< p>I already bought a good board from a company. I can recommend it to you if youneed it.

Which is more durable, Tianneng or Chaowei?

Solar energy is divided into photothermal conversion and utilization and direct photoelectric conversion. The moderator should ask questions about the type of direct photoelectric conversion.

Direct light-to-electricity conversion method This method uses the photoelectric effect to directly convert solar radiation energy into electrical energy. The basic device for converting light into electricity is the solar cell. A solar cell is a device that directly converts solar energy into electrical energy through the photovoltaic effect. When the sun shines on the photodiode, the photodiode converts light energy from the sun into electrical energy, producing current. When many batteries are connected in series or parallel, a solar cell array with power output relatively important can be formed. Solar cells are a promising new energy source with three major advantages: solar cells have a long lifespan and can be invested once and used for a long time as long as the sun exists, they are different from production thermal energy; and nuclear energy production. In comparison, solar cells do not cause environmental pollution; Solar cells can be used in both large, medium and small sizes, ranging from a medium-sized power plant with a million kilowatts to a solar battery for one. domestic, which is unmatched by other energy sources.

As for the range of use of batteries, they range from flashlights and watches to vehicle-mounted batteries and even solar power plants. However, there is a limitation: the duration of sunshineement in the area to be used should be long and the intensity of sunshine cannot be too weak. I really like solar flashlights, portable solar chargers and others.

Tianneng batteryand Chaowei battery are both domestic first-class battery brands. Tianneng battery is more durable than Chaowei battery. In fact, battery durability is related to many factors such as usage environment, usage frequency, usage method, etc. Under the same conditions, Tianneng battery performs better.

Chaowei Battery was established in 1998. It includes electric moped batteries, electric road vehicle batteries, electric vehicle batteries, solar and wind energy storage, Lithium batteries and Jinchaowei batteries for electric bicycles.

Tianneng Battery was established in 1986and ranks 30th among new energy companies in the world. It is an industrial group which mainly produces electric moped batteries, lithium batteries, tubular batteries, wind and solar energy storage batteries, and integrates research, development, the production and sale of renewable lead resources, recovery, recycling and other new energy sources.

Relatively speaking, the Tianneng battery brand has a longer history and has accumulated certain experience and technology. Currently, Tianneng battery is the leader in the power battery industry, accounting for more than 60% of the market. Share In terms of product quality, it is more secure online, and it is also more secure in terms of after-sales service.

Detailed information:

Authenticity of Tianneng battery identification:strong>

1. There are special technical standards for plastic housing structure design, plastic housing material, plastic housing color, etc. of each Tianneng battery model.

2. The upper cover of the battery plastic case bears the Tianneng brand and special anti-counterfeiting coding marks “TNG” and “☆”, and will be replaced from time to time;

2. p>3. There will also be an identification mark on the bottom of the molded battery case, matching the relevant information on the molded battery case.

4. For Tianneng original batteries, from August 2018, the battery packaging box and battery screen model identification series "DZM" have all been changed to "DZF".

5. The position of the battery screen, the thickness of the foStandard font format and the complete screen content strictly conform to the technical documents of Tianneng and have specific requirements for the use of copyright.

6. Tianneng genuine batteries, from December 2018, the QR code dot matrix changed from a rectangular dot matrix to a character dot matrix. Currently, the letter “N” is used as a dot matrix. .
