Top ten brands of photovoltaic inverters: Huawei, SUNGROW, SINENG, Growatt, GOODWE, TBEA, KELONG, KSTAR, Ginlong, Shouhang New Energy.
1. Huawei Huawei
Huawei's market share increased from 22% to 23%. Not only has its market share been lost due to global suppression. by the United States, instead of decreasing, it has expanded. You can imagine the difficulties involved. I believe that the de-Americanization of materials is essentially complete and the rate of localization has increased significantly. . Huawei has ranked first in the world for six consecutive years.
2. Sungrow SUNGROW
Sungrow's market share increased from 13% to 19%, an increase of 6%, an astonishing increase, and it ranked second in the world for six consecutive years. Judging by the growth rate, it is very likely that it will overtake Huawei in 2021. If you had bought the shares of Sungrow at the beginning of the year, these people would probably laugh in their dreams at night. It's a shame they didn't have the money to buy them at first.

It's good to have ideas, but current technology is far from enough. This is not because Huawei's technology is insufficient, but because no one can do it right now.
Solar charging Cell phones were made in Japan and South Korea a few years ago, but they were all failures and had no merit.practical meaning.
The characteristics of solar energy are that it occupies a large area and has strict requirements for light. The largest surface area of a mobile phone is only about 0.0081 square meters. You should know that human technology is actually very backward. The charging efficiency can only reach 0.17, which requires a 70W solar panel. In this case, the mobile phone needs a solar panel. battery close to one square meter How to use such a large mobile phone if it is powered by a card? Additionally, this type of loading speed is also very slow. Do you need to charge the phone by exposing it to the sun for a long time during the day and use it at night?
Thermal energy is directly converted into electrical energy. Currently, it can only measure temperature, and not produce electricity. Nowadays, thermal power plants areagain thermal energy → mechanical energy → electrical energy. To put it bluntly, they are like steam engines that boil water to run the generator. Can a cell phone hold a steam engine? Can people handle that much heat?
The power consumption of the calculator screen is very low and it has a battery to store energy. Nowadays, the power consumption of mobile phones is even too high. If the conversion efficiency is not taken into account, this small amount of heat cannot satisfy even one percent of a mobile phone's needs.
