In July 2021, Another Chinese PV panel manufacturing company announced that it had developed a high-efficiency solar panel module with a maximum conversion efficiency of 23.53%, beating the module efficiency record of 23.01% set in January 2021. The high-efficiency module has been independently tested and verified by TUV Rheinland Laboratories, a leading global testing institute. The module uses the latest TOPCon cell technology and new packaging technology.


At the SNEC exhibition held in June this year, the latest high-efficiency modules from major companies were unveiled. TOPCon and HJT cell technologies are the core of high-efficiency modules, but of course there are also companies that have created high-efficiency modules by combining the strengths of both technologies at a controlled cost, but the final module efficiency did not exceed 23%.


Although the maximum conversion efficiency of solar panel modules exceeds 23.5%, their mass production efficiency is not expected to be too far off. With the continuous progress of solar technology and R&D support, it is likely that the efficiency will be increased by another notch during the year, bringing PV module efficiency to a new level. At the same time, it can also help other related businesses such as solar street lighting to achieve better development.


Solar street light is a kind of street light using solar energy as an energy source, because it is not affected by the power supply, without trenching and burying lines, do not consume conventional electricity, as long as the sun is sufficient to install in situ, etc., so it is widely concerned by people, and because it does not pollute the environment, and is known as a green product. Solar street lights can be used for street, road, lawn lighting, and can be used for population distribution density is small, traffic inconvenience economic underdevelopment, the lack of conventional fuel, it is difficult to use conventional energy generation, but the solar energy resources are abundant in the region, in order to solve the problem of household lighting of people in these areas.
