Solar underground lights do not need to lay underground cables, and do not need to pay for lighting electricity. The key components used in solar underground lights, solar panels, solar DC street light intelligent controllers, maintenance-free batteries, and LED lamp beads have all passed the National Development and Reform Commission/GEF/World Bank photovoltaic product certification.

Taiwan's top five inverter factories in the first half of the year

On July 30th, the 22nd International Solar Photochemical Conversion and Storage Conference (IPS-22), jointly sponsored by the Hefei Institute of Material Science and the Chinese Academy of Sciences and sponsored by Sunshine Power, was held in Hefei, attracting American and German. Nearly a thousand experts and scholars from more than 50 countries and regions in the UK, Japan, Korea and China came to the conference.

Recently, Australia will try to use solar and wind energy to produce hydrogen through electrolysis, and then use hydrogen for long-term energy storage in Sydney's natural gas energy.

The light energy conversion efficiency of solar garden lights is affected by a variety of factors, which can be mainly understood from the following aspects: 1, The intensity of sunlight exposure is an important factor. Generally speaking, when the sunlight is more intense, the solar panel is able to convert more energy, thus improving the light energy conversion efficiency. 2, The materials used in solar panels also have an impact on their performance. For example, monocrystalline silicon cells typically have a higher photovoltaic conversion efficiency than amorphous silicon cells. 3, Temperature is a factor that cannot be ignored. Too high or too low a temperature may lead to a decrease in the photovoltaic conversion efficiency of solar panels. 4, We also need to pay attention to the resistance between the cell and the wiring.
