Changhui Lighting: Practical Analysis of Solar Street Lights

Solar street lights use sunlight as energy, do not need to lay complicated pipelines, and are safe, energy-saving and pollution-free. The solar energy control system based on single chip integrates solar photovoltaic technology and single chip intelligent control technology well. Moreover, it has the advantages of simple circuit structure, stable and reliable operation, and strong practicability. 1. Energy saving and environmental protection: According to statistics, changing all street lights to solar street lights can save the power generation of a Three Gorges Hydropower Station. Not only that, solar energy is a clean and renewable energy that not only saves electricity, but also reduces carbon dioxide emissions. Relevant data show that solar street lights can reduce 77.4 million tons of carbon dioxide every year, which is equivalent to saving 31 billion US dollars in carbon dioxide reduction costs! 2. Reliable and durable: solar street lights rarely fail in photovoltaic power generation systems under harsh environmental and climatic conditions; at present, the production technology of most solar cell modules is sufficient to ensure that the performance does not decline for more than 10 years, and solar cell modules can generate electricity for 25 years or longer. 3. Building blocks of installation components: flexible and convenient installation, which is convenient for users to choose and adjust the capacity of solar street lights according to their own needs. 4. Safety: Solar street lights do not use flammable fuels, and do not operate on the network like AC power, resulting in frequent high-voltage surges in situations such as lightning strikes, posing a threat to equipment safety. As long as the design and installation are appropriate, the system has a high safety. 5. Autonomous power supply: Off-grid solar street lights have the autonomy and flexibility of power supply.
