太阳能路灯（Solar street lamp） Overview of solar street lighting system As the earths resources become increasingly scarce, the cost of basic energy investment is rising, and all kinds of security and pollution Hidden dangers are everywhere. Solar energy as a kind of inexhaustible, inexhaustible safety and environmental protection Energy is getting more and more attention, and is widely used in lighting, because solar street lamps have the following An advantage. ? Solar street lamp lighting installation is simple: no complicated lines are laid. Just make a concrete base. Then fix with stainless steel screws. ? Solar lighting lamps and lanterns need not electricity: it is a one-time investment, no running cost, long-term benefit. ? There is no safety hazard to solar lighting: it is a low-voltage product which is safe and reliable. ? The solar lamp illuminates energy-saving, the green environment, the installation is simple, the automatic control is not maintained and so on The characteristics of the municipal project directly bring obvious advantages. In many new energy technologies, photovoltaic power generation has obvious technical advantages, which is very suitable for remote absence Electricity use. Research and analysis show that even if the cost of photovoltaic power generation is very high, only transmission The ratio of power to transmission distance is less than 100 kw/km, and the photovoltaic power station will extend the power supply to the regular grid The economy. In China, there is no electricity area, the population is small, the residence is scattered, the geographical location is remote, far away from the regular power grid. As a result, Photovoltaic power generation is an ideal way to solve the problem of power supply in these areas and special areas. 5.2.1 overview of solar photovoltaic lighting technology Solar pv technology is a technology that USES battery components to convert solar energy directly into electricity. Solar photovoltaic system The ma
