The solar photovoltaic monitoring system is used in hydrological and water conservancy, meteorology, highway monitoring, forestry, mountain tops, scenic fire prevention and anti-theft monitoring, and other monitoring systems, without traditional complicated wiring, and the system is pollution-free, easy to maintain, low cost, long service life. The continuous supply of solar photovoltaic power for 24 hours a day ensures the stable and continuous operation of the monitoring system, reflecting the advantages of unattended, efficient and stable operation of solar photovoltaic power generation.
Solar (photovoltaic) power generation system solves the problem of power supply for residents in remote areas; solves the problem of rural public facilities lighting and electricity consumption; solves the problem of freeway signal and lighting power supply; solves the problem of border posts and island power supply and other grid power supply costs are high There is a wide range of application prospects for users' power consumption.
Solar photovoltaic power generation system is the most reasonable independent power supply system. This rationality is reflected in: 1. Photovoltaic power generation is a static operation, there is no moving parts, and it has a long service life, requiring little or no maintenance. Second, the photovoltaic system is modular and can be installed close to the place where electricity is consumed. In areas far from the grid, transmission and distribution costs can be reduced, and the reliability of the power supply facilities can be increased.
First, solar photovoltaic monitoring system program (30W)
1.1 System Specifications
