Roof Solar Photovoltaic Power System Solution

With the development of human society, people's demand for electricity is becoming more and more extensive. However, it is difficult and costly to use grid power for residents living in remote areas and certain specific areas. As a result, there are still nearly 10 million inhabitants in China. Failed to use electricity. Today, building a conservation-minded society and advocating a harmonious society in China, solving the problem of power supply to residents in remote areas is an urgent task. Utilizing a wide range of natural energy sources, wind-solar hybrid power supply system for wind energy and solar energy is the most reasonable independent power supply. It not only costs far less than the grid long-distance small-load power supply, but also saves conventional energy and reduces pollution.

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.

Huayu brand solar (photovoltaic) power generation system is the most reasonable independent power system. This rationality is reflected in: 1. Photovoltaic power generation is a static operation, there are 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.

At present, the biggest obstacle to the promotion of new energy products is people's lack of understanding of new energy knowledge. People in many fields that use solar power supply systems are more reasonable than conventional power supply systems do not realize. Now, our government has promoted the circular economy model and constructed A conservation-oriented society has created opportunities for the promotion of new energy products, which will show broad prospects for the promotion and application of solar power station systems.
