The development potential and application of solar lights

With the increasing depletion of traditional energy sources, solar energy has become a very promising new energy source, and solar photovoltaic power generation is the main solar energy utilization mode. Photovoltaic power generation system is divided into: grid system and independent power supply system. The grid system can be seen as a centralized or distributed solar power plant, while the independent power supply system is not connected to the grid and directly provides power to the load. Solar lighting systems belong to the latter.

Solar street lights generally use batteries as energy storage devices. This independent solar lighting system has high practical value, covering areas including remote areas, deserts, border posts, and other areas not covered by the power grid.

At present, research in the field of solar lighting is still limited to the coordination of components and the basic functions of national control, while the research on the MPPT algorithm and battery energy management control of solar lighting systems is not deep enough. In addition, the existing solar lighting system uses energy-saving lamps as the light source, and the illuminance cannot meet the needs of traffic lighting and other occasions. Therefore, based on the solar street lamp lighting system, high-intensity gas discharge lamps have broad application prospects.

1. Energy-saving advantages of solar lights

With the development of my country's society and economy, my country's lighting power consumption will be greatly increased, and green energy-saving lighting is getting more and more attention and application. As a cold light source, solar LED lighting has many advantages-high efficiency, green, safe, reliable, stable quality, long service life, simple installation, etc. It has been widely used in green lighting, road lighting, advertising light box lighting, urban Landscape lighting and home lighting systems, but the high investment cost of solar LED lights has become a bottleneck for development.

At present, lighting consumes about 20% of the entire power consumption, and reducing lighting power consumption is an important way to save energy. In order to achieve this goal, the industry has developed a variety of energy-saving lighting appliances and achieved certain results.

2. Promote the application of solar lighting

As an emerging green energy, solar energy has been rapidly promoted and applied with its unparalleled advantages. As the fourth-generation new light source, it is used in urban lighting and beautification, road lighting, courtyard lighting and indoor lighting. Especially in remote areas without electricity, solar lighting has broader application prospects.

Most people think that energy-saving lamps can save 4/5 of electricity is a great innovation, but LED lights and solar lights can save 1/4 of energy. In addition, LEDs also have the advantages of high light quality, basically no radiation, reliability and durability, and extremely low maintenance costs.
