Streetlights serve as a public convenience but also consume a lot of electricity. Nowadays, with energy scarcity, the solution provided by solar and wind hybrid streetlights addresses this issue; however, the principles of wind-solar complementary streetlights are not widely known.
Wind-solar complementary streetlights
are composed of solar panel modules, wind turbines, high-power LEDs, LPS lamps, photovoltaic control systems, wind turbine control systems, and specialized maintenance-free batteries, along with additional components such as mounting brackets for solar panels, turbine accessories, lamp poles, embedded parts, and battery underground boxes.
Wind-solar power generation systems
are devices that convert wind and solar energy into electrical power. The working principle of wind-solar complementary streetlights is as follows: natural wind is used as a power source, where the wind turbine harnesses wind energy, driving the wind generator to convert wind energy into electricity. This electricity is rectified and stabilized by a controller, which converts AC to DC, charging the battery bank for energy storage. The photovoltaic effect directly converts solar energy into DC power for immediate load use or for storage in the batteries as backup.
In fact, the principles of wind-solar complementary streetlights have already been widely adopted abroad, and understanding these principles is essential for better promotion of this technology domestically.
