Wind-solar hybrid LED street lights not only save energy, but their rotating fans create a beautiful sight. Saving energy and beautifying the environment is truly two birds with one stone. Each wind-solar hybrid LED street light is a standalone system, eliminating the need for auxiliary cables, making installation easy. Today, street lamp corporation Tianxiang will discuss how to manage and maintain it.
Wind Turbine Maintenance
1. Inspect the wind turbine blades. Focus on checking for deformation, corrosion, damage, or cracks. Blade deformation can lead to uneven swept area, while corrosion and defects can cause uneven weight distribution across the blades, leading to uneven rotation or wobble during wind turbine rotation. If cracks are present in the blades, determine whether they are caused by material stress or other factors. Regardless of the cause, blades with U-shaped cracks should be replaced.
2. Inspect the fasteners, fixing screws, and rotor rotation of the wind-solar hybrid solar street light. Check all joints for loose joints or fixing screws, as well as for rust. If any problems are found, tighten or replace them immediately. Manually rotate the rotor blades to check for smooth rotation. If they are stiff or make unusual noises, this is a problem.
3. Measure the electrical connections between the wind turbine casing, the pole, and the ground. A smooth electrical connection effectively protects the wind turbine system from lightning strikes.
4. When the wind turbine is rotating in a light breeze or when manually rotated by the streetlight manufacturer, measure the output voltage to see if it is normal. It is normal for the output voltage to be approximately 1V higher than the battery voltage. If the wind turbine output voltage is lower than the battery voltage during rapid rotation, this indicates a problem with the wind turbine output.
Inspecting and Maintaining Solar Cell Panels
1. Inspect the surface of the solar cell modules in wind-solar hybrid LED streetlights for dust or dirt. If so, wipe with clean water, a soft cloth, or a sponge. For difficult-to-remove dirt, use a mild detergent without an abrasive.
2. Inspect the surface of the solar cell modules or ultra-clear glass for cracks and loose electrodes. If this phenomenon is observed, use a multimeter to test the open-circuit voltage and short-circuit current of the battery module to see if they are consistent with the battery module’s specifications.
3. If the voltage input to the controller can be measured on a sunny day, and the positioning result is consistent with the wind turbine output, the battery module output is normal. Otherwise, it is abnormal and requires repair.
FAQ
1. Safety Concerns
There are concerns that the wind turbines and solar panels of wind-solar hybrid street lights may be blown onto the road, injuring vehicles and pedestrians.
In fact, the wind-exposed area of the wind turbines and solar panels of wind-solar hybrid streetlights is much smaller than that of road signs and light pole billboards. Moreover, the street lights are designed to withstand a force 12 typhoon, so safety issues are not a concern.
2. Lighting Hours Unguaranteed
There are concerns that the lighting hours of wind-solar hybrid streetlights may be affected by weather, and the lighting hours are not guaranteed. Wind and solar energy are the most common natural energy sources. Sunny days bring abundant sunlight, while rainy days bring strong winds. Summer brings high sunlight intensity, while winter brings strong winds. Furthermore, wind-solar hybrid streetlight systems are equipped with sufficient energy storage systems to ensure sufficient power for the streetlights.
3. High Cost
It is generally believed that wind-solar hybrid streetlights are expensive. In reality, with technological advancements, the widespread use of energy-saving lighting products, and the increasing technical sophistication and price reductions of wind turbines and solar energy products, the cost of wind-solar hybrid streetlights has approached the average cost of conventional streetlights. However, since wind-solar hybrid streetlights do not consume electricity, their operating costs are far lower than those of conventional streetlights.
