In today’s outdoor lighting, the street lights on both sides of the road, the landscape lights in parks and squares, courtyard lights, and those warning signs have joined the solar energy design, which can meet the power demand without municipal power. While reducing the installation cost, it also greatly saves energy and reduces the pressure of municipal power.
Solar panels are particularly important in these new lighting designs. However, it should be noted that solar panels are made of polycrystalline silicon, monocrystalline silicon, and other crystal structure materials, which are prone to hidden cracks.
