At present, the traffic lighting tools on the market include the following: traditional electric lighting facilities, new energy-saving lighting facilities, reflective lighting facilities, etc. Among them, new energy-saving lighting facilities include solar road studs, solar street lamps, wind street lamps, and complementary street lamps combining light and wind energy. The lighting effect of solar road stud lies in its solar panel with high conversion efficiency. It can be said that the most important component of solar road studs is the solar panel.
However, a solar road stud is a safety device installed on the road, which has to withstand many times of rolling and impact of vehicles every day. Therefore, an excellent solar road stud must have reliable solar panels. This requires that solar panels not only achieve high conversion efficiency, but also have strong impact resistance. Next, let's compare several common solar panels on the market.
The first solar road stud used traditional solar panels. As you can see, the solar panel of this solar road stud is a monocrystalline silicon product. The front of the solar panel is welded with metal wires. The mechanical properties of this solar road stud product are the most fragile. This solar panel will break as long as it is slightly bent.
Let's take a look at another solar panel used by the solar road stud. This solar road stud uses no solar panels in front of it. There is any wire welding. However, the copper substrate is designed behind the solar panel products, which can well protect the solar panels. This solar panel makes the charging efficiency of solar road stud higher, and its strength and toughness are greater. The solar panel cannot be damaged by slight bending. However, if you break it hard, the solar panel will still be damaged. Therefore, the road studs using this solar panel can be used in places with small traffic flow, such as road edges, gardens, squares, etc.
Let's take another look at the solar panel of NOKIN solar road stud. Each charging unit is completely independent, with an aluminum substrate behind it. The solar panel of NOKIN solar road stud is a kind of solar panel with greater strength and flexibility. This solar panel can even be folded in half without damage. Therefore, this kind of solar panel is the most suitable for solar road stud products. NOKIN solar road stud adopt imported solar panels, which can be used in busy traffic areas. NOKIN solar road stud have a service life of more than 3 years.
