In fact, solar street lights require professional cables. Many non-professional manufacturers do not consider them because they think that these are not very important. They believe that the resistance of the wires of solar street lights is the same as that of urban street lights. . Actually they are all wrong, we can see their differences from the following comparison:
Line loss: (P)=I2R
LED solar street light: LED light : 100W /12V=8.334A, P=8.3342R≈70R,
Town circuit lamp: high pressure sodium lamp power: 100W/220V=0.445A, P=0.4452R= 0.203R
It is also a 100W lamp, because the working system of solar street lights is low voltage and high current. Suppose the resistance of the street circuit lighting cable is 1 ohm, then the line loss P of the city light circuit is 0.203 W. If the street circuit lighting cable is directly used sOn the solar street light, the line loss is 70W. which is lower than that of the light source. The power is about the same. Therefore, solar street lights must use special cables with very low line losses, and the cables cannot be used casually.
Our family also makes solar street lights. We use professional cables, anti-UV pure copper silicone cables and high-strength anti-aging silver-plated waterproof connectors, which have the smallest resistance and lowest line. loss, fully guaranteeing the complete set. The circuit of the solar street light system is stable.
I hope the answer is useful to you.
