For example, the 30W solar street light needs about 60 to 90W solar panels. Then how to choose suitable solar panels for solar street lights? Here are the detail introduction:

1. First of all, you need to know where you are installed, and then you need to know the peak value of your area. Second, you need to know that you can illuminate for several hours every day, and the lamps can be continuously illuminated in several rainy days. Then you can measure the solar panel.

2. The solar street lamp system is composed of a solar cell module, LED lamp head, control box (with controller and battery inside) and lamp pole. Solar battery is also called "solar chip" and "photocell". It is a kind of photoelectric semiconductor sheet that uses sunlight to generate electricity directly. Single solar cells can not be used as a power supply directly. As a solar power source, several single solar battery must be connected in series and tightly sealed into components.
