The first method: use a DC clamp meter to test the current and voltage of the light source, and multiply the two to calculate the power.
Regardless of the size of solar lamps, a charge and discharge control circuit with good performance is essential.
Under the condition of light, the solar street light converts the solar energy into electrical energy through the solar panel and stores it in the battery.
You can see various types of solar controllers in the market.
Solar cells are semiconductor devices that directly convert solar radiation into electrical energy based on the photovoltaic effect of semiconductors.
The development of science and technology has brought about the continuous improvement and improvement of people's lives. As a new type of product, LED street lights provide the convenience of lighting for people's travel.
