The design of solar street lights has the same basic principles as general solar lighting, but requires more consideration. Taking photosynthetic solar LED high-power street lights as an example, we will analyze them in several aspects.
Selection of solar cell modules
Design requirements: In the Sanmenxia area, the load input voltage is 24V, the power consumption is 34.5W, and the daily working hours are 8.5h, ensuring a continuous rainy and rainy day of 7 days.
The annual average radiation amount in the Sanmenxia area in the past two decades is 107.7 Kcal/cm2, and after simple calculation, the peak sunshine hours in the Changsha area are about 3.424 hours;
⑵ Daily power consumption of load==12.2AH
⑶ The total charging current required for Changsha Photosynthetic Solar Module=1.05 × twelve point two × (20+7) ÷ 20 ÷ (3.424 × 0.85)=5.9A
The minimum total power of photosynthetic solar modules=17.2 × 5.9=102W
Choosing a standard battery module with a peak output power of 110Wp and a single 55Wp should ensure the normal operation of the street light system in most cases of the year.
