New rural solar Street Lamp design ideas, solar cell module selection
Design requirements: Beijing area, load input voltage 24V power consumption 34.5W, daily working hours 8.5h, to ensure continuous rainy days for 7 days.
⑴ The average annual radiation in Beijing area is 107.7Kcal / cm2 in the past two decades. After a simple calculation, the peak sunshine hours in Beijing area is about 3.424h;
⑵ Daily power consumption of load = 12.2AH
⑶ The total charging current of the Solar Module required = 1.05 × 12.2 × (20 + 7) ÷ 20 ÷ (3.424 × 0.85) = 5.9A
Here, the shortest number of days between two consecutive rainy days is 20 days, 1.05 is the comprehensive loss factor of the solar cell module system, and 0.85 is the battery charging efficiency.
⑷ The minimum total power of solar modules = 17.2 × 5.9 = 102W

The use of standard battery components 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.
