Design requirements: in Guangzhou, the load input voltage: 24V-power 34.5W, 8.5H of hours of work per day to ensure continuous rainy days 7 days.
⑴ in Guangzhou for nearly 20 years the average annual radiation 107.7Kcal/cm2, by simple calculation peak sunshine hours is about 3.424H in Guangzhou;
⑵ load power consumption =12.2AH
⑶ Solar components required the total charge current =1.05x12.2x (3.424x0.85) =5.9A
Here, design a minimum number of days between two
