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.
â‘´ 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.
Solar road lamp factory in Yangzhou main production and sales: Solar Street Light, led street light series, pole series, Chinese lamps series, garden light series, lawn lamp series, a variety of other special series of street lamps, road lighting projects to undertake,

Alloy steel refers to steel with high strength and good chemical stability at high temperature. It includes two types of anti oxidation steel (or high temperature resistant steel) and hot steel. Anti oxidation steel generally requires good chemical stability, but the capability is limited. High temperature strength and the corresponding oxidation resistance of heat and strong steel are required. Heat-Resistance Steel is often used in the manufacture of boiler, steam turbine, power machinery, industrial furnace and aviation, petrochemical and other industrial sectors in the work of the high temperature parts. In addition to the requirements of high temperature strength and high temperature oxidation corrosion, sufficient toughness, good shaping and welding are also required according to the different use, as well as a certain organizational stability. In addition, some new low chromium nickel oxidation are also developed .
