How do solar street light led lamp light to calculate the power?

How to calculate the solar street lamps power? 1. Install solar street light in guangzhou as an example, the train of thought to embellish lighting supply: work through the street lamp power and time to calculate the daily power consumption, again through the peak of sunshine time each day to calculate the solar power generation work



the solar street lamps Solar street light is a crystalline silicon solar battery power supply, valve control type sealed and maintenance-free battery ( Gel battery) Store electricity, super bright LED as light source, lamps and lanterns and controlled by the intelligent charging and discharging controller, is used to instead of the traditional public power lighting lamps. 】 How to calculate the power?

1. Install solar street light in guangzhou as an example, the train of thought to embellish lighting supply: work through the street lamp power and time to calculate the daily power consumption, again through the peak sunshine every day 【 Peak sunshine time is a description of the sun's radiation unit ( W / ㎡ / days namely watts per square meter per day) , also known as the sun relative sunshine duration or relative sunshine duration. 】 Time to calculate the solar panels 【 Solar cell is also known as 'solar cells' or 'cell', is a kind of electricity generation by using sunlight directly photoelectric semiconductor wafer. 】 Power, and calculate the loss and rainy day. Battery capacity' Battery in the prescribed conditions ( Including the intensity of discharge termination voltage, discharge current and discharge) Sent out how much electricity or discharge duration called battery capacity, unit or a. a. h min. 】 For the longest rainy day and a night to power. 2. All the working voltage of solar do 1 for battery. Five times as the best charging collocation. 3. Look-up table to obtain the average sunshine time in guangzhou is 3. 52 hours: assume that street lamp is 80 wled street lamp' LED street lamp is made of street lamp, LED lamps and lanterns with high efficiency, safety, energy saving, environmental protection, long service life, fast response speed, high color rendering index of unique advantages, the city lighting energy saving is of great significance. 】 , work 11 hours a day, shandong cape lighting electric co. , LTD. Is engaged in the production design of solar street light, high lamp factory, 20 years production experience, solar street lamps to build the most professional manufacturer of solar street lamps, 13805257308. Full power, 6 hours, 5 hours and a half power. The daily power consumption is: 80 w / 24 v * ( 65/2) = 28. 34 a65/2 full power 5 hours and a half power for six hours. Second, the solar panels to calculate solar panels need power: every day 28. 34 * 34 v = 963。 The theory of 56 w, the solar panels power is: 963. 56W/3. 52 = 273. 74 wp, but solar panels to calculate loss 20%, assuming that guangzhou met rainy day, 5 days every 20 days, 20 days of electricity to meet the needs of the 25 days. The power is: 273. 74 * ( 25/20) / 0. 8 = 427. 7 wp。 Choose 2 pieces of 34 v 220 wp solar panels. Three, battery capacity calculation: the working voltage of battery with 24 v, capacity of: 28. 34A*( 51) 【 = 170 a, according to the discharge depth In the process of the battery, the capacity of the battery out of its rated capacity percentage is called the depth of discharge. 】 The 80% computation, the actual capacity to choose 170 a / 0. 8 = 212 a battery can.
