Solar street light panels regularly calculate solar lamp remote storage

A, thinking: 1. Local install solar street lights in guangzhou as an example, the way of thinking, work through the street lamp power and time to calculate the daily power consumption, and then through the peak of sunshine time each day to calculate the solar panel power, and calculate the loss and rainy day. Storage



a, thinking:

1. In guangzhou local install solar street lamp, for example, thinking: 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 a long rainy day and a night to power.

2. Solar energy usually do 1 working voltage of the battery. Five times the recharge a better match.

3. Look-up table is guangzhou average sunshine time is 3. 52 hours: suppose street lamps of 80 w

LED street lamp, working 11 hours a day, six hours at full power, power of 5 hours and a half. The daily power consumption is: 80 w / 24 v * ( 6 5/2) = 28. 34 a 6 5/2 for 6 hours at full power

5 hours and a half power.

2, solar panels to calculate

solar panel 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.

3, the capacity calculation of battery, battery work with 24 v voltage, capacity of: 28. 34A*( 5

1) 【 = 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.

4, installation Angle: usually installation Angle for the local latitude, better installation Angle is in the south by west.

the solar energy is hydrogen atoms [in-house Hydrogen atoms that hydrogen atoms. 】 Fusion [ Fusion belongs to the modern word, refers to the quality of small atoms, deuterium and tritium, for example, under certain conditions, Such as ultra-high moderate high pressure) Each other, the nucleus polymerization, neutrons and helium - 4, with huge energy release of a form of nuclear reactions. 】 Releasing huge nuclear power, as a result of the radiation energy from the sun. Human required for most of the solar energy directly or indirectly from the sun. Plants through photosynthesis release oxygen and absorbing carbon dioxide, and convert solar energy into chemical energy in plant body storage down. The fossil fuels such as coal, oil, natural gas Fossil fuels also called fossil fuels, is a derivative of the hydrocarbon and hydrocarbon mixture, which include natural resources such as coal, oil and natural gas, is made up of dead organic matter and formed by the decomposition of plant in the ground, is non-renewable resources. 】
