The size of a solar panel has a lot to do with the street lighting use it can support. The size of a solar panel is generally determined by its power. The higher the power, the more electricity the solar panel can provide and the longer the street light can be used.
Generally speaking, a regular floor lamp requires between 30 watts and 100 watts. Suppose we choose a solar panel with a power of 50 watts, then the power it can provide is 50 watts. Under ideal circumstances, the solar panel can receive 6 hours of sunlight per day, so the power it can provide per day is 50 watts * 6 hours = 300 watt hours.
Next, we need to calculate the daily power required by a street light. Assuming a street light consumes 50 watt hours of electricity per day, a solar panel with an output of 50 watts can support the use of a lstreet light for 300 watt hours / 50 watt hours = 6 hours.
It should be noted that the above calculations are carried out under ideal conditions. Considering factors such as solar panel efficiency and weather conditions, the actual situation may be different. In addition, the power and usage time of street lights also vary depending on region, demand and other factors. Therefore, in practical applications, it is necessary to select the appropriate solar panel size and street lighting power according to the specific situation to ensure that the street lights can be used normally.
Solar street light panel lithium battery lead acid battery calculation method
Solar street light is a lighting device that uses solar energy to generate electricity . It converts solar energy into electrical energy throughsolar energy. panels then stores it in a lithium battery for night lighting. According to the conditions given in the question, we need to calculate the capacity of lithium batteries required to meet the needs of solar street lights.
First, we need to calculate the total daily energy consumption of solar street lights. According to the conditions given in the question, the light source power of the solar street light is 30W and lights up for 6 hours. Therefore, the daily energy consumption is 30 W * 6 hours = 180 Wh.
Next, we need to calculate the energy consumption of solar street lights on rainy days. According to the conditions given in the question, solar street lights should stay on for 7 hours on rainy days. Since there is no solar power supply on rainy days, the power supply must depend on stored electricityin lithium batteries. Let's assume that the energy consumption on rainy days is the same as on sunny days, i.e. 180 Wh per day. Therefore, the energy required on rainy days is 180 Wh * 7 hours = 1260 Wh.
In summary, the total energy consumption of solar street lights per day is 180Wh + 1260Wh = 1440Wh.
Next, we need to calculate the lithium battery capacity needed to meet the needs of the solar street lights. Generally speaking, the capacity unit of a lithium battery is ampere-hour (Ah), which is how long the battery can supply power when the current is 1A. We can calculate it by the following formulaRequired lithium battery capacity:
Lithium battery capacity (Ah) = total power consumption (Wh) / voltage (V)
According to the question, the voltage of the solar street light is not indicated, generally the voltage ofThe solar street lights are 12V. Therefore, we can set the voltage to 12V and substitute it into the formula to calculate:
Lithium Battery Capacity (Ah) = 1440Wh / 12V = 120Ah
By Therefore, a lithium battery with a capacity of 120 Ah is required in order to meet the usage needs of solar street lights.
In summary, according to the conditions given in the question, the 30W light source of the solar street light can last 6 hours and 7 rainy days, and it should be equipped with a lithium battery with a capacity of 120Ah.
The solar street light is a lighting device that uses solar energy to produce electricity. The panel is the key element that converts solar energy into electrical energy. Battery is a device that stores electrical energy, and the most common ones include lithium batteries and lead acid batteries. The following will present the methods for calculatinglithium batteries and lead acid batteries for solar street lighting panels.
First of all, we need to calculate the battery capacity required for solar street lights. Battery capacity refers to the electrical energy it can store, usually in amp hours (Ah). The calculation formula is:
Battery capacity (Ah) = Electric energy required by solar street lights (Wh) / Battery voltage (V)
Among them, l Electrical energy required by solar street lights Solar street lights can be calculated using the following calculation formula:
Electrical energy required by solar street lights (Wh) = daily working hours of solar street lights (h) × power of solar street lights (W)
Daily working hours of solar street lights. They can be adjusted according to the actual situation, generally 8-12 hours. The power of floor lampsAreas can be selected based on specific models and needs.
Next, we need to calculate the panel capacity required for the solar street lights. Panel capacity refers to the solar energy the panel can convert, usually in watt hours (Wh). The calculation formula is:
Panel capacity (Wh) = Electrical energy required by solar street lights (Wh) / Conversion efficiency of solar panels
The conversion efficiency of Solar panels refer to solar energy. energy The electrical energy efficiency of solar panels is generally 15 to 20%.
Finally, we need to choose the appropriate battery type. Lithium batteries and lead-acid batteries are common types of solar street light batteries. Lithium batteries have the advantages of high energy density, long life and light weight, but are more expensive; beat themLead-acid ies are cheaper, but larger and heavier. Choose the appropriate battery type based on actual needs and budget.
In summary, the calculation method of lithium batteries and lead-acid batteries for solar street light panels mainly includes the calculation of battery capacity and panel capacity, as well as selecting the appropriate battery type according to actual needs.
