Many customers have received inquiries about solar street lamps, including "how much is solar street lamp", "solar street lamp price", "what price is solar street lamp", "price of a full set of solar street lamps", and so on. Customers who don't know much about solar street lamps often don't know that different configurations and prices are different, because it's not a standard product.
In fact, the solar street lamp can be divided into several major parts, and the relevant parts can be selected according to the customer's own requirements before the normal quotation can be made. We need to know the height of the lamp pole, the power of the LED lamp, the continuous working time of the street lamp, etc. before we can offer customers a reasonable price for the solar street lamp. (the solar lamp brother takes great pains to instill solar energy configuration problems into customers, ha ha!)
The customer needs to know the width of the road and the spacing between the lamp poles to calculate the height of the lamp pole and how much power the lamp has; Then light up a few hours a day to meet the number of rainy days, and then we calculate the size of the lithium battery. With this information, it is convenient for us to quote.
Today we teach all users a cost accounting method, which is simple and practical!
Solar street lamps are mainly divided into five parts: solar panel (power generation device), battery system (including controller device), LED light source (lighting device) and lamp pole (support device).
Solar panel: 3-4 yuan per watt, 300 yuan for 100W / 18V panel; If the power of each board is less than 50W, it needs 3.5 yuan per watt;
Battery: lithium battery: 15 yuan per ah, 750 yuan for 50ah, including the controller (the product structure of lithium battery and controller); The price of lead-acid battery is 8 yuan per ah, and 50ah is 400 yuan (the price of lead-acid battery is cheap, but the service life is only 3-5 years, and the construction cost is high. The internal resistance of lead-acid battery is large, and it is difficult to charge in cloudy days.
Lamp pole: hot dip galvanizing process of conical lamp pole: for a 6-7m high lamp pole, it is about 80 yuan per meter; for 8-9m, it is 100 yuan per meter; the higher the height, the higher the cost per meter. The cost of solar street lamp and solar panel support is about 60 yuan; for example, the lamp pole accessories of a 6m solar street lamp are 540 yuan, including earthworm.
Lamps; conventional solar street lamps are 4 yuan per watt, for example, 30W lamps are 120 yuan.
The above total is basically the cost of a solar street lamp.
This calculation method can be used as a cost reference. For example, the purchase quantity of the project is relatively large, it can also be discussed in detail.
