Take the 10KM main road project in an ordinary city in China as an example to compare the cost of solar LED street lamps and ordinary electric street lamps. At present, the standard main road 100W street lamp installation distance is 30 meters (in fact, BIGGESTNE’s high lumen value and lens configuration can make the installation distance reach 50 meters), 334 one-way roads, a total of 668 street lights.

1.  First time invested. According to 668 street lamps, LEDs are referenced for products with an average quality or higher. From the comparative data, the cost of the first input, solar street lights because of the higher cost of the lamps, the cost is slightly higher than the power street lights.

2.  The cost during the warranty period. At present, the street lamp generally has a shelf life of one to two years, and BIGGESTNE can provide a three-year warranty for the whole lamp. During the 3-year warranty period, it is calculated according to the lighting time of 12 hours per day.
A. BIGGESTNE’s solar street lights can provide 10 continuous lights above rainy days, so in countries with temperate zones, it can ensure continuous lighting for 365 years. 0 electricity expenses.
B. The electricity consumption of electric LED street lamps for 3 years is (100W*12*365*3)/1000*668=877752 degrees, calculated according to the Chinese price level of 0.15$/kWh. The total electricity cost is 131662.8$.

The above is the pure installation cost and the use of the 3-year warranty period. On the whole, the total cost of the solar road is 327,320 US dollars, and the total cost of the power LED is 409,863 US dollars. Power street lights are 25% higher than solar street lights. Considering the use of electricity bills in subsequent years, this cost comparison will only get bigger and bigger.

In addition to the cost items, the advantages of solar street lights compared to ordinary electric street lights are also more obvious.
A. Easy installation: All in one solar street light can be installed in one step, no need to dig, embed, backfill, save construction costs; also have power outages, power cuts, and more advantages in places where there is no electricity.
B. Less comprehensive investment. There is no need to purchase power capacity-increasing equipment, which saves the cost of the equipment. There is no need to track maintenance, and the operation and maintenance costs are low.
C. Safe to use. The tributary voltage is 12V~36V, no electric shock or fire accident occurs, no electric shock will occur, and the use is safe.
D. Energy saving. Requiring energy from the sun, not using conventional electric energy, providing electricity with solar energy conversion, inexhaustible, and saving operating costs.
E. Environmental protection. No pollution, no noise, no radiation.
F. Long service life. Using LED light source, the service life is about 100,000 hours, DC low voltage, long-term durability.
G. Wide application. It can be used in places where there is sunshine.
H. The recycling value is large, and the replaced solar panels and batteries can be recycled and reused.
I. High grade. Green, environmental protection, energy saving, and high technology are symbols of the use of unit image and taste.

A. The solar cell module is exposed to direct sunlight and avoids obstructions. The specific installation location is limited.
B. The initial investment cost of a single lamp is slightly higher without considering the costs of construction, operation, maintenance, etc.
B. In areas with high dust or severe snow accumulation, solar panels are insufficiently exposed to sunlight and their use is limited.
