Comparison table of energy saving between solar street light and ordinary street light1

It is calculated based on working 11 hours a day and working time is 5 years. Led adopts dimming energy saving method)

Project data

Traditional 250 High Pressure Sodium Lamp

Solar 60WLEDl Street Light

5 years power consumption

The light source is 250W, the rectifier is connected in series when the start is high current impact processing, so the line and transformer are 15%; every day; 12 hours on; the actual power consumption per day is 3.45KWh, 66 base street lights use 41.56KWH for 5 years

Use solar energy without consuming electricity

5 years to pay the electricity bill

Calculated at 0.80/kWh, the 5-year electricity bill for 66-base street lights is 332,500

No need to pay electricity bills

5 years maintenance fee

1. Change the light source twice: 66 base*100 yuan/baseu003d6600

2. The timer, fuse, electronic starter, and rectifier are replaced every 3 years, the cost is approximately: 66*200 yuan u003d 13200 yuan; the total maintenance cost for 5 years: 19,800 yuan

LED street lights can realize intelligent dimming schemes, which can effectively extend the life of the system. Its service life is 6-8 years. It does not need to be replaced and repaired within five years.

Total cost for 5 years
