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

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.
