Comparative analysis of solar street lights and ordinary street lights

1. Comparative analysis of solar street lamps ** and ordinary street lamps:

First, the traditional street lamp needs to lay wires when it is installed, and the device is also very complicated, and there is a complex operation sequence in the mains lighting street lamp project. From the excavation of the cable trench, laying the hidden pipe, threading in the pipe, backfilling, etc., are a large number of foundation works. After that, there is a long commissioning process.

A lot of manpower and material resources are wasted in the installation process. The solar street lamp installation is simple, no need to lay complex lines, just make a cement base, and then fix it with stainless steel screws.

Second, traditional street lamps have potential safety hazards, due to the construction quality, the transformation of landscape engineering, the aging of components, abnormal power supply, and the conflict of water and electricity pipelines. Solar street lamps mainly absorb solar energy and have high safety.

Third, traditional street lamps need to be temporarily and continuously maintained or replaced with lines and other configurations, which consumes material and financial resources. The maintenance interest increases year by year. Solar street lamps do not need to use electricity bills when they are used, and solar street lights are a one-time investment, which can recover the investment cost in three years and benefit temporarily.

The operation of solar street lights is safe and reliable; And it's green. There are no safety hazards, and the various selling points of solar energy are valuable.

Second, a little better solar street lamp is still recommended to order on the solar ** portal, there are most of China's street lamp companies, you just need to simply publish a purchase there are a large number of manufacturers for you, if you want to be more assured, you can enter the group bargaining page, the finishing process does not need to worry.

Solar street lights are safer, and the simple installation cost should be that solar street lights are expensive, but in the long run, solar street lights are more cost-effective and environmentally friendly.

Insufficient solar energy.

1.Batteries are expensive, and they need to be replaced in 2 to 3 years, and 1000 charges and discharges have exceeded the limits of the battery. Ordinary batteries are 300 500 times. If you use it very properly, 1000 times is theoretically fine, but it is already 1095 times in 3 years.

Battery Replacement:

1500*250=375000 (10,000)."

The calculation is incorrect. The power consumption for one day is 4 degrees, and the required battery capacity is 4 degrees for 4 days and 16 degrees for 4 days. (If you want to meet the situation that you can supply power for 3 consecutive rainy days).

How much does a battery that can store 16 kWh of electricity cost? My electric car battery power is 20ah*48v=960vah=degree and the weight is 30kg.

Valued at $450. If you trade in the old for the new, it will cost 300 yuan. Switching to a street light battery requires 16 times the capacity of an electric vehicle.

The new one costs 7,200 yuan and weighs 480 kilograms. The trade-in costs 4,800 yuan. 4800 yuan is just the cost of replacing the battery once.

You need to replace the battery at least 4 times in 15 years, and the cost of replacing the battery in 15 years alone is 19,200 yuan. I haven't calculated the labor cost with you yet.

He only gave you 1,500 yuan, not even a tenth!

Lampheads are also ridiculously expensive. If it breaks, it's a tragedy. Solar cells are not too expensive, 100 watts of 300 yuan, a day can absorb solar energy. Degree. 4 kWh of electricity requires 8 such batteries, and it is only 3,200 yuan. It is said to be available for 25 years.

But you are not given the cost of cleaning the solar cells, if they are not cleaned, the solar cells are full of dust, how to generate electricity?

The remaining electricity cost for using solar street lights is 4 365 15 21900 yuan than the cost of replacing the battery is 2700 yuan, which is almost exactly the labor cost of replacing the battery, 700 yuan at a time, so many batteries are shipped and then installed on 700 It is difficult to say that it is not enough.

The conclusion is that if your battery is good enough to be perfect, it only needs to be replaced 4 times. If you never clean the solar panels and completely rely on rainwater to rinse, there is that your LED lamp head worth thousands of yuan will not be bad for 15 years. So much if all are true.

Congratulations, your solar street light will cost the same as ordinary street light for 15 years.

But after a little longer, you will find that you will lose a lot when you replace the LED lamp head and the solar panel!

And don't forget that your solar street lights are more than 11,000 more expensive than regular street lights! That is to say, if everything is perfect, your solar street light will be more than 10,000 yuan more expensive than the installation and use cost of ordinary street lights in 15 years. Of course, after 25 years, it will be much more expensive to replace the lamp head and solar panels, which is more expensive than replacing the entire street lamp!

Speaking of safety, there are not many cases where street lights electrocute people. Street lights are not lit, robbery, and the chances of traffic accidents are higher. Don't forget that this solar street light is designed to be rainy for 3 days, plus the electricity used the night before is 4 days, if it is more than 3 days of rain, your solar street light will not be lit!

The robbers can watch it rain for 3 consecutive days and come to rob the next night.

If you need to add the number of days. The battery is very expensive, and the photocell will cost 14,400 yuan if it rains continuously for 7 days.

Solar street lamp uses sunlight as energy, solar panels charge the battery during the day, and the battery supplies power to the load at night, without complex and expensive pipeline laying, the layout of the lamp can be adjusted arbitrarily, safe, energy-saving and pollution-free, without manual operation, stable and reliable, saving electricity and maintenance-free. Safe & Reliable! - Bright room lighting.

Advantages of solar street lights:

1) Complex installation of mains lighting street lamps: In the mains lighting street lamp project, cables must be laid first, and a large number of basic projects such as cable trench excavation, laying dark pipes, pipe threading, and backfilling are required. Then carry out long-term installation and commissioning, and if there is a problem with any line, it will be reworked in a large area.

In addition, the terrain and route requirements are complex, and the cost of labor and auxiliary materials is high. Solar street lights are easy to install: when solar energy is installed, there is no need to lay complex lines, just make a cement base, and then fix it with stainless steel screws.

2) The high electricity cost of mains lighting street lights: the work of mains lighting street lamps needs to pay fixed and high electricity bills, and long-term uninterrupted maintenance or replacement of lines and other configurations, and the maintenance cost increases year by year. Solar street lamps are free of electricity:

Solar street lights are a one-time investment, without any maintenance costs, and benefit in the long run.

3) There are potential safety hazards in mains lighting street lamps: mains lighting street lamps will bring many potential safety hazards in terms of construction quality, transformation of landscape engineering, aging materials, abnormal power supply, and conflicts of water and electricity pipelines. Solar street lights have no safety hazards:

Solar street lights are ultra-low voltage products, which are safe and reliable in operation. Other advantages of solar street lights: green and environmentally friendly.

To sum up, solar street lamps have the characteristics of safety and no hidden dangers, energy saving and no consumption, green environmental protection, easy installation, automatic control and maintenance-free.
