solar street light VS other ordinary electric street light

At present, our common and commonly used street lights are mainly solar street lights and mains electricity street lights two types, many people are not particularly clear about the difference between the two. Today, we will do a simple comparison of the installation, cost, stability, and several other common problems.

1. Installation Comparison

In the installation, solar street lights do not need to be supplemented with complex wiring, only a concrete base and a battery pit within 1m, fixed with galvanized bolts can be made.

Mains electricity street lights construction has a complex operation procedure. First of all, the installation of utility street lights requires auxiliary cables, digging trenches and laying pipes, pipe threading, backfilling, and a lot of civil construction, consuming a lot of manpower, material, and financial resources. After the end of the installation of mains electricity street lights also need to be commissioned, once the problem, they will cause a lot of consumption.

2. Cost Comparison

Solar street light is a one-time investment and long-term benefit. Solar power generation, no expensive electricity bills, easy wiring, no maintenance costs. With solar street lights, you can recover the cost in 6 to 7 years, and save more than 1 million in electricity and maintenance costs in the next 3 to 4 years.

Mains electricity street lights have high electricity costs, and complex wiring and require long-term uninterrupted maintenance of the wiring. Especially in the case of unstable voltage, sodium lamps are prone to break down inevitably, and with the extension of the years, the line aging, and maintenance costs are increasing year after year.

3. Protection comparison

Solar street lights use 12-24V low voltage, stable voltage, reliable operation, and no hidden dangers are the ideal choice for road departments and ecological communities.

Mains electricity street lights have big hidden dangers, and people's living environment is constantly changing, and the construction of road renovation and landscape projects, irregular power supply, and cross-construction of water and gas pipelines are easy to bring many hidden dangers in many aspects.

4. Environmental Protection Comparison

Solar street light reduces power consumption, save power resources, and are in line with the concept of environmental protection. In addition, it can sustainably reduce property management costs, reduce the cost of the owner's public share part, and can add new selling points for the development and promotion of noble ecological communities. In summary, the inherent characteristics of solar lighting such as no hidden dangers, energy saving, no consumption, green environmental protection, easy installation, automatic control, and maintenance-free will bring obvious available advantages for the construction of municipal projects and sales of buildings directly.

5. Lifespan comparison

The life span of solar street light is much higher than that of ordinary electric street light, such as the life span of solar cells, the main component of solar street lights, is generally 25 years; the average life span of low-pressure sodium lights is 18,000 hours; the average life span of low-voltage trichromatic energy-saving lights is 6,000 hours; the average life span of super bright LED lights is more than 50,000 hours. The life span of solar batteries is 2 to 5 years for 38Ah batteries; 3 to 7 years for 38-15Ah batteries.

In accordance with the provisions of the maintenance costs of street lights, making the initial investment in ordinary electric street lights is much higher than the initial investment in solar street lights. In short, in a comprehensive comparison, the use of solar street lights for environmental protection and investment-saving features are quite obvious.

In solar power supply systems, the performance of the battery directly affects the comprehensive cost, operation, and service life of the system. The lithium iron phosphate battery used in solar power supply systems by Yahua Lighting has the following outstanding features in the design and manufacturing process compared with the ordinary lead-acid battery.

(1) Large capacity

The lithium iron phosphate battery has a larger capacity than ordinary batteries (lead-acid, etc.), known by the capacity density of the battery, the energy density of lead-acid batteries is about 40WH/kg, the market mainstream lithium iron phosphate batteries, and energy density are to do more than 90WH/kg.

(2) Good safety performance

The lithium iron phosphate battery cathode material's electrochemical properties are relatively stable, which determines that it has a smooth charge and discharge platform. Therefore, the structure of the battery will not change during charging and discharging, will not burn and explode, and is still very safe even under special conditions such as short circuit, overcharge, extrusion, pinprick, etc.

(3) Long cycle life

The lithium iron phosphate battery 1C cycle life is generally up to 2000 times, or even up to 3500 times, and for energy storage market requirements to reach more than 4000-5000 times to ensure a life of 8-10 years, higher than the cycle life of ternary batteries more than 1000 times, while the cycle life of long-life lead-acid batteries in about 300 times.
