How about the performance of solar LED outdoor lights?

In many outdoor lighting projects, there are a large number of outdoor lights using solar energy. During the day, solar panels absorb the energy in the sun and store it in the battery. At night, the LED lights are automatically lit, and there is no need for a penny of electricity. It seems energy-saving and convenient.

So, to what extent has the performance of this solar outdoor light developed, how reliable is it, is the electric energy generated during the day enough to be used at night, and how bright is the light, how high is the installation cost, and is it easy to break? I believe that many friends have these questions before deciding whether to install solar outdoor lights. Below, the editor will introduce the principle and advantages and disadvantages of solar outdoor lights in detail.

The structure and principle of solar outdoor lights

Solar outdoor lights are generally composed of five parts: solar cells, batteries, controllers, light sources and lamp holders.

The working principle of solar outdoor lights is that during the day, the solar cells receive sunlight to generate electricity, and the battery is charged through the intelligent controller, and the electricity is stored in the battery. When it is dark, the intelligent controller turns on the light source. The lighting time and how many rainy days can be used in total depends on the size of the battery. When configuring, you can tell the lamp manufacturer how many hours you will use every day, and how many rainy days in a row, and adjust the size of the battery according to the actual situation. Generally, the battery manufacturer guarantees it for two to three years. . Solar panels are generally guaranteed for more than 15 years. If the lamp body is protected from man-made damage, good quality ones can generally be used for about 15-20 years.

The advantages of solar outdoor lights

1. Energy saving: solar outdoor lights use natural light sources in nature to reduce power consumption;

2. Safety: There may be safety hazards in the outdoor lights of mains lighting due to various reasons such as construction quality, material aging, and abnormal power supply. The solar outdoor lights do not use alternating current, but use batteries to absorb solar energy and convert low-voltage direct current into light energy, so there is no potential safety hazard;

3. Environmental protection: solar outdoor lights have no pollution and no radiation, which conforms to the modern concept of green environmental protection;

4. High-tech content: solar outdoor lights are controlled by an intelligent controller, which can automatically adjust the brightness of the lights according to the natural brightness of the sky within one day and the brightness people need in various environments;

5. Durability: At present, the production technology of most solar cell components is enough to ensure that the performance will not decline for more than 10 years, and the solar cell components can generate electricity for 25 years or longer;

6. Low maintenance cost: In remote areas far from towns, the cost of maintaining or repairing conventional power generation, transmission, street lights and other equipment is very high. Solar outdoor lights only require periodic inspections and little maintenance workload, and their maintenance costs are lower than conventional power generation systems;

7. Building blocks of installation components: flexible and convenient installation, which is convenient for users to choose and adjust the capacity of solar street lights according to their needs.

Disadvantages of solar outdoor lights

1. The initial installation cost is relatively high

Due to the investment of solar panels and batteries in solar outdoor lights, the cost is 3 to 4 times higher than that of ordinary lighting fixtures.

2. The service life of the battery is short

The battery is also a short board, generally only has a service life of two to three years. After that, the energy storage will decrease and the lighting time will be shortened. In the end, it must be replaced, which increases the later use cost. However, from the perspective of the whole life cost of solar outdoor lights, it is still much smaller than the cost of traditional lamps. Because in the later use, the power consumption of solar outdoor lights is 0.
