Solar led street lamp is a classic case of new energy application. It is not only green, but also beautiful, which can improve the city appearance. In addition, solar led is more economical. Such high-quality products should be promoted in basic theory, but in fact, they are not. The coverage of solar led street lamps in china is still very low. What are the reasons for the low coverage of solar led street lamps from a professional perspective?

1. Low brightness of solar led road

First, the brightness of solar led street lamps. Solar led only relies on sunlight for power generation, and the conversion rate of solar photovoltaic panels is only about 19%. Due to the limited output power, it is impossible to do a good job of lighting with high power, so the brightness should not be compared with the power brightness.

2. Solar led street lamps are expensive

Solar led street lamps have a large number of solar photovoltaic panels, rechargeable batteries and control panels than ordinary street lamps. There is no doubt that the production cost is not low, at least 2 to 4 times that of ordinary road lamps. Although it can be repaid within at least 5 years, it can not be estimated in this way sometimes.

3. Short cycle times of lithium battery of solar panel

All solar panel lithium batteries cannot be maintained for too long. This is caused by the technical level of the road lamp industry. It must be replaced after at least 3 years. Therefore, most street lamp manufacturers have a 3-year warranty period. If the rechargeable battery fails, the solar led will also fly over qualitatively.

Even though solar led street lamps have many limitations, they are not hidden. In recent years, they have been widely used. According to statistics, the annual output in 2020 will be around 20 million baht, which is quite extensive compared with developed countries in Europe and the United States. There is another gap. We will continue to increase technical development efforts to make our road lamps ahead of the industry.
