Judge Quality Of Solar Powered Street Light

Whether it is the main road in the city or the small road in the countryside, we can always see solar powered street lights. As a kind of outdoor road lighting, solar powered street lights are welcomed by most people due to their energy saving, environmental protection, huge electricity bill savings, easy installation, and basically no maintenance. Due to the large variety of solar powered street lights sold in the market, the prices vary greatly, resulting in uneven quality of street lights. So, for consumers, when buying solar powered street lights, how should they judge the pros and cons of solar powered street lights?

First of all, we need to have a comprehensive understanding of solar powered street lights. Solar powered street lights do not need to be connected to the grid, and rely entirely on solar lighting, mainly composed of batteries, intelligent controllers, light sources, solar panels, and accessories for light poles. If the price of solar powered street lights is a little lower, at least one or two parts of the complete system will not meet the quality standards. It is not easy to find problems in the short term, but in long-term use, problems will occur.

There are two types of commonly used solar panels, monocrystalline silicon solar panels and polycrystalline silicon solar panels. The conversion rate of polycrystalline silicon solar panels is usually around 16%, and the conversion rate of monocrystalline silicon solar panels is around 21%. The higher the conversion rate, the more electricity can be used for street lamps, and of course the more expensive the photovoltaic panels will be. To ensure a good lighting effect, the battery is also an extremely siginificant component. There are many types of batteries, such as lead-acid batteries, lithium iron phosphate batteries, etc. The lead-acid battery has stable voltage and relatively cheap price, but has low energy and short service life. Lithium iron phosphate batteries have obvious advantages in terms of depth of discharge and charging aging. Generally, it can be used in the environment of -20℃-60℃, and the application environment is relatively wide. The service life can reach 7-8 years, and it is more worry-free to use. Moreover, the volume and weight of the lithium iron phosphate battery are also smaller, and the installation is simple.

Whether the poles of solar power street lamps are hot-dip galvanized or cold-galvanized, the difference lies in the incision. Hot-dip galvanized light pole cutout has coating, cold galvanized light pole cutout has no coating. The life of hot-dip galvanized light poles is generally more than 20 years, while the life of cold-galvanized light poles is generally about 1 year. The controller of the solar powered street light has an irreplaceable position in the solar powered street light system. It is the control center of the solar powered street light. Whether the solar powered street light can work normally depends on it. Its main function is to control the solar panel to charge the battery and control the switch of the street light.

In short, although solar powered street lights are good, the quality of solar powered street lights on the market is uneven. Therefore, when new users buy street lamps, they should examine their pros and cons from many aspects. In addition, a very important point in using solar powered street lights is to choose a good manufacturer, and after-sales service can be guaranteed. You can't just look at the price, and the brand effect is the key.
