With the more and more global emphasis on new energy fields, the photovoltaic industry is also in the stage of expansion and popularization, the use rate of LED solar street light is gradually increasing, and are very popular especially in industrial parks, factories, rural roads and other places.
Solar street light is generally composed of solar controller, solar panels, batteries, light poles, light fixtures and other components, of which solar controller is the core components of solar powered led street light. According to market demand, PWM-type solar controller, MPPT solar controller, wind and solar hybrid solar controller, thin-film panel MPPT-type controller and micro-landscape lights controller are appeared on the current market.
What are the advantages and disadvantages of solar street lights? This article will briefly analyze its advantages and disadvantages.
At first, LED solar street lights are relatively safe, use 12V power supply, not easy to cause electric shock, and ordinary street lights with 220V voltage, once occur the situation of leakage or short circuit, it may cause casualties. Then the solar street lights installation process is relatively convenient, without complicated line construction, no need to set up the antenna or cable, just find the right location, trenching and mounting lights, relatively beautiful and convenient.
Second, the life of solar street lights is generally 5 years, with the progress of photovoltaic technology, service life will be longer and longer, and ordinary street lights life is only 2 years.
Finally, solar lights will convert solar energy into electricity energy, energy saving and environmental protection without pollution.
Technology is a double-edged sword, solar street lights have many advantages, but there are some shortcomings should be improved.
Purchase cost of solar street lights is several times higher than ordinary street lights price, followed by China has no unified standard to measure the quality of the solar street light.
Power supply time of solar street power has certain limitations, if there is a long rainy days, then most likely without lighting because insufficient power supply.
Solar street light is the application trend in future, with the improvement of customer demand and photovoltaic technology breakthrough, the future market is not only appears PWM-type solar controller, MPPT solar controller, solar hybrid solar controller, thin-film panel MPPT-type control And micro-landscape lights controller, there will be more controllers developed to further improve the solar street light system.
