With the advancement of photovoltaic technology, the use of solar energy has become more and more widespread, and many rural street lights also use solar energy. Solar led outdoor light has been widely used in rural areas. However, the price of solar led outdoor light on the market is not balanced, mainly because there is no uniform configuration standard. Some configurations are high, and naturally the price is also high. Some configurations are naturally low in price. So why is there no uniform standard for the configuration of solar energy-saving street lights?

Solar energy-saving street light

　　 1. Different regions have different sunshine coefficients

　　In some areas with high solar coefficient, using solar panels of the same power, the solar led outdoor light in that area will charge more. However, in some areas with low sunshine coefficients, the daily charge will be lower. Therefore, compared with areas with high sunshine coefficients, the power of solar panels used will be higher.

　　 2. North-South temperature difference

The lowest temperature in the southern winter will not be minus 10 degrees, so you can use the cheaper 3.2V lithium iron phosphate battery, while the low temperature in the northern winter is not suitable for lithium iron phosphate batteries, you can only use 12V ternary lithium batteries, because the ternary Lithium batteries are resistant to low temperatures.

　　 3. The number of rainy days varies by region

　　 In some areas, there are many rainy days, so in order to ensure that the solar led outdoor light continues to be lit in rainy days, the capacity of the solar lithium battery must be increased. In some areas, there are fewer rainy days, so the capacity of lithium batteries does not need to be that large.

　　 Therefore, from the above three perspectives, it is impossible for solar energy-saving street lights to reach uniform standards in every region. This also leads to the different prices of solar led outdoor light purchased in each region. This is because solar led outdoor light manufacturers match different configurations according to different regions, so solar led outdoor light does not have a unified price standard.
