What are the factors that cause the price difference of solar power source for outdoor lighting?

  The cost of solar power source for outdoor lighting is relatively high. But now there are some low-cost solar power source for outdoor lightingon the market. Many people compare these solar power source for outdoor lighting. It is not difficult to find that solar power source for outdoor lighting with different prices are still very different. The construction of solar street lighting system seems to be simple, but there are many details that are precisely the source of the difference.

  Due to the increasingly fierce price war, some solar street lighting system products have a price difference of 2-3 times. Many users are blinded at the moment and do not know where the price difference comes from. The main reasons for the price difference are the following:

1 brightness

  The headlights of solar street lighting system have different brightness and different prices. This is believed to be easy to understand. Just like traditional incandescent lamps, the price of high wattage lamps is high, and the brightness of solar street lighting system is expressed using lumens. The higher the lumens, the brighter the integrated solar led street light and the more expensive they are.

2 antistatic ability

  The integrated solar led street light with strong antistatic ability has a long service life and is therefore expensive.

3 wavelength

  The integrated solar led street light with the same wavelength have the same color. If the required color is consistent, the price is high. It is difficult for manufacturers without LED spectrophotometers to produce pure color products.

4 leakage current

  LEDs for integrated solar led street light are unidirectionally conductive illuminators, and if there is a reverse current, they are called leakage. LEDs with large leakage currents have short life and low price, and the price is high.

5 illumination angle

  Different solar switch for street lighting may have different illumination angles. Special lighting angle, the price is higher. Such as full diffusing angle, full light distribution, 360 ° lighting, etc., the price is higher.

6 life

  The key to solar switch for street lighting of different price and quality is life, and the life expectancy is determined by light decay. Low light decay, long life, long life and high price. The average life of solar switch for street lighting is higher than that of traditional lamps.

7 LED chip

  The illuminants of LEDs used in solar switch for street lighting are chips, and the prices of different chips vary greatly. The chips in Japan and the United States are more expensive, and the price of LED chips from Taiwanese and Chinese manufacturers is lower than that of Japan and the United States. Most of the price of LED lights is concentrated on the chip, and the chip is equivalent to the heart of LED lamps. Mars solar switch for street lighting uses the Puri double-core LED chip with high brightness and good stability.

8 chip size

  The size of the chip is expressed by the side length. The quality of the street light using solar panel of the large chip is better than the street light using solar panel of the small chip, and the price is proportional to the chip size.

  The price of street light using solar panel generally shows a downward trend, but for low-priced street light using solar panel, consumers must pay more attention to avoid being deceived by unscrupulous merchants. Low-cost street light using solar panel may be manufactured with inferior materials and rough processes, which are not only unsafe in terms of safety, but also doubtful in terms of product quality. Therefore, when consumers choose solar light street light, they must see the product parameters and product quality, and don't want to be cheap.
