Which city in Lanzhou, Guiyang, Haikou or Kunming is not suitable for promoting solar street lightin

Among the four cities of Lanzhou, Guiyang, Haikou and Kunming, Guiyang is relatively unsuitable for the promotion of solar street lighting.

First of all, Guiyang's climate is characterized by cloudy and rainy weather, with relatively little solar resources. Solar street lights require enough sunlight to charge to ensure normal use at night. However, Guiyang has high cloud cover and relatively short sun exposure time, which limits the charging effect of solar street lights and may lead to unstable lighting at night.

Second, Guiyang experiences heavy rainfall, and rainwater may affect the normal operation of solar street lights. Solar street lights are usually installed outdoors and are easily soaked and corroded by rain, which may cause short circuits or other failures, affecting their normal lifespan.

Third, the temperature in Guiyang is relatively low, especially in winter. Solar street light batteries must operate within a certain temperature range. Too low temperature may cause battery performance to decline, affecting the charging effect and night lighting time of solar street lights.

Finally, the size of Guiyang city is relatively small and the demand for road lighting is relatively low. The promotion of solar street lights requires certain investment and maintenance costs. If the city's demand for road lighting is not high, the promotion of solar street lights may not generate economic benefits.

In summary, relatively speaking, Guiyang is not suitable for the promotion of solar street lights. Of course, this does not mean that Guiyang is completely unsuitable for using solar street lights, but compared to cities like Lanzhou,Haikou and Kunming, Guiyang's climatic characteristics and city size may have certain consequences on the promotion and use of solar street lights. lights.
