Solar streetlight installations should be located in areas with good drainage around them. If there are rivers or puddles within a 10-meter radius, the water level must be at least 2 meters below the ground surface. The surrounding area should be free of obstructions (determined by the height of the lighting fixtures) and hazardous items such as high-voltage lines; and there should be no public utilities like cables, optical fibers, or drainage pipes underground at the installation site.

Construction personnel have the responsibility to question the rationality of the installation site selection based on the site conditions, stop the construction if necessary, and promptly report the situation to the relevant responsible person.

Before construction, prepare the necessary tools for making the foundation of solar streetlights and select construction personnel with experience; strictly choose suitable cement according to the solar streetlight foundation diagram; in areas with high soil acidity and alkalinity, special acid-resistant and alkali-resistant cement must be used; ensure that fine sand and gravel are free of soil and other impurities that affect concrete strength; excavate the foundation pit strictly according to the dimensions of the solar streetlight foundation diagram (determined by the construction personnel) along the road direction; after the excavation is completed, leave it for 1 to 2 days to check for any groundwater leakage.

In case groundwater leaks, construction must be halted immediately; the bottom of the trench where the battery compartment is placed in the foundation must be fitted with 5 x Ф80 drainage holes or as per the design drawings. In the foundation, the upper surface of the embedded cage must be ensured to be level (measure and inspect using a level), and the foundation bolts in the cage must be perpendicular to the foundation's upper surface. Installation of solar streetlights can only proceed after the foundation for the solar streetlights has been inspected and approved.
