Loss of circuit to create city light

1. The installation procedures and operations are very complicated. It requires laying cables, digging trenches to place cables, laying underground pipelines, threaded pipes, backfilling and other major infrastructure projects. The installation and commissioning site and online material requirements are more complicated, and labor and support costs are high.

2. Expensive long-term continuous lines and other repair or replacement modes, and annual maintenance costs.

3. There are safety risks, because of the quality of construction and renovation of landscape architecture, aging materials, electricity is abnormal, water pipes and electricity conflicts with other things have caused many safety risks.

4. Using circuits to create the city's light, the average life span is about 10,000 hours, and the longer the life span, the aging of the pipeline.

5. At the largest scale, the high cost and total investment of the city's lighting installation and use of circuits will exceed that of solar street lights. Another stolen cable cannot estimate the annual loss. The advantages of all solar street lights are obvious.
