The main reasons why solar lights are more expensive than mains lights include the following:

‌High initial investment cost‌: Solar lights contain multiple components such as solar panels, batteries, LED lamps, controllers, and light poles. The manufacturing cost and technical content of these components are high, resulting in an overall price increase. For example, a set of medium-configuration 6-meter solar street lights may cost about 1,900 yuan, while the cost of mains lights of the same height is about 700 yuan.

‌Technical content and material cost‌: Solar lights integrate solar power generation, LED lighting, and intelligent control technology to increase added value. The cost of materials such as solar panels and batteries used is high, which also pushes up the overall price.

‌Low maintenance cost in the later stage‌: Although solar lights have a large initial investment, their later maintenance cost is relatively low. Since they do not rely on power supply from the grid, maintenance caused by power outages or grid failures is reduced. At the same time, LED lamps have a long life and reduce the frequency of replacement.

‌Energy consumption and environmental protection characteristics‌: Solar lights generate electricity through solar energy, reducing the consumption of traditional energy and contributing to sustainable development. Although the initial investment is high, in the long run, the energy-saving benefits are significant and the investment is worthwhile.
