As far as the product itself is concerned, the manufacturing cost of solar light is higher than that of ordinary lights. In the actual situation, if the cost of the whole construction process of the solar outdoor light manufacturer is taken into account, the cost of ordinary lights will be higher.

The larger the scale, the more expensive the installation of ordinary lights. The initial investment will be higher than solar lights.

In terms of operating cost, the cost of ordinary lights is much higher than that of solar lights, and the cost will be higher and higher (kilowatt-hour cost and labour cost).

In terms of safety, solar-powered led street lights use DC below 36V, which will not cause any safety problems. As ordinary lights use AC power, wires may age, which will cause serious safety problems.

The service life of solar lights is much longer than that of ordinary lights. For example, the main components of solar lights (solar cell modules) have a service life of more than 20 years.

If the ordinary light is scraped off after 10 years of use, the whole light will be scrapped. The cable will also have ageing problems; And does not meet the requirements of new lights. If the solar light is scrapped after 10 years of use, the battery will continue to be used (the service life reaches 25 years). The solar battery is the most expensive component in the solar light (accounting for more than 60% of the total manufacturing cost).

With the increasing shortage of energy today, the cost of cable and kilowatt-hour for ordinary street lights will continue to rise. The installation and maintenance costs of ordinary lights will be higher and higher.

To sum up, solar lights meet the needs of social development and environmental protection and have remarkable economic and social benefits.
