Where is the solar street lamp manufacturer in Tianjin?

The design of solar street lamp system mainly refers to the annual average sunshine index of the installation site, the length of continuous rainy days in the local area, the height of lamp post, the power of light source and the lighting time every day. Knowing these can scientifically calculate the configuration of solar street lamp system, and thus reasonably calculate the price of solar street lamp.

Comparison between solar street lamps and commercial street lamps

1, installation comparison

When installing solar street lamps, there is no need to erect complex lines, just make a cement base and battery pit within the range of 1m and fix them with galvanized bolts. The construction process of city street lamps is complicated. First of all, it is necessary to erect auxiliary cables, dig trenches and lay pipes, thread in pipes, backfill and so on, which consumes a lot of manpower, material resources and financial resources. Finally, we have to debug, once there is a problem, it will cause great consumption.

2. Cost comparison

Solar street lamp is a one-time investment and benefits for a long time. Because the circuit is simple, it will not produce maintenance costs and expensive electricity bills. The cost will be recovered in about 3 years, and the electricity cost of city street lamps is high, and the lines are complex, which requires long-term uninterrupted maintenance. Especially in the case of unstable voltage, sodium lamps are prone to failure, and with the extension of years, the aging and maintenance costs of lines will increase year by year.

3. Safety comparison

Solar street lamp adopts 12-24V low voltage, with stable voltage, reliable operation and no potential safety hazard. It is an ideal product for ecological communities and highway departments. There are many hidden dangers of city street lamps. In the ever-changing living environment, road reconstruction, landscape engineering construction, abnormal power supply and cross-construction of water gas pipelines bring many hidden dangers.

During the day, under the illumination condition, the solar cell modules generate a certain electromotive force, and the solar cell array is formed by series and parallel connection of the modules, so that the array voltage meets the requirements of the system input voltage. Then the battery is charged by the charge-discharge controller, and the electric energy converted from light energy is stored. At night, the battery pack provides direct current for the light source. The discharge of the battery pack is controlled by the controller to ensure the normal use of the battery.
