Solar street lights are mainly composed of four parts: solar photovoltaic modules, batteries, charge and discharge controllers, and lighting fixtures.
The bottleneck in the popularization of solar street lamps is not a technical issue, but a cost issue. In order to improve the stability of the system and maximize the performance on the basis of cost reduction, it is necessary to properly match the output power of the solar cell and the battery capacity and load power.
For this reason, only theoretical calculations are not enough. Because the solar light intensity changes rapidly, the charging current and the discharging current are constantly changing, and the theoretical calculation will bring a large error. Only by automatically tracking and monitoring the charge and discharge current can accurately determine the maximum power output of the photocell in different seasons and different orientations. In this way, the battery and the load are determined to be reliable.
