When purchasing streetlight solar panels, the focus is on the power of streetlight solar cells. In general, the power of streetlight solar panels is proportional to the area of solar cells. The area of the solar cell wafer is not completely equivalent to the area of the solar package panel, because some street lamp solar panels are large, and the slits of the single solar wafer array are wide, and the power of such street lamp solar panels is not necessarily high.

Since the input energy of the street light solar panel photovoltaic power generation system is extremely unstable, it is generally necessary to configure the battery system to work, and the solar light fixture is no exception, and the battery must be configured to work. Their capacity choices directly affect system reliability and system price. The choice of battery capacity generally follows the following principles: First, the energy of the daytime solar cell module is stored as much as possible while meeting the nighttime illumination, and at the same time, it is also possible to store the electrical energy required for the nighttime illumination of the continuous rainy day. If the battery capacity is too small, it can not meet the needs of night lighting. The battery capacity is too large. On the one hand, the battery is always in a deficient state, which affects the battery life and causes waste.

Solar panel is a device that directly or indirectly converts solar radiation energy into electric energy through photoelectric effect or photochemical effect by absorbing sunlight. The main material of most street lamp solar panels is “silicon”, street lamp solar cell. The main function of the board is to generate electricity.
