How to choose a good LED solar lawn light?
The solar lawn lamp is an independent solar power system. The utility model can independently convert solar energy into electric energy, and can convert electric energy into heat energy for lighting and decoration use without the transmission of wires. The main system components are photovoltaic power generation systems and power supply systems.
Solar lawn light is a small solar power supply system (such as a small solar power supply system). Its structure is very simple, mainly from solar panels, charge and discharge controller, battery, lighting circuit and lamp parts, such as solar lawn lamp structure diagram shows.Solar lawn lamp - structure compositionIt consists of solar cell module (photoelectric plate), super bright LED lamp (Guang Yuan), maintenance free rechargeable battery, automatic control circuit, lamp and so on.
An independent photovoltaic power generation system generally consists of three parts: solar cell module; charging and discharging controller, inverter, test instrument and computer control of power electronic equipment and battery or other energy storage and auxiliary power generation equipment.Photovoltaic power generation system has the following characteristics: no moving parts, no noise; no air pollution, no waste water; no combustion process, fuel is not needed; simple maintenance, low maintenance cost; reliability and stability; as a key component of the solar battery with long service life, the life of crystalline silicon solar cell can reach according to the need for more than 25 years; it is easy to expand the scale of power generation.
