System composition of solar lawn lamp
Solar lawn lamp is an independent solar power generation system. It can independently convert solar energy into electric energy, and convert electric energy into heat energy for lighting and decoration without the transmission of wires. Even in cloudy days, this solar generator (solar panel) can collect and store solar energy. Its main system components include photovoltaic power generation system and power supply system.
Photovoltaic system
An independent photovoltaic system generally consists of three parts: solar cell module; Charge and discharge controller, inverter, test instrument, computer monitoring and other power electronic equipment and battery or other energy storage and auxiliary power generation equipment.
Photovoltaic power generation system has the following characteristics: no rotating parts, no noise; No air pollution and wastewater discharge; No combustion process, no fuel required; Simple maintenance and low maintenance cost; Good operation reliability and stability; It is easy to expand the scale of power generation as required.
power supply system
Solar lawn lamp is a small solar power supply system. Its structure is very simple, mainly composed of solar panels, charge-discharge controllers, batteries, lighting circuits and lamp poles.
Advantages of solar lawn lamp
① Long service life
At present, most lawn lamps use LED as the light source. The LED has a long service life, can reach more than 100000 hours, and low working voltage. It is very suitable for solar lawn lamps. In particular, LED technology has made a key breakthrough, and its characteristics have been greatly improved in the past five years, and its performance-price ratio has also been significantly higher.
② Adjustable
LED is powered by low-voltage DC, and its light source control cost is low, which makes it possible to adjust the brightness and frequent switching, and will not have a negative impact on the performance of LED.
③ Flexibility
The design method of solar lawn lamp light source and power supply system has developed rapidly in recent years due to the unique advantages of solar lawn lamp. The lawn lamp is small in power, mainly for decoration, and is suitable for places with high mobility requirements, difficult circuit laying, and high waterproof requirements.
