Need not. Solar garden lights use solar radiation energy as energy, use solar panels to charge batteries during the day, and batteries to supply power to garden lights at night, without complicated and expensive pipeline laying, the layout of lamps can be adjusted arbitrarily, safe, energy-saving and pollution-free, charging and opening. The /off process adopts intelligent control, light-controlled automatic switch, no manual operation, stable and reliable work, saving electricity costs, and maintenance-free. The solar garden lighting uses CCFL inorganic lamps with a power equivalent to the brightness of 70W incandescent lamps. The lamp post is 3m high and the lamp life is more than 20,000 hours. The quality guarantee period is 25 years. After 25 years, the battery components can continue to be used, but the power generation will decrease slightly. The power generation system has the characteristics of anti-typhoon, anti-moisture, anti-ultraviolet radiation and so on. The system can ensure a daily working time of 4 to 6 hours in a 40 ℃ ~ 70 ℃ environment; in case of continuous rainy days, the usual excess electric energy is stored in the battery, which can ensure that the user still has enough electricity for 2 to 3 consecutive days in the rainy weather The power supply can be used normally. The cost of each solar garden light is 3,000 to 4,000 yuan.
Analysis and comparison of photovoltaic garden lights and ordinary garden lights: the initial installation price of photovoltaic garden lights is 120% to 136% of ordinary garden lights, and the comprehensive cost of the two is basically the same after two years of use. The solar panel receives light to realize photoelectric conversion, converts solar energy into electrical energy, generates direct current, and then charges the battery through the controller, and the battery stores the electrical energy. At night, through the control of the photoresistor, the battery is automatically discharged through the controller, the circuit is automatically connected, and the light bulb is powered by the battery to light up and start working without manual management.
