Solar cell components, supports, lamp posts, lamp holders, special bulbs, batteries, battery boxes, and ground cages made of single crystal silicon or polysilicon are used. Lamp head modelling is colorful, colorful, chic and elegant, solar courtyard lamp can decorate the courtyard, park, amusement park to dress like a picture. The product can be lit continuously for 4-5 days, working 8-10 hours per day, and can be designed according to the special requirements of users.
Solar courtyard lamp lighting adopts CCFL inorganic lamp tube with power equal to 70W incandescent lamp, lamp column is high 3m, lamp tube life is greater than 20,000 hours; The power supply is 35w monocrystalline silicon solar panel, photoelectric timer switch. The quality guarantee period is 25 years, the battery component can continue to be used after 25 years, but the power generation decreases slightly. Power generation system has the characteristics of anti - typhoon, anti - humidity, anti - ultraviolet radiation. System can be in a 40 ℃ ~ 70 ℃ environment to ensure that the daily working time 4 ~ 6 hours. In case of continuous rainy days, the extra energy is stored in the accumulator, which can ensure that the user has enough power supply to be used normally for 2 ~ 3 days in the rainy weather. The cost of each solar garden lamp is 3000 ~ 4000 yuan. Comparing the pv courtyard lamp with the common garden lamp, the initial price of the photovoltaic courtyard lamp is 120% ~ 136% of the common garden lamp, and the combined cost is basically the same after two years.
