Description

Product Introduction

◎Innovation in self-cleaning technology: The 90W LED solar street lamp adopts mechanical rotating brush (nano hydrophobic coating + micro water spray) and electrostatic adsorption dust removal (high-voltage ionization + vibration shedding) technologies, which are respectively suitable for areas with frequent sandstorms and arid water-scarce areas. The annual power generation is increased by 18%-25%, and the 5-year maintenance cost is reduced by 60%-70%.

◎Green and environmentally friendly full chain: The combination of monocrystalline silicon photovoltaic panels (conversion efficiency >22%) and lithium iron phosphate batteries (3000 cycles, 95% recovery rate) achieves a 95.9% reduction in carbon footprint throughout the life cycle. The annual emission reduction of 100,000 street lamps is equivalent to planting 2.2 million fir trees.

◎Technical parameter scenario adaptation: 90W power is suitable for 8-10 meters road width, 180W photovoltaic panel meets the daily average 4-hour sunshine demand, -20℃ to 55℃ wide temperature range lithium battery combined with intelligent dimming, covering multiple scenarios from urban main roads to desert highways.

Self-cleaning Function

(1) Mechanical self-cleaning system

Mainstream products adopt a composite cleaning scheme of electric rotating brush + nano hydrophobic coating + micro water spray.

◎Nano hydrophobic coating: The surface of the photovoltaic panel is covered with a fluorocarbon resin-based nano coating, with a contact angle >150°, forming a "lotus leaf effect" to make it difficult for dust to adhere;

◎Rotating brush cleaning: The silicone brush (rotating speed 30rpm) that automatically starts every 2 hours, combined with 0.5L/min micro water spray, can remove more than 98% of particles (particle size >5μm);

◎Intelligent control: Linked through photosensitive sensors and humidity sensors, cleaning is started when the sunlight is sufficient and the humidity is <60% to avoid water stain residue.

(2) Electrostatic adsorption dust removal technology

◎Electrostatic adsorption: The frame of the photovoltaic panel integrates a high-voltage electrostatic generator (output voltage ±15kV), which ionizes the air to charge dust particles, and adsorbs them on the negative plate under the action of an electric field;

◎Vibration shedding: A linear vibrator (frequency 50Hz) is started once every 24 hours to make the adsorbed dust fall into the dust collection tank;

◎Sealing design: The dust collection tank adopts IP67 protection level to prevent secondary dust.

◎Advantage analysis: The power consumption of this scheme for a single cleaning is only 0.02kWh, and no water resources are needed. In the northwest region with annual precipitation <200mm, the frequency of manual cleaning can be reduced by more than 90%.

Cleaning Method	Annual Power Generation Increase Rate	Water Resource Consumption (m³/year)	Maintenance Cost (yuan/year)	Applicable Scenarios
Traditional manual cleaning	10%-15%	50-80	2000-3000	Humid and rainy areas
Mechanical rotating brush	18%-25%	10-15 (spray water)	500-800	Areas with frequent sandstorms
Electrostatic adsorption dust removal	15%-20%	0	300-500	Arid and water-scarce areas

Green Environmental Protection Characteristics

(1) Photovoltaic power generation: Zero-emission energy conversion

◎Energy self-sufficiency: Calculated based on an average of 5 hours of effective sunshine per day, the annual power generation of a single lamp reaches 400kWh, which can meet its own lighting needs and realize surplus power grid connection;

◎Emission reduction effect: Each street lamp reduces carbon dioxide emissions by 398kg per year (equivalent to the carbon sequestration capacity of planting 22 fir trees). If calculated on a scale of 100,000 lamps, the annual emission reduction can reach 39,800 tons;

◎Resource conservation: Compared with traditional municipal street lamps, a single lamp saves 160kg of standard coal per year and reduces sulfur dioxide emissions by 3.2kg.

(2) Energy storage system

◎Long service life: More than 3000 cycles, 3 times that of lead-acid batteries, reducing the frequency of battery replacement;

◎Low self-discharge: Monthly self-discharge rate <3%, and 85% of the electricity can be retained after 6 months of idleness;

◎Environmental protection: Does not contain heavy metals such as lead and cadmium, with a recycling rate of more than 95%, meeting the requirements of the RoHS directive.

◎Economic analysis: Calculated with a 10-year life cycle, the total cost of ownership (TCO) of lithium iron phosphate batteries is 40% lower than that of lead-acid batteries, and electronic waste generation is reduced by 60%.
