<p><a href="alltopgroup.com" rel="noopener noreferrer" target="_blank"> Solar street lights</a> are composed of the following parts: solar panels, solar controllers, battery packs, light sources, light poles and lamp housings. If the output power is AC 220V or 110V, you must also configure the inverter.</p><p>1.Solar panel</p><p>The solar panel is the core part of the solar street light and the high value part of the solar street light. Its role is to convert the radiant power of the sun into electrical energy or send it to a battery for storage. There are three types of solar cells, such as monocrystalline silicon solar cells, polycrystalline silicon solar cells, and amorphous silicon solar cells.</p><p>Solar controller</p><p>Regardless of the size of the solar light fixture, a good-performance charge-discharge controller is essential. In order to prolong the service life of the battery, its charging and discharging conditions must be restricted to prevent the battery from overcharging and deep charging.</p><p>3.Battery system</p><p>Since the input energy of a solar photovoltaic power generation system is extremely unstable, a battery system is generally required to work. Generally there are lead-acid batteries, Ni-Cd batteries, and Ni-H batteries.</p><p>4.Light source</p><p>What kind of light source is used for solar street lamps is an important indicator of whether the solar lamps can be used normally. Generally, solar lamps use low-voltage energy-saving lamps, low-pressure sodium lamps, electrodeless lamps, and DLED light sources.</p><p>5. Light pole and lamp housing</p><p>The height of the light pole should be determined according to the width of the road, the distance between the lamps and lanterns, and the illumination standard of the road. According to the information we have collected from many foreign solar lamp housings, between the aesthetics and energy saving, most of them choose to save energy. The appearance requirements of the lamps are not high and they are relatively practical.</p><p>Product parameters:</p><p>1. Main material: overall hot-dip galvanizing / plastic spray treatment of the lamp post, high rust resistance;</p><p>2. Solar cell module: crystalline silicon body 15-120W (configured according to load);</p><p>3. System working voltage: DC 12V-24V;</p><p>4. Controller: dedicated controller for solar lamps, light control + time control, intelligent control (the black light turns on automatically, and the light turns off automatically);</p><p>5. Energy storage battery: Fully enclosed maintenance-free lead-acid battery 12V17Ah—120Ah (based on load configuration);</p><p>6. Light source type: Highlight LED light source, 20-100W (can be configured according to customer requirements);</p><p>7, protection level: IP65;</p><p>8. Operating temperature: -30 degrees to 70 degrees, wind resistance ≥150Km / h;</p><p>9, lighting time: 4 to 14 hours (can be adjusted as required);</p><p>10. Light pole height: 2m ~ 12m (can be made according to customer requirements);</p><p>11, rainy and continuous work (can be produced according to customer requirements).</p><p>Features:</p><p>1. Easy installation, no need to lay complicated lines, just a cement base and fixing with screws;</p><p>2. Long-term benefits of free electricity charges, solar street lights are a one-time investment, no maintenance, and the investment cost is recovered in about 3 years;</p><p>3. The safety factor is high. The solar luminaire uses a safe DC power lower than 36V, and there is no hidden danger to personal safety.</p><p>4. Ultra-long life, the life of solar panels is 25 years; the average life of ultra-bright LED is more than 50,000 hours, and the life of solar special storage battery is 5-7 years</p><p>5, green, environmental protection, light protection vision without flicker, the light does not contain ultraviolet and infrared. The battery does not generate radiation and does not contain harmful elements such as mercury and lead, which is conducive to recycling and utilization.</p><p>Use environment:</p><p>1. Altitude: ≤5000M;</p><p>2. Ambient temperature: -50 ℃ _ + 70 ℃;</p><p>3. Design wind speed: 35m / s;</p><p>4. Relative humidity: 80;</p><p>5. Seismic intensity: Grade 8.</p><p>Applications:</p><p>Mainly suitable for urban roads, community squares, industrial parks, tourist attractions, park green belts, new rural construction, mountain slopes, etc., most places lighting, lighting.</p><p>After-sales service plan and commitment:</p><p>1. Our unit will provide you with technical consulting services related to lighting engineering;</p><p>2. Our company supports and facilitates customers to track and supervise the product manufacturing process;</p><p>3.
