•For example: ESL-16 solar panel: 14.5W, Li-ion battery: 97.68WH, LED: 1200lm, lighting mode: 5Hrs smart lighting + 7Hrs 25% lighting Below is the formula for reference: •LED lighting time: T(time)=battery power/(LED power*energy saving )coefficient=15.35Hrs Lighting time per day：4.75Hrs Lighting days=15.35/4.75=3.2days It means the lighting will work for 3 raining day after battery full charged. •Solar charging time: T(time)=battery capacity/solar charging current=(97.68/3.7)/ (14.5/5.5)=10Hrs, which means it need 2 sunny day for full charing the battery. •Left power after daily solar charging & using: Left power=(daily solar charging-daily using)/daily using=61.6% It means solar charge one day, the lighting will work 1.6days.

What is a reasonable solar street light body structure design

May 26, 2017

First of all, to solve the problem of solar LED lighting mainly relys on a reasonable structure of the lamp body design, a solution is to use 2-3mm thick aluminum plate, high-power LED directly installed in the aluminum plate, LED connected with a lead. Low-power LED can be used in accordance with the number of LEDs in the aluminum tombs on the aperture and LED diameter to do the same hole, and then set the LED inlaid with aluminum tombs, LED pins in the back of the aluminum plate. The lamp housing is also made of metal material, will be installed with LED aluminum plate and metal shell tightly assembled, so that the heat generated when the LED can be transmitted through the aluminum substrate to the metal shell, the metal shell exposed to the air, the heat can Through radiation and convection. LED chip luminous efficiency of the new energy LED lights can make the whole lamp efficiency of 801m / W or more, has the advantage of energy saving, and its reliability and service life will need to rely on packaging technology to further improve. At present, the new energy LED street lamp to promote the application of the bottleneck is not light efficiency, and in the light failure and reliability, high-power LED package on the new energy LED lights light failure and reliability plays a key role. All new energy LED street lamp products in the radiator design, can be roughly summarized as aluminum extrusion heat sink chip heat sink and heat pipe combined with the radiator. Which aluminum extrusion heat sinks are mostly solar LED lighting the appearance of the pieces, the advantages of this approach is the lower cost of the radiator, especially the development costs of mold more competitive. However, in the development of high-power products, the weight is a must pay attention to factors, because the lamp arm tolerance will be some restrictions, so in high-power products, the general use of chip heat sink, or the use of heat pipe The way heat dissipation. High-power LED for the production of outdoor lighting enclosure protection level are generally above IP65. If the housing is a nonmetallic (such as plastic) material, although the LED is connected to the aluminum substrate (MCPCB), if the heat on the aluminum substrate can not be effectively conducted to the surface of the shell, the accumulated heat will cause the temperature of the aluminum plate to rise sharply , Resulting in the temperature is too high, then increase the possibility of LED failure, resulting in LED light decline increased life shortened.

How do you maintain your solar panels of solar street light?

Aug 28, 2020

Worried about solar panels and hail? Fret not, solar panels are incredibly durable and require little to no maintenance over their productive lifetime – which can span 25 years or more. Solar panels are made of tempered glass, so they’re built to withstand hail and other rough weather. With the exception of tracking mounts, solar panel systems don’t have movable parts, which cuts down on the possibility of any problems. Maintaining the solar panels of solar street lights is critical to ensuring their long-term efficiency (typically 25–30 years of lifespan) and stable power supply for the street light. Poor maintenance can lead to a 30–50% drop in energy conversion efficiency over time, shortening the system’s service life and increasing replacement costs. Routine Inspection: Catch Issues Early Routine checks (recommended monthly for urban areas, quarterly for rural/remote areas) focus on identifying visible damage, position deviations, or environmental interference that could affect panel performance. Inspection Item What to Check Potential Risks if Neglected Panel Surface - Cracks, scratches, or yellowing of the glass cover.- Loose or broken frame (aluminum alloy frame is common).- Peeling of the anti-reflective coating (critical for light absorption). - Water seepage into the panel (damages internal cells).- Reduced structural stability (panels may fall in strong winds).- 10–20% lower light absorption. Mounting Structure - Loose bolts, brackets, or rust on the mounting rack.- Tilt angle deviation (should match the local latitude for optimal sun exposure).- Signs of corrosion (especially in coastal areas with salt spray). - Panels shift or tilt incorrectly (reduces daily energy harvest by 15–25%).- Mounting rack collapses (total panel damage). Surrounding Obstacles - Overgrown trees, branches, or new buildings blocking sunlight.- Bird nests, leaves, or garbage accumulated on/around the panel. - Shading causes "hot spots" (damages cells and reduces output).- Debris blocks light and traps moisture (accelerates corrosion). Wiring & Connectors - Frayed cables, loose MC4 connectors (standard for solar panels), or rust on terminals.- Signs of overheating (discolored insulation or melted plastic). - Poor electrical contact (power loss of 5–10%).- Short circuits (may Many people in regions that get significant snowfall often ask if it’s necessary to remove the snow from the panels. Generally, the answer is no – snow usually melts and falls from the panel shortly after falling, so it doesn’t have a big impact on your overall production levels. For your panels to be self-cleaning, they will need to be mounted at an angle of 15 degrees or more.Generally, solar panels don’t need to be cleaned. If you live somewhere where there is a lot of smog, dust, or dirt, you may see a dip in your production over time that can be remedied by cleaning your panels. On rainy days, water can help you clean the dirty on the solar panel.Shenzhen Leadray Optoelectronic Company Specialize in Solar lighting fields for over 15 years, our solar light sold to many countries. The hot selling products range is solar street light, solar garden light, solar parking lot light, etc. If you use our All in One Solar Light, we provide a range of warranties that guarantee you will have support and coverage in the unlikely event of an issue, such as hail or falling tree branches.
