• 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 Right Solar Lights How To Choose

  Nov 21, 2022

  Using solar lighting outdoors can be a lifesaver when outdoor outlets are not available. But do solar-powered lights really work? How do they measure up to hardwired electric lights? And what if your yard is shady or you live somewhere that rarely sees the sun?   Here’s the full scoop on choosing and using solar-powered lights in your yard.How solar lighting works. Photovoltaic cells absorb sunlight during the day to charge the batteries, which then light the bulb at night. Because solar lights are powered by the sun, they must be placed in an area that receives full sun — ideally eight or more hours per day.What if you don’t have direct sun? If you are putting solar lights in your desert yard in Tucscon or Palm Springs, they are sure to operate at maximum strength — but what if you live in Seattle or simply have a heavily shaded yard? It’s not quite as simple, but you can still have solar-powered lights, even in a fully shaded area. A solar or landscape lighting pro can help position a remote photovoltaic panel on your roof or in a sunnier area of your yard, which can then be wired to the lights in the shady area.If you’re looking for even good ways to use solar energy around your home, check out our guide to the www.szleadray.com. All the best outdoor solar lights will be optional.As a Solar lighting company specializing in Solar street light for 15 years, We will be lucky if we are a potential supplier for you.     Installation Steps Location Selection: Choose a location that can receive sufficient sunlight throughout the day to ensure that the solar panel can effectively charge the battery. Avoid installing in places with long-term shading objects.   Pole Preparation: If a pole is used, ensure that it is tall enough to provide adequate lighting coverage and strong enough to support the light fixture. Usually, a 2.5-inch GI pole with an outer diameter of 60 mm is preferred. Dig a hole about 3 to 4 feet deep for the pole foundation, and the depth can be adjusted according to the pole height and local regulations. In some cases, concrete may need to be poured for added stability. System Testing: Before fixing all components, test the system. Cover the solar panel to simulate night conditions and observe whether the light turns on, and check whether the light turns off when the solar panel is exposed to sunlight to ensure that all components are functioning properly.     Component Fixing: After confirming that the system is working properly, securely fasten all components to the pole or mounting surface, ensuring that the connection is firm. Final Checks: Cover the solar panel again to check whether the light turns on to ensure that the light is working properly. Tighten any loose bolts or screws, and ensure that the light fixture is positioned correctly for optimal lighting coverage.     Pole Erection: Erect the pole in the dug hole and pour gravel and concrete into it. Place a crossbeam to support the pole until the concrete dries.

• Do solar led lights need direct sunlight

  Feb 20, 2023

  It is not necessary to be exposed to the sun before use.Generally speaking, as long as there is light and battery board, energy can be stored, but the efficiency of the battery board to convert light energy into electric energy is related to light. The stronger the light, the higher the conversion rate.     Description of the working principle of solar street lamp: under the control of the intelligent controller, the solar panel absorbs the solar light and converts it into electric energy through the illumination of the solar light in the daytime, the solar cell module charges the battery pack in the daytime, and the battery pack provides power to the LED light source in the evening to realize the lighting function.For this reason, the light is not so strong, and the battery panel will still power the battery, but the conversion rate will be relatively small.Solar street lamp system can ensure normal operation in rainy weather for more than 15 days!Its system consists of LED light source (including drive), solar panel, battery (including battery insulation box), solar street lamp controller, street lamp pole (including base) and auxiliary materials and wires.The solar cell module generally selects monocrystalline silicon or polycrystalline silicon solar cell module;LED lamp holders generally use high-power LED light sources.     The controller is generally placed in the lamp pole and has light control, time control, overcharge and over-discharge protection and reverse connection protection. The more advanced controller has the function of adjusting the lighting time in four seasons, half-power function, intelligent charging and discharging function, etc.The advantage of solar street lamps is that they generally use high-efficiency energy-saving LED lamps with sufficient brightness.The system configuration of the product adopts the principle of low light power generation of polysilicon solar cells, and the lead-acid maintenance-free battery is used for storage.The lighting state is automatically switched through the time controller, and the light source uses high-efficiency energy-saving lamp/LED lamp for energy conservation and environmental protection. The installation and construction are simple, and there is no need to dig trenches to lay cables.   OEM & ODM Service Brand, Logo,Color, Product Manual, Packaging etc....   20+ Years experience of Solar LED Lighting   Brand, Logo, Lighting mode, Brightness, Product Manual, Packaging, etc.   Shenzhen Leadray Optoelectronic Co., Ltd.
