• How to connect the solar panel to the LED light to make it light

  Controlled by solar controller, it supplies power to solar light source LED energy-saving lamp Use a diode string between the battery and the battery board to prevent reverse charging. The solar panel in the sky receives solar radiation and generates electric energy in the form of chemical energy, which is stored in the battery pack.   2. At night, it is controlled by the solar controller to supply power to the solar lamp light source LED energy-saving lamp to make it glow.   3. When the brightness is higher than the set value during the day, the solar controller will control the output off, the solar energy lamp will stop emitting light, and the battery will continue to charge automatically.     4. The main role of solar cells is to generate electricity. 5. The mainstream of the power generation market is crystalline silicon solar cells and thin film solar cells, both of which have advantages and disadvantages.   6. Crystalline silicon solar cells have relatively low equipment costs, but high consumption and cell costs, but also high photoelectric conversion efficiency. It is suitable for generating electricity in outdoor sunlight.   Connecting a solar panel to an LED light to make it work requires a complete solar power system (not just direct connection between the two), as solar panels produce unstable DC power that needs regulation, storage, and control to match the LED’s power requirements. Below is a step-by-step guide to the system composition, connection principles, and specific wiring methods, suitable for both small-scale (e.g., home garden lights) and medium-scale (e.g., street lamps) applications.   1. Core Components Required (Must-Have) Solar panels generate electricity, but they cannot directly power LEDs—you need 4 key components to form a functional loop. Missing any part will cause the LED to fail (e.g., flickering, burnout, or no light).   Component Function Key Selection Criterion Solar Panel Converts sunlight into DC electricity (usually 12V/24V). Match the system voltage (e.g., 12V panel for 12V LEDs) and power (≥ LED + battery loss). Rechargeable Battery Stores solar electricity for nighttime or cloudy-day use. Use deep-cycle lead-acid batteries (low cost) or lithium-ion batteries (long life); voltage matches the system (12V/24V). Solar Charge Controller (SCC) Protects the battery from overcharging/over-discharging; regulates power to LEDs. Must match system voltage (12V/24V) and current (≥ solar panel’s maximum current). LED Light The load (lighting part). Choose DC LED lights (most common for solar systems); voltage matches the system (12V/24V to avoid burnout).   2. Why Direct Connection (Solar Panel → LED) Fails Many beginners try to connect the solar panel directly to the LED, but this leads to problems:   Unstable voltage/current: Solar panel output depends on sunlight (e.g., 18V open-circuit voltage in strong light, near 0V at dusk). LEDs need stable voltage (e.g., 12V), so direct connection causes flickering or burnout. No energy storage: The LED will only light when the sun is shining (no light at night). Battery damage risk: Without a charge controller, the battery will overcharge (swell/explode) or over-discharge (permanent damage).   3. Step-by-Step Connection Method (12V System as Example) We take a common 12V system (e.g., 10W solar panel + 12V 7Ah battery + 12V 5W LED) as an example. The wiring order follows the "Solar Panel → Charge Controller → Battery → LED" loop (current flows in one direction, do not reverse polarities).

• 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.
