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

  Feb 16, 2023

  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).
