Outdoor Solar Lighting
Some solar lighting systems are self-contained units: You only need to place the lights in a sunny location. Others have the lights separate from a solar cell panel, in which case only the panel needs to be placed in a sunny location. Units vary in size from small, glowing pathway markers to pole-mounted patio and high-beam security lights.
Simple Solar light circuit version II using Li-ion battery
We only use a single diode to prevent reverse current from flowing from the battery to the solar cell. In the circuit above, the current from the solar cell flows through D1 to charge the Li-ion battery. When there is less sunlight, the higher voltage from the battery cannot flow back to the solar cell.
Can Solar Lights Charge in The Shade?
Solar lights charge even if no direct sunlight is available. Cloudy weather may block the sun''s rays, so solar lights need to charge. However, small amounts of solar energy penetrate the clouds even in complete shade. Solar panel cells have no trouble absorbing and converting this light into electrical energy.
