If we break down our energy consumption, we find that lighting is one of our biggest issues because of the amount of light we require daily and the inefficiency of our current lighting solutions. It’s time to realize that traditional light sources aren’t cutting it anymore and move forward to more efficient and sustainable long-term solutions. One such solution that has been gaining a significant amount of attention recently combines the sustainable benefits of solar power with the energy efficiency of LED lighting. Solar power LED lights are the best alternative energy source since they are eco-friendly and come from a limitless source.
The automatic solar power led light is a perfect solution for any outdoor lighting application, from parking lots to street lights. Outdoor lighting is typically only needed during the night, which leaves the daytime for obtaining solar energy that can then be converted to electrical power and used in powering our light sources overnight.

Circuit Diagram
Working Explanation
As shown in the circuit, it consists of a 6V solar panel and 12 high bright white LEDs. You can use a 6V/4Ah SLA battery, which will get charged during day time through solar panel power, and during night time this battery acts as a power source for LEDs. And further in the circuit LDR is placed to drive LED off during day time and on during night time with the help of an SL100 switching transistor.
Applications
This automatic solar-powered LED light can be used for gardens, outdoors, farms, etc…
