Solar light ICs are very handy, they have the dark detection circuit and the voltage multiplying LED driver built into one small four pin component. Using the solar light IC all you need is the solar IC, an inductor, and the ultra-bright LED to make the circuit. Add the battery and the solar cell and you have a solar light.
The system under consideration is an off grid solar streetlamp. The solar streetlamp consists of high power LEDS, a lead acid battery, a solar controller, and a solar panel as shown in Figure 2.

Circuit Diagram and Explanation: Below is the circuit diagram of this Light sensing Street Light: In this project, we have used an LDR (Light Dependent Resistor) which is responsible for detecting light and darkness. The resistance of LDR increases in darkness and reduces in presence of light. This circuit is same as a Dark Detector or Light Detector Circuit, only here we have replaced simple LED with a AC load, using a Relay. Two BC547 NPN transistors are used to drive the relay.
– Solar Panel LED Street Lighting – Solar Panel Battery Charger • Specification : – Input : 12 V – 24 V – Output: 12 V @ 2 A – Protection: Adj Current Limit, Input UVLO, Input OVLO – Maximum peak power tracking required – Efficiency: Target >80% – Isolation Required: YES – Prevent discharging the batteries
This Outdoor LED Solar Garden Lights project is a hobby circuit of an automatic garden light using a LDR and 6V/5W solar panel. During day time, the internal rechargeable 6 Volt SLA battery receives charging current from the connected solar panel through polariy protection diode D9 and current limiting resistor R10.
Solar Lighting System Circuit Capacitor C1 connected in parallel with a 12V relay coil remains charged in daytime until the relay is activated. C1 is used to increase the response time of the relay, so switching occurs moments after the voltage across it falls below 12V.

Simple Solar Circuits: How to get started adding solar power to your small electronics projects. Use the sun to power small solar and battery powered night lights, garden lights, and decorations for halloween. The first part of a solar circuit is… a device for collecting sunlight.
Automatic street light control circuit diagram, In this article I am going to post a very simple circuit diagram of automatic street light control using transistor and light dependent resistors. This is a very simple circuit of automatic street light control.
Efficient automatic solar garder lights circuit with minimum components the best deal is that is completely auto and the Solar panel acts as a light detector. Switches the Lamp off at Dawn, charges the battery during daytime and switches the LED lights ON at dusk providing 100 Lumens illumination during the night.
A very simple automatic solar light system for illuminating your garden passages can be built using some LEDs, a rechargeable battery and a small solar panel. The system automatically switches ON the lamps at dusk and switches them OFF at dawn.
