Notice that I didn't use the transistor's emitter pin, just the base pin and the collector, which is the case of the transistor. I did this because when I measured the power output for all possible wiring combinations for a single solar cell, using the base as the positive connection and the collector as the negative gave the best results as the following table shows.
Here in this project we are going to make a Simple Automatic Street Light Controller Using Relay and LDR. This circuit is simple and can be built with Transistors and LDR, you don't need any op-amp or 555 IC to trigger the AC load.
Assuming about 0.5 volts per cell, the minimum number of solar cells to charge the battery is eight. However, the charge control circuit will need to be very efficient with a very low voltage drop, since there would not be much of a margin between what the solar panel can deliver and what the battery needs.
Because, this solar powered street light can conserve a large amount of electricity compared to the other lights which are a light to their maximum intensity at all times after they are turned on Solar Powered Led Street Light with Auto Intensity Control Circuit and Its Working. Solar Powered LED Street Light by
The system will provide a self-sufficient street lamp lumen system that will allow cities to take streetlights off the power grid. The system itself is seen in Figure 2 and will contain four major components, a solar panel, battery, charging circuit, and a LED driver. The solar panel will charge the battery during daytime.
The post distinctly adds a simple Automatic 40 Watt LED Solar Street Light Circuit Project Part-2 that can be constructed by every new hobbyist for custom-made usage and also entertaining
The Application of Solar Powered LED Street Lighting • LED lighting offers high efficiency, long operating life and low voltage operation which ideal for solar • Solar street lights were initially used in remote locations and disaster prone areas • As LED efficacy and light output have improved, they are becoming mainstream
A very useful simple to build automatic solar garden light circuit that is able to serve as a night lamp for your garden or other places. The circuit is very easy to build using only one transistor and few other parts.

Emergency household lighting using power LEDs powered by the solar panel and lead acid battery - solar technology Solar Powered Led Lights Solar Lights Solar Installation Solar Panel System Solar Panels Lead Acid Battery Red Smoke Emergency Led Lights Schematic Design
Here is a very useful project of an automatic street light or lamp circuit which can be used to activate your outdoor lights like garden lamps, night lights etc. automatically when the sun set and turn off automatically when the sun rises. The circuit is quite sensitive and versatile and can be used
Solar cells generate direct current, so make sure that DPDT switch S1 is towards the solar panel side. The DC voltage from the solar panel is used to charge the battery and control the relay. Solar Lighting System Circuit. Capacitor C1 connected in parallel with a 12V relay coil remains charged in daytime until the relay is activated.
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.
Device in solar LED street light system The solar street lighting system consists of many sections. In this chapter, only the Solar panel, the Battery, the Controller and the Led lights are briefly introduced. 2.1 Solar panel 2.1.1 Working principle The Photovoltaic (PV) cell is composed of at least two layers of the semiconductors
Solar street light is charged by solar in daytime and bright in night, there are lithium battery built-in, different configuration can meet different requirement. Let us take some examples to introduce the configuration for solar street light. Calculate Current For example: A solar street system, 2pcs 30W LED lamps, 12V lithium battery.

sir,we want automatic street light controller by using timer and counter.we want controlling the street light as follows,day time-6.30a.m to 6 p.m-light off,6.30 p.m to 7.30 p.m-light glows alternately,7.30 p.m to 6 a.m-light on,6 a.m-7 a.m-light glows alternately.So please send related circuit diagram,we are waiting for your circuit diagram.
The advantage of Solar Lawn Light Solar Lawn light is to exploit LED as lighting source, its lifespan is long with above 50000 hours, low working voltage, LED is very suitable for solar lawn light, especially the LED technology has got a great achievement and its property has a large improvement in past 5 years, its cost performance has got a ...
This is simplest automatic solar night light circuit that my son try to make it for basic small solar charger. This circuit is a simplest circuit. He trial it to learn about solar LED light, and makes it all by himself. He needs one LED light that brightest at night. But in daytimes it will go out and charged current to battery.
Solar panels and battery configuration for solar street light solar panels and battery configuration formula: First, calculate the current For example: 12V battery system, 2 pcs lamps, 30W each, total for 60 watts. Current = 60W ÷ 12V = 5 A Second, calculate the battery capacity needs
Presented here is the circuit of a solar light that is bright enough to illuminate a garden while not requiring any wiring to the grid supply and thus lowering the electricity bill. Solar light circuit. Circuit diagram of the solar garden light is shown in Fig. 1.
When it's bright the solar cell charges the 2xAAA 1.2v batteries. When it's dark the batteries power the LED. Using a BC557 transistor.
The first step in designing a solar street light system is to find out the total power and energy consumption of LED light and other parts that will need to be supplied by solar power, such as WiFi, Camera etc. need to be supplied by the solar PV system. How to calculate total consumption of your solar system? Simply follow the steps below:
This is basically a Schmitt Trigger circuit which receives input from a cadmium sulfide photo cell and controls a relay that can be used to switch off and on a street lamp at dawn and dusk. I have built the circuit with a 120 ohm/12 volt relay and monitored performance using a lamp dimmer, but did not connect the relay to an outside light.
utilization) control of street light using various electrical as well as electronic components. The circuit named auto intensity control of street light with solar tracker is designed using microcontroller along with real time clock (RTC) and Light Dependent Resistance (LDR).
The main aim of this project is to develop LED based street lights with auto intensity control system by using Arduino board and solar power from photovoltaic cells.
