Assembly 

The Solar lamp was assembled as illustrated in the Theory of Operation. Detailed connections are as follows: 

1) The positive of the solar panel was connected to the designated terminal. This is indicated as (1) in the Figure A. 

2) The ground of the panel was connected to terminal (2) 

3)  The positive of the battery was connected to terminal (3) 

4) The ground of the battery was connected to terminal (4) 

5) The positive of the LED was connected to terminal (5) 

6) The ground of the LED was connected to terminal (6) 

The circuit once completed is now a functional solar lamp. However, the lamp cannot be used/hung out in the open without a case. This is because environmental conditions like rain or humidity can damage the battery. Thus it is important to put the battery, LED, and controller in a protective case. 

I chose a plastic plant pot to fulfil this because it is economical and easy to find. The solar panel can be left in the open without any concerns for damage. The circuit installed in the plant pot is shown below. This can now be used by hanging or placing in a convenient location. 

The Solar Charge Controller was assembled as detailed and discussed here. Below is the image of the circuit on the breadboard. The accurate working of the circuit is also shown on the page linked previously. 

The Solar Charge Controller circuit was a working prototype I made on a breadboard to test its validity and give me clarity on the inner workings of a charge controller. However, as discussed previously, it fulfils only one of the three main functions of the Solar Charge Controller. Thus it would not be ideal to use the controller made in the lamp. Thus, further work can be done to achieve this, by implementing ambience sensing, control for electric loads such as LEDs, etc. I could not achieve this because I do not have sufficient knowledge about circuits and electronics yet and also due to the time frame I was required to finish this project in. However, this will definitely be something I will pick up after I finish high school or during college!
