Week 4

Test the previous circuit:



This circuit  function well but we can't use this circuit because it can't recharge the battery.Beside this circuit is only to test our knowledge about the solar.

Week 3

Presentation for final year project


On 16th february 2011,presentation for final year project was held for let the student present about the progress of their final year project at Research Postgraduate Studies (RPS) Meeting Room, Level 6 .There are three lecture was invited to assess the student who present their final year project progress.The purpose of the presentation is to identify the FYP current status and most importantly to have some external inputs & ideas towards the project. Main area to be discussed is Project Ideas, Concept, Project Status, Results (if any..),and Planning.

Week 2

Test the solar circuit that got from internet

Test the circuit that I got from the internet.(http://electroschematics.com/6057/solar-birdhouse-light-circuit/). The circuit name is Solar Birdhouse.To understand how the solar circuit work,I constructing the simple solar Birdhouse.Below this is the picture circuit that I construct:

The circuit above using the battery 12V/4.5Ah to turn on it.But this time I not try the solar panel since I constructing the circuit at night.The problem that I got when testing the circuit is

a) The LED became dim when I put more the 4 LED.

b) The LED that I buying from the store not working well.

c) The multimeter broke

This is the BirdHouse circuit diagram:

Later I will testing the solar panel since it still night .

Week 1

Buy the component


Go to jalan pasar to buy component for solar circuit.

                                                             Solar circuit component receipt

These are some parts that I buy for test the solar circuit:

Specification of a typical 18V/5W solar panel:

Maximum Power (Pm) :5W

Working Voltage (Vmp):18V

Working Current (Imp) :0.28A

Open Circuit Voltage (Voc) :21.2V

                  

                12V/4.5Ah rechargeable battery
