Someday, if you get a chance to travel to these remote parts of the world, you would amaze to find that how important moon light is!!. These villages have no street lights nor lights at home . Whenever they need some lights they burn kerosene lamps for that.
We have discussed lot of about LED in our " LED Light" post, what about powering it with solar energy.Solar LED is composed of a LED lamp, a photovoltaic solar panel, and a rechargeable battery.
This project idea is for students who are interested in green energy projects. It would be very useful for developing countries , but with one disadvantage that it has more buying cost than any of its counterparts.Even though its operating cost is negligible, we need to provide it on cheaper rates so that it can be afforded even in last part of world.
What we can do ?
Use existing available technology and try to minimize its cost, even if we compromise some of the brightness of light but if you can make it cheaper ,it would change lives of many people.
What's the benefit?
1. It would take years for their government to build power transmission system , which can bring electricity to there places, but solar powered lights can be installed in minutes.
2.Mass production is always cheaper. If people started to buy these lights they would eventually gets more cheaper and better, while reducing dependencies on traditional way of lightning a bulb.
3.It is very reliable and can works in extreme conditions. In the video shown below you can see it.
Concepts :
1) Understanding how a solar cell functions and its limitations with respect to power generation in varying light levels
2) The charging characteristics of various energy storage devices (batteries, ultra-capacitors)
3) The advantages and disadvantages of various power supplies (linear, switching/buck/boost) in matching the current-voltage characteristics of the three system elements.
